Easy Templates & Generic Programming

Solve in Playground →

Problem Statement

Create a function template `add(T a, T b)` that takes two arguments of type `T` and returns their sum. In `main()`, read two integers and compute their sum using `add()`. Then read two doubles, compute their sum using `add()`, and print the results.

Input Format

Two space-separated integers, followed by two space-separated doubles.

Output Format

Print 'Int: [sum]' and 'Double: [sum]' on separate lines.

Constraints

None

Sample Input

5 10 2.5 3.5

Sample Output

Int: 15
Double: 6

Explanation

Function templates allow you to write a single generic function that works with any data type, avoiding repetitive code.

Starter Code

#include <iostream>

// Write your add function template here

int main() {
    int i1, i2;
    double d1, d2;
    // Read input and use add() template
    return 0;
}
