C program to convert a string to upper case

Introduction

C program to convert a string to upper case. 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 string[1000];

   printf("Input a string to convert to lower case\n");
   gets(string);

   printf("Characters in Uppercase: \"%s\"\n",strupr(string));

   // strupr is use to convert lower case character to upper case

   return  0;
}

Result
