Functions in C++ are similar to methods in Java and functions in JavaScript / Python: They’re pieces of code that perform tasks They (optionally) take parameters They (optionally) return a value Here’s some functions: doubleareaOfCircle(doubler) { returnM_PI * r * r; } voidprintBiggerOf(inta intb) {

C++ Enhancements to Functions B Functions can be overloaded which means that you can define several different functions with the same name as long as the correct version can be determined by looking at the number and types of the arguments The pattern of arguments required for a particular function is called its signature

using namespace std; All the elements of the standard C++ library are declared within what is called a namespace the namespace with the name std So in order to access its functionality we declare with this expression that we will be using these entities This line is very frequent in C++ programs that use the standard library

programs begin their execution – In this case the main function takes no input arguments and returns an integer value – You can also declare the main function to take arguments which will be filled with the command line options given to the program // my first program in C++ #include int main {

Creating Functions in C/C++ Motivation There are many reasons to create functions for your programs A fragment of code that appears in your program in multiple places can be placed into a function de nition and replaced by a function call instead resulting in a smaller more maintainable program It is smaller because there are fewer lines of

In C++ there are two methods for parameter passing: Passing the value (call-by-value) This is denoted by just declaring the type and the name of the parameter Passing the memory location (call-by-reference) This is denoted by adding the symbol &next to the parameter type void p(int x int& y) { } Call-by-valueCall-by-reference 15
