C Programming Tutorial
The strupr(string) function returns string characters in uppercase. Let's see a simple example of strupr() function.
#include<stdio.h>
#include <string.h>
int main(){
char str[20];
printf("Enter string: ");
gets(str);//reads string from console
printf("String is: %s",str);
printf("\nUpper String is: %s",strupr(str));
return 0;
}
Output:
Enter string: rama
String is: rama
Upper String is: RAMA
