Here we will write a program to calculate Simple Interest in C++, everyone is familiar what simple interest is.
Simply, Simple Interest = Principle x Time x Rate divided by 100 or
S. I. = PxTxR/100
How program works:
- This program takes in the prinicipal, rate and time as a screen input from the user.
- The program is executed (run) 5 times using the ‘FOR’ loop.
- It calculates the simple interest using the formula I = PTR/100.
- The principal, rate, time and the simple interest are then outputted using the ‘cout’ command.
Program to calculate Simple Interest in C++:
#include <iostream> using namespace std; int main() { int x; float sinterest,principal,rate,time; for(x=4;x>=0;x--) { cout << "Enter the principal, rate & time : " << endl; cin>>principal>>rate>>time; sinterest=(principal*rate*time)/100; cout << "Principal = $" << principal << endl; cout << "Rate = " << rate << "%" << endl; cout << "Time = " << time << " years" << endl; cout << "Simple Interest = $" << sinterest << endl; } return 0; }
OUTPUT:
Principal = $1000 Rate = 5% Time = 3 years Simple Interest = $150
