Reverend Jim 4,968 Hi, I'm Jim, one of DaniWeb's moderators. Moderator Featured Poster
Based on the little information you provided, your code does exactly what it says it does. Of course, that's likely not what you wanted it to do. Perhaps if you provided a little more information like:
- What is this code supposed to do
- What is it actually doing
- What error messages (if any) are you getting
- Does it compile
In case anyone (other than the OP) is inclined to respond "it's obvious what the code is supposed to do", that may be the case but the OP has not gone to much effort in seeking help. I certainly would not take my car to a mechanic and say "fix this" without describing the problem.

Sorry for the little infos. The purpose of this code is for searching, editing, adding, deleting, displaying, saving and shuffling the variables in an array. It promps the user to input its desired array size then input the elements/values they want and then stored it an array.
I doesn't have syntax errors.
It runs, but suddenly it tell exe has stopped working. I also tried this code in other laptops but does the same, runs but suddenly the console stopped working. Then I tried it on my phone. It works it definitely works but inlaptops it doesn't. theres one laptop that this code works its on my friends'. What could be the possible problem? it is a human error? in my code? in the laptops?
