Explanation:-

In this problem, we are comparing a two string using pointers for comparing a two sting we are not using a strcmp function we are comparing with the help of pointer.

First take a input through from user first ake a first string and take a second string and assign both string in two pointer type variable separately, after that run a while loop and put the condition while string1 and string2 is same and also both string not equal null till increase the both string by one character and repeat the process again and again. If the first string is same to a second string then print the message "Both Strings Is Same" if not then print "Both Strings Is Not Same" on screen.

#include<stdio.h> int main() { char string1[50],string2[50],*str1,*str2; int i,equal = 0; printf("Enter The First String: "); scanf("%s",string1); printf("Enter The Second String: "); scanf("%s",string2); str1 = string1; str2 = string2; while(*str1 == *str2) { if ( *str1 == '\0' || *str2 == '\0' ) break; str1++; str2++; } if( *str1 == '\0' && *str2 == '\0' ) printf("\n\nBoth Strings Are Equal."); else printf("\n\nBoth Strings Are Not Equal."); }
