Introduction

C program to find string length. I have used Code:: Blocks compiler for debugging purpose. But you can use any C programming language compiler as per your availability

#include <stdio.h>
#include <string.h>

int main()
{
   char str[100];
   int length;

   printf("Enter a string to calculate it's length\n");
   gets(str);

   length = strlen(str); // strlen to find string lenth

   printf("Length of entered string is : %d\n",length);

   return 0;
}

Result
