C++ Program to Convert Celsius to Fahrenheit Using Inline Function

#include <iostream>
using namespace std;

inline float celsiusToFahrenheit(float c)
{
    return (c * 9 / 5) + 32;
}

int main()
{
    float c;
    cout << "Enter temperature in Celsius: ";
    cin >> c;

    cout << "Fahrenheit = " 
         << celsiusToFahrenheit(c);
    return 0;
}
  

📘 Explanation:

This C++ program converts temperature from Celsius to Fahrenheit using an inline function.

The inline function celsiusToFahrenheit() applies the formula:

Fahrenheit = (Celsius × 9 / 5) + 32

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