Problem with Program

[jude6363jr]

So I have a program in class that I believe in my mind everything is correct but I'm getting a bunch of errors and I'm not sure why...


This is the format: Write a program that asks the user to enter 5 integers and store them in an array. Then multiply each integer by 2 and put the answer back into the array. Finally, report the ending values back to the user.

Your program must:

Use a Loop structure to ask the user for the integers and store them in the array.
Use another Loop structure to multiply each integer by 2 and put the answer back into the array.
Use a third Loop structure to report the ending values back to the user

Put the code you need help with here.

}

for (int i = 0; i < 5; i++)
{
cout << endl << " Result " << i + 1 << " : " << numArray[i];
}
cout << endl;

result 0;

#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
    int numArray[5];

    cout << "Please enter 5 integers when prompted. " << endl;
    for (int i = 0; i < 5; i++)
    {
        cout << "Enter Integer " << i + 1 << " : ";
        // cin << numArray[i]; // *** 
        cin >> numArray[i] ;
    }

    for (int i = 0; i < 5; i++)
    {
        numArray[i] = numArray [i] * 2;
    }

    for (int i = 0; i < 5; i++)
    {
        cout << endl << " Result " << i + 1 << " : " << numArray[i];
    }
    cout << endl;

    // result 0; // *** return 0?
}

Or:

#include <iostream>

int main()
{
    const int N = 5 ; // avoid magic numbers
    int numArray[N]{}; // initialise to all zeroes (input may fail)

    std::cout << "Please enter " << N << " integers when prompted.\n" ;
    for (int i = 0; i < N; i++)
    {
        std::cout << "Enter Integer " << i+1 << " : ";
        std::cin >> numArray[i] ;
    }

    for (int i = 0; i < N; i++) numArray[i] *= 2;
    // or( for int& v : numArray ) v *= 2 ;

    std::cout << '\n' ;
    for (int i = 0; i < N; i++)
        std::cout << "numArray[" << i+1 << "] : " << numArray[i] << '\n' ;
}

1) Please use code tags when posting code, to make it readable:

2) If you have errors, TELL US WHAT THEY ARE.

Line 18: Your input operator is the wrong direction.
Should be:

    cin >> numArray[i] ;

Line 34: Should be:

    return 0;  //  Not result 0 

Line 35: You need a closing }

Please learn to use code tags correctly. You have an opening code tag, but apparently no closing code tag. A closing code tag is:
