Hello everyone. Currently, working on a program however i tried my first two programs using a driver but i still have an error. I'm not sure what the issue is. I'm new to c++ any assistance would be appreciated, Attached is the driver and 1 and 2 program. Thanks. Driver:

#include
using std::cout;
using std::cin;
using std::endl;

#include
//#include "Miscellaneous.h"

void showMenu();
int getResponse();

int main()
{

int response;


//NOTE: each time you finish writing a function and want to test it,
//uncomment the case within the switch that calls that function.
while ( ( response = getResponse() ) != 5 )
{
    switch( response )
    {

        //case 1: multiplication(); cout<<"\\n\\n"; break;
        //case 2: numberGuess(); cout<<"\\n\\n"; break;
        //case 3: printSquare(); cout<<"\\n\\n"; break;
        //case 4: calculatePayroll(); cout<<"\\n\\n"; break;
    }
    system("pause");
}

cout<<"\\n\\nThank you and have a nice day!\\n\\n";

return 0;

}

void showMenu()
{

system("cls");
cout<<"\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\\n";
cout<<"\* Press 1 to do multiplication    \*\\n";
cout<<"\* Press 2 to play number guessing \*\\n";
cout<<"\* Press 3 to print a square       \*\\n";
cout<<"\* Press 4 to calculate payroll    \*\\n";
cout<<"\* Press 5 to Quit                 \*\\n";
cout<<"\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\\n";
cout<<"=====> ";

}

int getResponse()
{
int response;
showMenu();
cin>> response;

while( response < 1 || response > 5)
{
    showMenu();
    cin >> response;
}
return response;

}
1 CASE: MULTIPLICATION

Maybe if you explained what the error is, and where it occurs, we could make some suggestions.

I've fixed you program for you, in order to perform correctly the multiplication case. All the other ones are up to you.

#include using std::cout;
using std::cin;
using std::endl;

#include
#include void showMenu();
int getResponse();

void correctMessage( );
void incorrectMessage( );
void multiplication( );

int main()
{
int response;

//NOTE: each time you finish writing a function and want to test it,
//uncomment the case within the switch that calls that function.
while ( ( response = getResponse() ) != 5 )
{
switch( response )
{
case 1:
multiplication(); cout<<"\n\n";
break;
//case 2: numberGuess(); cout<<"\n\n"; break;
//case 3: printSquare(); cout<<"\n\n"; break;
//case 4: calculatePayroll(); cout<<"\n\n"; break;
default:
if ( response < 5)
cout << "sorry, not yet implemented\n\n";
break;
}
}
cout<<"\n\nThank you and have a nice day!\n\n";
return 0;
}

void showMenu()
{
system("cls");
cout<<"***********************************\n";
cout<<"* Press 1 to do multiplication *\n";
cout<<"* Press 2 to play number guessing *\n";
cout<<"* Press 3 to print a square *\n";
cout<<"* Press 4 to calculate payroll *\n";
cout<<"* Press 5 to Quit *\n";
cout<<"***********************************\n";
cout<<"=====> ";
}

int getResponse()
{
int response;
showMenu();
cin>> response;

while( response < 1 || response > 5)
{
showMenu();
cin >> response;
}
return response;
}

void correctMessage( void )
{
cout << "Very good!\n";
}

void incorrectMessage( void )
{
cout << "No. Please try again.\n";
}

void multiplication( void )
{
int x, y, response = 0;
srand( time( 0 ) );

while ( response != -1 )
{
x = rand() % 10;
y = rand() % 10;
cout << "How much is " << x << " times " << y<< " (-1 to End)? "; cin >> response;
while ( response != -1 && response != x * y )
{
incorrectMessage();
cin >> response;
}
if ( response != -1 )
{
correctMessage();
}
}
}
