inmain(), argv is an array of pointers. The last element in the array(argv[argc])is always a null pointer. That's a good way to run quickly through all the elements: /* A simple program that prints all its argu
Following C program demonstrates how to compare two function pointers if they are equal and unequal to each other. #include <stdio.h> int retMax (int n1, int n2) { return (n1 > n2) ? n1 : n2; } int main () { //declare two function pointers int (*ptrMaxFunctin)(int, int); ...
But In C language we do not have the freedom to start the array index from any other number than zero, and language strictly sticks to zero as start index of array. It is because in C the name of an array is a pointer, which is a reference to a memory location. Therefore, an expr...
