Entroduction to Generic Programming When implementing a swap function, we might write multiple overloaded versions: void Exchange(int& a, int& b) { int temp = a; a = b; b = temp; } void Exchange(char& a, char& b) { char temp = a; a = b; b = temp; } void Exchange(double& a, double& b) { doubl ...

Generic Programming Concepts How can we create a universal swap function that works with different data types? void Exchange(int& first, int& second) { int temporary = first; first = second; second = temporary; } void Exchange(double& first, double& second) { double temporary = first; first = second; sec ...

C++ templates enable code reuse by allowing type parametrization—defining logic that operates on unspecified types, which the compiler resolves into concrete implementations based on user-provided type arguments. This eliminates rigid type constraints in statically-typed C++ code. Compilers do not compile template definitions directly. Instead, ...

C++ templates enable writing generic code that works with different data types without rewriting the entire code for each type. They are broadly categorized into function templates and class templates. Function Templates Function templates provide a mechanism to define a generic function that can operate on different data types. The compiler ge ...
