How to output characters in the C language.

In C language, you can use the printf function to display characters. The specific syntax format is:

printf("%c", character);

%c is a formatting control symbol used to specify outputting a character, where ‘character’ is the character to be outputted.

The sample code is as follows:

#include <stdio.h>

int main() {
    char ch = 'A'; // 定义一个字符变量
    printf("%c\n", ch); // 输出字符A

    return 0;
}

The result of the operation is:

A

Please note that in the printf function, %c can only be used to output a single character. If you want to output a string (multiple characters), you need to use the %s format specifier.
