In this post, I am going to show you how to write a simple C program to calculate the Simple Interest.
The formula to calculate the Simple Interest is,
Simple Interest = (Principal × Time × Rate ) / 100
Same formula we have to apply here, so let’s write the C program now,
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
#include <stdio.h> int main() { //declare variables float Principal, Time, Rate, SimpleInterest; //get the values from user printf("Enter the Principal Amount:"); scanf("%f", &Principal); printf("Enter the Rate of interest:"); scanf("%f",&Rate); printf("Enter the Time:"); scanf("%f", &Time); //find the Simple Interest SimpleInterest = (PrincipleAmount * Rate * Time)/ 100; //print the valuee printf("Simple Interest is :%.2f",SimpleInterest); return 0; } |
Let’s see a sample output of the above C program:
SI = (5000 × 2 × 8.2) / 100 = 820.00
Where,
P = 5000
T = 2 (yrs)
r = 8.2%
|
1 2 3 4 |
Enter the Principal Amount:5000 Enter the Rate of Interest:8.2 Enter the Time:2 Simple Interest is: 820.00 |
I hope this program is helpful for beginner C programming learners and school/college students.
