Templates

What are Templates?

💡 Note

Templates let you write generic code that works with any data type — one function/class for int, double, string, etc.

Function Template

C++

#include <iostream>
using namespace std;
template <typename T>
T maximum(T a, T b) { return (a > b) ? a : b; }
int main() {
    cout << maximum(3, 7) << "\n";       // 7
    cout << maximum(2.5, 1.5) << "\n";   // 2.5
    return 0;
}

Output:
7 2.5

Summary

Templates write type-independent code using template <typename T>.
One template works for many data types.
