Since people have already commented on the oversights (?) in your code, I won't
add any more.  So here's a piece of code that does the trick, but is perhaps
best implemented as a function:


/* --- Cut here --- */

#include<stdio.h>
#include<ctype.h>

main()
{
	char *work, *duh= "Hello";

	printf("%s\n",duh);

	/* The important piece follows... */

	for( work= duh; *work; work++ )
		if( islower(*work) )
			*work= toupper(*work);
	
	/* That was it ! */

	printf("%s.\n",duh);

	exit(0);
}

/* --- Cut here --- */

I hope that this might help you to solve your problem.  Have a good day...
