A pointer is said to be constant pointer when the address its pointing to cannot be changed. Lets take an example : char ch, c; char *ptr = &ch ptr = &c In the above example we defined two characters (‘ch’ and ‘c’) and a character pointer ‘ptr’. First, the pointer ‘ptr...
const Pointer in CConstant PointersA constant pointer in C cannot change the address of the variable to which it is pointing, i.e., the address will remain constant. Therefore, we can say that if a constant pointer is pointing to some variable, then it cannot point to any other variable...
To initialize a pointer to null or to assign the null value to an existing pointer, a null pointer constant (NULL, or any other integer constant with the value zero) may be used.static initializationalso initializes pointers to their null values. ...
NULL Pointer in C - A NULL pointer in C is a pointer that doesn't point to any of the memory locations. The NULL constant is defined in the header files stdio.h, stddef.h as well as stdlib.h.
String Literal = string constant// string Printf(“computer”); [which we write in ““ that is called string constant or literal or string] Char s [10] = “computer”; Printf(s); only write s means it represents the address of the first block of the array s []. It means here we...

But const functions and associated consts are evaluated only when referenced. This can result in undefined behavior in a library going unnoticed until the function or constant is actually used. Therefore, this lint specifically targets pointer to integer transmutes in const functions and associated con...
null pointer assignment 中文意思是”空指针赋值“ 或者 ”指针没有赋值“通常在编程c语言，当指针变量刚定义时，它的值是不确定的，因而指向一个不正确的单元，若在这个时候引用指针变量，可能产生不可预料的后果。为了避免这个问题的产生，定义后给它一个确定的地址值。其中pointer [英][ˈ...
