Convert ASCII to Letters in C: Quick Guide

In C language, you can convert ASCII codes to letters using the following methods:

#include <stdio.h>

int main() {
    int ascii_code = 65; // ASCII码值，例如65代表字母'A'

    char letter = (char)ascii_code; // 将ASCII码值转换为对应的字符

    printf("The letter corresponding to ASCII code %d is %c\n", ascii_code, letter);

    return 0;
}

In the code, we convert the ASCII value 65 to the letter ‘A’, and use the %c format specifier to print the converted letter. By casting char, we can convert the ASCII value to the corresponding character.
