How to print a character but by using variable?

Question

Simple example for my problem:

char answer;

printf("enter your favorite letter: \n");

answer = getchar();

Now here is the problem. I want to print that character in screen. But by using "answer" variable. Something like this:

printf(answer);

But of course it doesn't work. What do I do?

Answer 1

Are you just after the command to print a char to the console?

int main() {
    char answer;

    printf("enter your favorite letter: \n");

    answer = getchar();

    printf("%c\n", answer);
}

Answer 2

You need to use printf. This lets you 'embed' variables in output using placeholders declared with % prefixes.

The placeholder for a character is %c, so you could use the following:

printf("Your favorite letter is %c", answer);

answer is passed as a parameter and replaces the %c.

This question should give you more information about printf.
