C++ Program to Calculate Simple Interest Using Inline Function

#include <iostream>
using namespace std;

inline float simpleInterest(float p, float r, float t)
{
    return (p * r * t) / 100;
}

int main()
{
    float p, r, t;
    cout << "Enter principal, rate and time: ";
    cin >> p >> r >> t;

    cout << "Simple Interest = " 
         << simpleInterest(p, r, t);
    return 0;
}
  

📘 Explanation:

This program demonstrates the use of an inline function in C++ to calculate Simple Interest.

The inline function simpleInterest() takes three parameters: principal amount (p), rate of interest (r), and time period (t). It calculates simple interest using the formula:

Simple Interest = (P × R × T) / 100
  

Since the function is small and frequently used, declaring it as inline helps improve performance by reducing function call overhead.

🧾 Sample Output:

Enter principal, rate and time:
1000 5 2
Simple Interest = 100
