How to convert an int to a string in the C language?

In C language, the standard library function sprintf() can be used to convert an integer to a string. For example:

#include <stdio.h>

int main() {
    int num = 123;
    char str[10];
    
    sprintf(str, "%d", num);
    
    printf("Converted string: %s\n", str);
    
    return 0;
}

In this example, the sprintf() function converts the integer num into a string and stores it in the str array. The converted string is then printed out using the printf() function.
