Compare two Strings in C Language!

In this post, you will learn how to compare two strings using C language. There is a function strcmp() available in core C. It accepts two string parameters and returns an integer value and if the value is 0 then both the strings are equal otherwise not equal.

Let’s see the C program to compare two strings using strcmp(str1, str2):

#include <stdio.h>
int main() {
	char str1[100], str2[100];
	
	//get the strings from the user
	printf("First String: ");
	scanf("%s", &str1);
	
	printf("Second String: ");
	scanf("%s", &str2);
	
	if ( strcmp(str1,str2) == 0 ) {
		printf("Both the strings are equal!");
	}  else {
		printf("Both the strings are not equal!");
	}
	return 0;
}

Sample Output of the above program is:

First String: test
Second String: one
Both the strings are not equal!
