Help me out?

Why do I get this error in Visual studio but not when i try to run the code on an online C compiler, I even tried submitting my code through Matrix and it works completely fine. Can anyone help me out?

Did you try saving it then turning off vs code then turning it on?

VS uses its own compiler, online is probably using gcc, which is the same as matrix

I would check where wishlisiItems is defined

int x;
printf("Enter a number: ");
scanf("%d", &x);
double y[x];

int x;
printf("Enter a number: ");
scanf("%d", &x);
double y[x];

This is legal in C, his compiler is saying its not At least with gcc

Yea, I am assuming it can't see wishListItems

gr8b8m8_2l8•13mo ago

Error is saying expression must be a constant value Actually If those are not inside a function that error is correct

wishListItems is defined at the top using int like this: int wishListItems;

And do you set it to a value anywhere?

smb•13mo ago

nope no value but we enter in when we run the code
