Programming Example
Program to find the simple interest.
In this program you will learn how to find the simple interest. Lets first understand the concept of simple interest then we will write our code.
Information & Algorithm
- The initial money borrowed or lent out for a certain period is called the Principal (P).
- The extra money paid for using others money is called Interest.
- The total money paid back to the lender at the end of the time period (T) for which the principal is borrowed is called an amount (A).
- The rate at which the interest has to be paid per annum is called rate of interest (R).
Program Code
#include"stdio.h"
void main()
{
// variable declaration
int p,r,t,si;
// take values from user
printf("enter principle, Rate of interest & time to find simple interest:\n ");
scanf("%d%d%d",&p,&r,&t);
// Calculate simple interest
si=(p*r*t)/100;
// Print result
printf("simple intrest= %d\n",si);
}
Output
enter principle, Rate of interest & time to find simple interest:
1000 8 2
simple intrest= 160

How to learn from this program
First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
Practice suggestion
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
