Thread: Need some Help

Well this is my first time to the forum and im trying to finish a project for my c programming class --- anyway my question is this.

how can i assign the ascii value of a character to a variable and vice versa?

This is what I really wanna do--

a user inputs "A", then the program finds the ascii of "A" (which i think is 75) and assigns it to a variable and outputs it.

I know this might be easy for some of you folks so please take a hot second and help me out!

thanks a million.

Code:

char c; int i;

c = getchar();
if( c > 'A' && c < 'Z' || c > 'a' && c < 'z' ){
    i = atoi(c);
    printf( "%d", i );
}

Of course, this assumes that your input can only be letters.

THANK YOU!!!!

Is there some kind of include that i have to put so that the atoi() will work?

Sorry, I way overcomplicated that. That's what happens when I don't code C for a while :P This works better:

Code:

#include <stdio.h>

int main(void){
	char c; int i;

	c = getchar();
	i = c;
	printf( "%d", i );
        /*Alternative*
        c = getchar();
        printf( "%d", c );
        */

	return 0;
}

-Prelude

Thanks again
