Enter a number and show its factor

In this example we are going to explain how you can enter a number and how you can find its factor.

To enter a number we first define an integer variable then use a scanf("%d",&a) method .This method is used to take input from keyboard. We can enter number, float or character by using this method. We have use %d,%f and %c reactively at place of first argument. The second argument is used to store the value at variable location.

To find factor we are using for loop which iterate from 1 to a .We are checking the modulo of a and value from 1 to a. If it return zero then this mean the it is factor of a and print it.

/* Enter a number and show its factor */
#include<stdio.h>
#include<conio.h>
void main()
{
int a,i;
clrscr();
printf("Enter a number\t");
scanf("%d",&a);
for(i=1;i<=a;i++)
{
if(a%i==0)
printf("\nFactor of the number is\t=%d",i);
}
getch();
}
