String Compare in C
- The strcmp() function takes two strings and return an integer.
- The strcmp() compares two strings character by character.
- If the first character of two strings are equal, next character of two strings are compared.
- This continues until the corresponding characters of two strings are different or a null character '\0' is reached.
- It is defined in string.h header file.
Sample Code
#include<stdio.h>
#include<string.h>
void main()
{
char str1[20],str2[20];
printf("Enter 1st string: ");
gets(str1);
printf("Enter 2nd string: ");
gets(str2);
if((strcmp(str1,str2)==0))
printf("Strings are equal\n");
else
printf("Strings are not equal\n");
getch();
}
