Thread: some question asking for answer...

this

array[x][y]"\n";

should not compile...

You already asked the first question. If the answers were not good enough, may-be you should provide more information, for example show the code.

The second question is a bit too open-ended. It almost sounds like 'I've heard there are pointers and structs, should I bother to learn what they are?' Yes, you should and in the course you would probably find out yourself what they are good for.

ok cool anyway heres the code of the 2 file 1 project:

Code:

 #include <iostream>

using namespace std;

int main()
{ char act;

	do {
	cout<<"Please choose 1 of a mathematic actions. For multiplying press m, divide - d, add - a, and less - l ";
	cin>> act;
	int num, num1;
	switch (act) {
		case 'm':
	cout<<"Input 2 numbers to be multiplied(press enter after u choose the one and after the another) \n";
	cin>> num;
	cin.ignore();
	cout<<" x \n";
	cout<< endl;
	cin>> num1;
	cin.ignore();
	cout<<"= "<< num * num1;
	cin.get();
	break;
	return 0;
		case 'd':
			cout<<"Input 2 numbers to be divide\n";cin.ignore();
			cin>> num; cin.ignore(); 
			cout<<" : "; 
			cin>> num1; 
			cin.ignore();
			cout<<" = "<< num / num1;
			cin.get();
			break;
			return 0;
		case 'a':
			cout<<"Input 2 numbers u choose to add to each one\n";
			cin>> num; cin.ignore(); cout<<" + "; cin>> num1;
			cin.ignore();
			cout<<" = "<< num + num1;
			break;
			return 0;
			cin.get();
		case 'l':
			cout<<"Input 2 numbers to calculate the first minus the 2nd \n";
				cin>> num;
			cin.ignore();
			cout<<" - ";
			cin>> num1;
			cin.ignore();
			cout<<" = ";
			cin.ignore();
			cout<<num - num1;
			cin.get();
			return 0;
	} 
	} while(!(act == 'm' || act == 'd' || act == 'a' || act == 'l'));
}

this was my first 1, with the int main() now heres the 2nd:

Code:

 #include <iostream>

using namespace std;

int submain()
{

  int x;            // A normal integer
  int *p;           // A pointer to an integer
  p = &x;           // Read it, "assign the address of x to p"
  cin>> x;          // Put a value in x, we could also use *p here
  cin.ignore();
  cout<< *p <<"\n"; // Note the use of the * to get the value
  cin.get();
  return 0;

}

These are two separate programs? May-be it seems to you like one project but if both files are not part of the same program it is not the same project.

Replace submain with main and compile it as a separate program/project?
