FUNCTION PARAMETER IN C++
In C++, Parameters are a special kind of variable in C++ that are only used when a function is declared. The parameter can only be used in the function for which it was supplied. Each parameter that is declared in a list of parameters must be assigned a data type.
A function parameter in C++ is a variable that is set when a function is created. These variables either take or receive arguments when a function is called. The value that is supplied to a function upon its call in C++ is known as an argument.
They are 2 types of function parameters:
* Mandatory parameter
* Optional Parameter
Syntax:
void functionName(parameter1, parameter2, parameter3)
{
// code to be executed
}
Example:
#include <iostream>
#include <string>
using namespace std;
void myFunction(string fname)
{
cout << fname << "\n";
}
int main()
{
myFunction("Leo");
myFunction("Jessy");
myFunction("leeza");
return 0;
}
Output:
Leo
Jessy
Leeza
