Convert a character to an upper case alphabetical character.
<ctype.h>
int toupper (int c);
c
Returns the corresponding upper case alphabetical character if the
argument was originally lower case; otherwise, returns the original
character.

case.
#include <ctype.h> /* for toupper */
#include <stdio.h> /* for printf */
int main(void)
{
}
Output:
b changes to upper case B
B remains upper case B
@ has no upper case, so @ is returned
int ch;
ch = 'b';
printf("b changes to upper case %c\n",
ch = 'B';
printf("B remains upper case %c\n",
ch = '@';
printf("@ has no upper case, ");
printf("so %c is returned\n", toupper(ch));
toupper(ch));
toupper(ch));
The character to convert to upper case.
