#include // TODO: Create a function template that squares a value // - Returns value * value // - The compiler will create different instantiations for each type used // Example output: // 25 // 12.25 // 100 // TODO: Create a function template that returns the absolute value // - If value < 0, return -value; otherwise return value // - Test with explicit type specification to control instantiation // Example output: // 42 // 7.5 // 1000000 // TODO: Create a function template that adds two values // - Returns a + b // - Observe how template argument deduction creates instantiations // Example output: // 30 // 6 // 300 // TODO: Create a function template that returns the larger of two values // - Multiple calls with same type reuse the same instantiation // - The compiler only generates code once per unique type // Example output: // 10 // 3.14 // 100 // 10.1 int main() { // Implicit instantiation - compiler deduces type std::cout << square(5) << '\n'; std::cout << square(3.5) << '\n'; std::cout << square(10L) << '\n'; // Explicit instantiation - we specify the type std::cout << absolute(-42) << '\n'; std::cout << absolute(-7.5) << '\n'; std::cout << absolute(-1000000L) << '\n'; // Template argument deduction std::cout << add(10, 20) << '\n'; std::cout << add(3.14, 2.86) << '\n'; std::cout << add(100L, 200L) << '\n'; // Multiple instantiations (same type reuses existing) std::cout << max(5, 10) << '\n'; std::cout << max(3.14, 2.71) << '\n'; std::cout << max(100, 50) << '\n'; std::cout << max(9.9, 10.1) << '\n'; return 0; }
