itoa() takes the integer input value input and converts it to a number in base radix. The resulting number a sequence of base-radix digits.

Example:

/* itoa() example */
#include <stdio.h>
#include <stdlib.h>

int main ()
{
	int no;
	char buff [50];
	printf ("Enter number: ");
	scanf ("%d",&no);
    
	itoa (no,buff,10);
	printf ("Decimal: %s\n",buff);
    
	itoa (no,buff,2);
	printf ("Binary: %s\n",buff);
    
	itoa (no,buff,16);
	printf ("Hexadecimal: %s\n",buff);
    
	return 0;
}

Output:
Enter a number: 1250
Decimal: 1250
Binary: 10011100010
Hexadecimal: 4e2
