Implementing integer to ASCII conversion in C language.

To convert an integer to ASCII code in C language, the character type “char” can be used. In C language, integer types are automatically converted to character types.

Here is an example code for converting integers to their corresponding ASCII characters:

#include <stdio.h>

int main() {
    int num;
    printf("请输入一个整数：");
    scanf("%d", &num);
    
    char ascii = (char)num;
    printf("ASCII码为：%c\n", ascii);
    
    return 0;
}

In the code above, we first use the scanf function to get the integer input from the user and store it in the variable num. Then we convert the integer type num to the character type ASCII and print out the corresponding ASCII character.

Please note that this conversion only applies to integers in the range of 0 to 255. Integers outside of this range will be truncated, with only the lowest 8 bits being taken into account.

You can use the sprintf function to convert an integer to its string representation in ASCII code.

#include <stdio.h>

int main() {
    int num;
    char ascii[4];
    printf("请输入一个整数：");
    scanf("%d", &num);
    
    sprintf(ascii, "%d", num);
    printf("ASCII码为：%s\n", ascii);
    
    return 0;
}

In this example, we have defined a character array called ascii with a length of 4 to store the converted ASCII code string. Later, we use the sprintf function to convert the integer num into a string representation of the ASCII code and then print it out.
