Problem with Program

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.

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

http://www.cplusplus.com/articles/z13hAqkS/

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:
