Write a C Program to convert a positive decimal number to Binary, Octal or Hexadecimal

#include<stdio.h>
void convert(int, int);
int main(void)
{
	int num;
	printf("Enter a positive decimal number : ");
	scanf("%d",&num);
	convert(num,2);
	printf("\n");
	convert(num,8);
	printf("\n");
	convert(num,16);
	printf("\n");
	return 0;
}

void convert(int num,int base)
{
	int rem=num%base;
	
	if(num==0)
		return;
	convert(num/base,base);
	
	if(rem<10)
		printf("%d",rem);	
	else
		printf("%c",rem-10+'A');
}

Output
