WebMay 22, 2015 · In C, a string, as you know, is a character pointer (char *). If you want to swap two strings, you're swapping two char pointers, i.e. just two addresses. In order to do any swap in a function, you need to give it the addresses of the two things you're swapping. So in the case of swapping two pointers, you need a pointer to a pointer. WebThis function illustrates many C program points: for loop not used for simple counting operation. x >>= 1 => x = x>> 1; for loop will repeatedly shift right x until x becomes 0. use expression evaluation of x & 01 to control if. x & 01 masks of 1st bit of x if this is 1 then count++ .
