Output will not work

I practiced the "if, else" on my own. When I hit the play button, it said my build was successful, but the output bar went away and nothing was displayed. I was not prompted that there were errors in the code. Spent a while trying to figure out what happened. Any tips?

Thanks, Caleb

The closing curly bracket should be after the line I mentioned min_value = 'b';. Otherwise the block will only be executed when - as you already recognized yourself - b is smaller or equal than a.

So it looks something like this:

if (a < b) {
    minimum = a;
    min_value = 'a';
} else {
    minimum = b;
    min_value = 'b';
}
    printf("%c %d is the minimum\n", min_value, minimum);

Hey Caleb!

Please could you post the code that you are having problems with?

int a = 11; int b = 9; int minimum; char min_value;

if (a < b) {
    minimum = a;
    min_value = 'a';
} else {
    minimum = b;
    min_value = 'b';

    printf("%c %d is the minimum\n", min_value, minimum);

the output works when b is less than a. When I make a less than b, blank screen. I am sure it is something minor, but my eyes cannot find it.

Thanks for the help.

As far as I can see you are missing a curly closing bracket after your line min_value = 'b';
