Print multiples of Unit Digit of Given Number in C Program
Input number N and fetch the unit digit of a given number and display the multiples of that number.
Input − N=326
Output − unit digit is 6 and its multiples are 2 and 3
Note − Unit digit of any number can be fetched by calculating the %10 with that number
For example − if your’re given with a number N and you need to find its unit digit that
you can use N%10 it will return you unit digit of number N
ALGORITHM
START Step 1 -> Declare start variables num, num2 and i Step 2 -> input number num Step 3 -> store num%10 in num2 to fetch unit digit Step 4 -> print num2 Step 5 -> Loop For i=2 and i<=num2/2 and ++i IF num2%i=0\ Print i End IF Step 6 -> End For Loop STOP
Example
#include<stdio.h>
int main() {
int num,num2,i;
printf("
enter a number");
scanf("%d" , &num);
num2=num%10; //storing unit digit in num2
printf("
unit digit of %d is: %d",num,num2);
for(i=2;i<=num2/2;++i) { //loop till half of unit digit
if(num2%i==0) { //calculate multiples
printf("
multiple of %d is : %d ",num2,i);
}
}
return 0;
}Output
If we run above program then it will generate following output
enter a number329 unit digit of 329 is: 9 multiple of 9 is : 3
