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

Is there a way to specify how many characters of a string to print out using printf()?

The basic way is:

printf ("Here are the first 8 chars: %.8s\n", "A string that is more than 8 chars");

The other, often more useful, way is:

printf ("Here are the first %d chars: %.*s\n", 8, 8, "A string that is more than 8 chars");

Here, you specify the length as an int argument to printf(), which treats the '*' in the format as a request to get the length from an argument.

You can also use the notation:

printf ("Here are the first 8 chars: %*.*s\n",
        8, 8, "A string that is more than 8 chars");

This is also analogous to the "%8.8s" notation, but again allows you to specify the minimum and maximum lengths at runtime - more realistically in a scenario like:

printf("Data: %*.*s Other info: %d\n", minlen, maxlen, string, info);

The POSIX specification for printf() defines these mechanism
