Write a Program to Find Simple Interest and Compound Interest.
Aim
This type of expression-based programs are supposed to be basic c-program, where user gives some inputs like for principal amount as p, time as n years and rate of interest as r. Finally, using the mathematical formula as expression will help in writing a C program to find the Simple Interest and Compound Interest.
Procedure/ Algorithm
Step-1: Start the program execution.
Step-2: Declare the variables p, n, r.
Step-3: Input the values for p, n, r.
Step-4: Calculate and print the values of simple interest.
OR
Step-5: Calculate and print the values of compound interest.
Step-6: Stop the program execution.
Hello WorldBlockHello World
// Program to calculate simple interest
#include<stdio.h>
#include<math.h>
int main()
{
int p,n;
float r;
printf("\nEnter the value of amount, number of years and Rate of interest:");
scanf("%d%d%f",&p,&n,&r);
float SI=(p*n*r)/100);
printf("\nThe simple interest is = %f",SI));
return 0;
} // end main
Output
Enter the value of amount, number of years and Rate of interest:
100

Program: Calculate the Compound Interest
// Program to calculate compound interest
#include<stdio.h>
#include<math.h>
int main()
{
int p,n;
float r;
printf("\nEnter the value of amount, number of years and Rate of interest:");
scanf("%d%d%f",&p,&n,&r);
float CI=p*pow((1+(r/100)),n)-p;
printf("\nThe compound interest is = %f",CI);
return 0;
} // end main
Output
Enter the value of amount, number of years and Rate of interest:
100
