How can you convert numbers to ASCII code in the C language?

In the C language, you can use type casting to convert numbers into their corresponding ASCII codes. ASCII codes are character set encodings represented as integers, and their values can be obtained by converting the character type to an integer type.

Below is an example code that converts numbers to their corresponding ASCII codes and outputs them.

#include <stdio.h>

int main() {
    int num;
    printf("请输入一个数字：");
    scanf("%d", &num);
    
    // 将数字转换为对应的ASCII码
    char ascii = (char) num;
    
    // 输出ASCII码
    printf("ASCII码为：%c\n", ascii);
    
    return 0;
}

After running the program, the user will be prompted to input a number, which will then be converted to its corresponding ASCII code and displayed as output.

Please note that when converting a number to ASCII code, make sure the number is within the valid range of ASCII, which is between 0 and 127. Otherwise, the conversion result may not correspond to the expected ASCII code.
