In my last post I had discussed about how to reverse a string. In this post I am showing another method of reversing a string. I will use a pointer here to reverse the string. In this way I took my input in an character array and then assigned the array into a character type pointer. After that I searched the NULL character using pointer asthmatics. And finally printed the string using pointer in reverse order. Now see the code:
#include <stdio.h> int main() { char str[1000], *ptr; int i, len; printf("Enter a string: "); gets(str); ptr = str; for(i=0;i<1000;i++){ if(*ptr == '\0') break; ptr++; } len = i; ptr--; printf("Reversed String: "); for(i=len; i>0; i--){ printf("%c",*ptr--); } return 0; }
