Convert numbers to strings using the C programming language.

In C language, you can convert numbers to strings using the sprintf() function. The prototype of this function is as follows:

int sprintf(char *str, const char *format, ...)

In this case, ‘str’ is an array of characters used to store the converted string; ‘format’ is a string used to specify the output format of numbers; and ‘…’ are variable parameters used to specify the numbers to be converted.

Here is an example program that converts an integer to a string and outputs it:

#include <stdio.h>

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

When you run the program, the output is:

The converted string is: 123

In this example, the sprintf() function converts the integer num to a string and stores the result in the str array. The converted string is then output using the printf() function.
