2D Array for QuarterlySales

vmay93 (4)
How do I create a getInput function, a calcTotal function and a displayResults function. When the purpose of getInput is to prompt the user for input and assign values to the 2D array. The purpose of the caclTotal function is to process the 2D Array and accumulate the total sales. The purpose of the displayResults function is to display the entire 2D array for quarterly sales as well as the total sales. The main function should consist of variable declarations and function calls. Do not use global variables. Pass the data through functions parameters or value returning f? Please help.

        cout << "The total sales for the company are: $";
        cout << totalSales << endl;
        cout << "Total sales is: " <<total;
        
    }
    
    return;
    
}


Here is how I ended up doing it but I get an error on my getInput function. Why is that?
