C Basic Declarations and Expressions: Exercise-24 with Solution

Write a C program that reads two integers and checks whether they are multiplied or not.

Pictorial Presentation:

C Programming: Reads two integers and checks whether they are multiplied or not

C Code:

#include <stdio.h>

int main() {
	int  x, y;
    printf("\nInput the first number: "); 
    scanf("%d", &x);
    printf("\nInput the second number: ");
    scanf("%d", &y);
  
    if(x > y) 
	{
		int temp;
		temp = x;
		x = y;
		y = temp;
	}
	
	if((y % x)== 0) 
	{
		printf("\nMultiplied!\n");
	} 
	else 
	{
		printf("\nNot Multiplied!\n");
	}
	
	return 0;
}

Sample Output:

Input the first number: 5                                              
                                                                       
Input the second number: 15                                            
                                                                       
Multiplied!

C Programming: Tips of the Day

What does (x ^ 0x1) != 0 mean?

The XOR operation (x ^ 0x1) inverts bit 0. So the expression effectively means: if bit 0 of x is 0, or any other bit of x is 1, then the expression is true.

Conversely the expression is false if x == 1.

So the test is the same as:

if (x != 1)

and is therefore (arguably) unnecessarily obfuscated.
