Sample C Program To Calculate Simple Interest.

#include <stdio.h>
#include <conio.h>

void main()

{
    int p, r, t, si;
    clrscr();

    printf(" Enter principle, rate of interest & time to find simple interest: ");
    scanf(" %d %d %d",& p, & r, & t);

    si = ( p * r * t ) / 100;
    printf(" Simple interest = %d",si);
    getch();
}

OUTPUT:

Enter principle, rate of interest & time to find simple interest: 1000
2
5
Simple interest = 100

Sample C Program To Check Whether A Number Is Prime Or Not.

#include <stdio.h>
#include <conio.h>

void main()
{
    int i, n ,r=0;
    clrscr();
    printf(" Enter any no: ");
    scanf("%d",& n);

    for( i = 2; i < = n - 1; i++ )
    {
        if( n % i == 0)
            r = 1;
        break;
    }
    if( r == 0)
        printf(" Is prime ");
    else
        printf(" Not prime ");
    getch();
}

OUTPUT:

Enter any no: 8
Not prime
