Hello.

I am a beginner programmer and I am writing out a simple program, for a start. But the compiler (codeblocks) showed an error and so I am here to ask for help =)

Here's the code -

Code:
#include <iostream>

using namespace std;


int mult ( int a, int b );


int main()
{
    int x;
    int *p;
    int a;
    int b;


    p = &x;
    cout << "Please input a number: ";
    cin >> x;
    cin.ignore();


    cout << "\nYou have entered " << *p;
    cin.get();


    cout << "\nPlease enter two numbers to be added up: ";
    cin >> a >> b;
    cin.ignore();
    cout << "\nThe result is - " << mult ( a, b );


    cin.get();
}


int mult ( int a, int b )
{
    return a + b;
}


void Add()
{
    cout <<"\n Add 100";
}
void Subtract()
{
    cout <<"Subtract by 50";
}
void Multiply()
{
    cout <<"Multiply by 100";
}
void Divide()
{
    cout <<"Divide by 10";
}
    int input;


    cout<<"1. Add\n";
    cout<<"2. Subtract\n";
    cout<<"3. Multiply\n";
    cout<<"4. Divide\n";


    cin>> input;


    switch (input) {
    case 1:
        Add();
        break;
    case 2:
        Subtract();
        break
    case 3:
        Multiply();
        break
    case 4:
        Divide();
        break
    default:
        cout<<"Input not recognized. Quitting now\n";
        break;
    }
    cin.get();
}
And here's the error -

Line 53, 54 and 55
expected constructor, destructor or type conversion before << token

I need help to fix this error. Perhaps anyone has the freetime to teach me a thing or two?

Reply ASAP please
