Sum of two arrays

bobogolope (7)
I am reworking a previous post

http://www.cplusplus.com/forum/beginner/183495/

and have added the braces as suggested in the post but I am still receiving an error saying - void sum(int[],int[],int[],int[]) : cannot convert argument 4 from 'const int' to in[]

thanks for any help!

    }

The code, as posted, compiles and runs fine.

If you do change the type of fourth argument from int to int[], then calling the function with arraySize (a const int) is obviously an error, but the fourth argument should not be an array.

I copied your code exactly and it is working on my end? Try coping it and pasting it here: http://cpp.sh/


Array 1  +   Array 2  =   Array 3
      1  +        11  =        12
      2  +        12  =        14
      3  +        13  =        16
      4  +        14  =        18
      5  +        15  =        20
      6  +        16  =        22
      7  +        17  =        24
      8  +        18  =        26
      9  +        19  =        28
     10  +        20  =        30
     11  +        21  =        32
     12  +        22  =        34
     13  +        23  =        36
     14  +        24  =        38
     15  +        25  =        40
     16  +        26  =        42
     17  +        27  =        44
     18  +        28  =        46
     18  +        29  =        47
     20  +        30  =        50


My guess is there is something wrong with your setup/environment.
