We will learn about strcmp string function in C programming Language
Description
strcmp() – In the C Programming Language, the strcmp function is a comparison operator. It compares two Strings and displays an integer value returns either negative, positive integer or zero
Declaration
Syntax for strstr() function is given below
int strcmp(const char *str1, const char *str2);
Parameter or arguments

str2 – This is the second string to be compared
Returns
strcmp is a predefined string function in C language used to compare two strings. This function returns either negative, positive integer or zero
if Returns value=0, then it denoted String 1 is same as String 2.
if Returns value<0, then it denoted String 1 is less than String 2.
if Returns value>0 , then it denoted String 1 is greater than String 2.
Required Header
the required header for strcmp() String function, in C Programming language, is:
#include<string.h>
strcmp string function in C
Example
Program 1
#include <stdio.h>
#include <stdlib.h>
int main()
{
char first[100], second[100];
printf("Enter the first string\n");
gets(first);
printf("Enter the second string\n");
gets(second);
if(strcmp(first,second)==0)
printf("Entered strings are same\n");
else
printf("Entered strings are not same\n");
getch();
return 0;
} When above program me is compiled it will produce the following result
you have entered same string – output here
Enter the first string hello Enter the second string hello Entered strings are same
you have entered different string – output here
Enter the first string hello Enter the second string world Entered strings are not same
