Write a C Program to Find Simple Interest.
In this article, we will calculate the simple interest without using structures and functions. Simple interest can be calculated using the formula.
Simple Interest (SI) = (Principal * Rate * Time) / 100
Where:
Principal: The initial amount of money.
Rate: The rate of interest per annum.
Time: The time period in years.
Here's a C program to Find Simple Interest:
#include<stdio.h>
#include<conio.h>
void main()
{
// Declare variables to store principal, rate, and time
float principal, rate, time;
// Read input from the user
printf("Enter the principal amount: ");
scanf("%f", &principal);
printf("Enter the rate of interest (in percentage): ");
scanf("%f", &rate);
printf("Enter the time period (in years): ");
scanf("%f", &time);
// Calculate simple interest
float simpleInterest = (principal * rate * time) / 100;
// Display the result
printf("Simple Interest: %.2f\n", simpleInterest);
}
- We first declare three variables principal, rate, and time to store the input values.
- We then use printf and scanf functions to get these values from the user.
- After obtaining the values, we calculate the simple interest using the formula and store it in the variable simpleInterest.
- Finally, we display the result using printf with %.2f to print the result up to two decimal places.
Output:
