const char *p and char const *p

 

 

 

 

Answer: In const char p, the character pointed by ?p? is constant, so u cant change the value of character pointed by p but u can make ?p? refer to some other location. Some of the words are not in the same order. (theres no semantic difference until the const moves relative to the star). CONST char CONST p: here CONST is coming before the "" as well as after the "".In a char const p, the ptr p is constant not the character refered by it, so u can not make p refer to anyother location, but u can change the value of the charac pointed by p. A: The first two are interchangeable they declare a pointer to a constant character (you cant change any pointed-to characters). char const p declares a constant pointer to a (variable) character (i.e. you cant change the pointer). Are there any Difference between const char p and char const p.1) const char p - Pointer to a Constant char (p isnt modifiable but the pointer is) 2) char const p - Also pointer to a constant Char. const charp - p is pointer to the constant character. i.e value in that address location is constant. const char const p - p is the constant point char const is a constant pointer to a char, [behaving like a reference type] you can change the value pointed to but you cant change the pointer. 1. Is "const char const p" a valid construct? 2. How do I align a given structure, say, at 32-byte boundary?1. Is "const char const p" a valid construct? Yes. Both p and the char to which p ponts are const. > const char p and char const p , both are pointer to constant. It means pointer cant modify the content of location where it points, but pointer can point to something else. In const char p, the character pointed by p is constant, so u cant change the value of character pointed by p but u can make p refer to some other location.

Const char p P, is, a, pointer, to, constchar, Char const p ditto, because there is no const operator in C, so const can only belong to the previous type. 1) const char p - Pointer to a Constant char (p isnt modifiable but the pointer is) 2) char const p - Also pointer to a constant Char. However if you had something like: char const p - This declares p to be a constant pointer to an char. const char p means the char value pointed by p is constant we cant change anyway but the address(location) of p can change. 1) const char p - Pointer to a Constant char (p isnt modifiable but the pointer is) 2) char const p - Also pointer to a constant Char. However if you had something like: char const p - This declares p to be a constant pointer to an char. This video will explain popular quesion of C difference between const char ptr char const ptr but why in 19? Is const char pointer and char cons pointer Same?It has to do with asteriks and the position of the const keyword! More precisely you should look up the difference between " const char" and "char const".

Difference between const char p and char const p [duplicate].First of all, whats the difference between: (1) const char (2) char const (3) const char const Im fairly certain I understand this fully, but Id like someone to give me a sentence for each, spe. In char const p, the ptr p is constant not the character referenced by it, so u cant make p to reference to any other location but u can change the value of the char pointed by p. int const mutablepointertoconstantintchar const p both are same. p is a constant character pointer, and q is a constant pointer to a character. 2. char const p: This means the same as in 1.The character is modifiable, but the pointer cannot. The meaning of the code can be interpreted by reading the code from your right hand side to your left hand side. char p "abc" They never intended to modify the string but since C at that time didnt have a " const" keyword they obviously couldnt declare it. If the C standard then had made a string literal const you would suddenly get a zillion compiler errors because of code like this. string is an array of characters, const char p means that a pointer holds an address of another pointer that holds an address of memory location so its value is const char, also that value can not be change to const identifier. In third case const char const p it is a constant pointer to the constant char.char p is type of variable charcont p will store values of p which are constant contant char is atype of symbo, defined for constant characters. int main() static const int size 5 char p new char[size] strncpy( p, "abcd", size)Here constcast has been used the same way you are going to obey limitation of non- const reference initialization in your example cited above. You cannot change the value pointed by p, but you can change the pointer p itself. const char p - This is a constant pointer to non-constant character. const char const thestring: I cannot change thecharto whichthestringpoints, nor can I modify thecharat which it points.const char meansonlythe data the pointer pointed to, is const. pointer itself however is not const. In C Programming, What is the most efficient way to count the number of bits which are set in a value? What is the differnce between " const char " and " char const "? There is no difference between. Const char . And. Char const . They are both pointers to constant chars. Actually in the case of const char there are no pointers. What you say usefully applies to const char but that was not the type mentioned in the question. It is worth noting that const can become a little confusing when pointer come into the mix. const char const p - This is a constant pointer to constant character. You cannot change the value pointed by p nor the pointer p. p A is illegal. p "Hello" is also illegal. constants pointers."char const p" gives a compile time error. Jamie. 2. char const p, and char const p : both are same in this case p is a constant pointer poiting to some char location. you can change the contents of that location but u cant change the pointer to point to some other location. hope i answered the way u wanted !! Discuss Aricent Interview Questions in forum, Read answers, post your answer and get reviewed from visitors. char const p is a const pointer to a (non-const) char.(Char p is modifiable but the pointer isnt). Difference of various const declarations in C. The first two are the same. Q: Whats the difference between const char p, char const p, and char const p? A: The first two are interchangeable they declare a pointer to a constant character (you cant change any pointed-to characters). char const p declares Prerequisite: Pointers There is a lot of confusion when char, const, , p are all used in different permutaions and meanings change according to which is placed where. Following article focus on differentiation and usage of all of these. In char const p, the ptr p is constant not the character referenced by it, so u cant make p to reference to any other location but u can change the value of the char pointed by p. Constant pointer to a constant character. const char const pConst char by contrast, points to constants defined in the DATA section of the executable. And, as such, you cannot modify the character values of a const char string. Difference between const char p and char const p?const char p > cannot change the contents to which it is pointing char const p > cannot change the pointer address - ibnipun10 July 28, 2010 | Flag Reply. char const p declares p as a constant pointer to character pointer. but since i didnt get the exact meaning of these so please verify it. char const p means the character pointer that p points to cannot be changed. const char const p - This is a constant pointer to constant character. You cannot change the value pointed by p nor the pointer p. p A is illegal. p "Hello" is also illegal. Difference between const char p and char const p ?in char const p, the ptr p is constant not the character referenced by it, so u cant make p to reference to any other location but u can change the value of the char pointed by p. Difference between const char p, char const p and char const p interview question faced by c developer Constant pointer to variable.03/09/2003 Hi, can anyone explain with an example the difference between const char and char Thanks in advance. char const p- constant pointer to character Essentially first and second mean the samepointer to const char means means you iterate through location pointed by pointer So char const is a "pointer to a const pointer to a char". This meansFor the second param, the function takes a char const (ie: a pointer to a pointer) and youre only giving it a char (a pointer). in const char p, the character pointed by p is constant, so u cant change the value of character pointed by p but u can make p refer to some other location.

const char p char const p char const p const char const p And this is my understanding here, if anything wrong, would anyone please point it out?char const p A const pointer pointing to a regular char. const char const p - This is a constant pointer to constant character. You cannot change the value pointed by p nor the pointer p. p A is illegal. p "Hello" is also illegal. Difference between const char p and char const p ?In const char p, the character pointed by p is constant, so u cantchange the value of character pointed by p but u can make p refer to Answer:- First two const char p and char const p both are same i.e. points to constant character(You can change where p points, but you cant change pointed characters using that pointer).
