Thread: Is there a standard C function to do this?

I wrote some code today to accept user input for first and last names and then make sure it's formated as such: Randy Collins

So if the user types RaNDy or rANdY or randy it will format it and then output. My program works fine, but I was wondering if there was a Standard C function I haven't found yet that will do this much easier/faster?

Code:

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

int tolower( int c );
int toupper( int c );

int main() {

char FirstName[21];
char LastName[21];
int i, x;

	printf( "Please enter your FIRST name: " );
	scanf( "%[^\n]%*c", FirstName );

	printf( "Please enter your LAST name: " );
	scanf( "%[^\n]%*c", LastName );

		printf( "\nYour full name is: " )

			for ( i = 0 ; FirstName[i] != 0 ; i = i + 1 ) { 
			
				for ( x = 0; x < 1; x = x + 1 ) {
			                printf( "%c", toupper( FirstName[i] ) );
				i = 1;
				}

			printf( "%c", tolower( FirstName[i] ) );
			}


			printf(" ");


			for ( i = 0 ; LastName[i] != 0 ; i = i + 1 ) {

				for ( x = 0; x < 1; x = x + 1 ) {
			                printf( "%c", toupper( LastName[i] ) );	
				i = 1;
				}
 
			printf( "%c", tolower( LastName[i] ) );
			}

return 0;
}
