Programming Example

Example about using functions:

// A value returned by a return statement in a function
#include <iostream>
using namespace std;
int funcRet1(void);

int funcRet2();
int funcRet3();

int funcRet4(int z); 

int main()
{

 int num = 4;
cout<<"Line 1: Value returned by funcRet1: "<<funcRet1()<<endl; // Line 1
cout<<"Line 2: Value returned by funcRet2: "<<funcRet2()<<endl; // Line 2
cout<<"Line 3: Value returned by funcRet3: "<<funcRet3()<<endl; // Line 3
cout<<"Line 4: Value returned by funcRet4: "<<funcRet4(num)<<endl; // Line 4
return 0;
}
int funcRet1()
{ 

 return 23, 45;                    //Only 45 is returned 

 }
int funcRet2()
{

 int x = 5; int y = 6;
return x, y;                            //Only the value of y is returned

 }
int funcRet3()
{ 

int x = 5; int y = 6;
return 37, y, 2 * x;                 //Only the value of 2 * x is returned

 }
int funcRet4(int z)
{

 int a = 2; int b = 3;
return 2 * a + b, z + b;           //Only the value of z + b is returned

 }
