Question

Alright, I just got finished making a function for some code I’m making, which will end up to be Conway’s Game of Life, but I am getting some unexpected errors.

Here is the code:

The errors are:

error: name lookup of ‘q’ changed for ISO ‘for’ scoping

error: expected initializer before ‘while’

Answer 1

The scope of q is limited to the for loop in which it was declared; any variables that are declared in the initialisation part of a for loop are treated this way.

You need to change the scope of q to last even after the for loop’s scope is gone. To do this, simply move

int q;

from in the for to above the for and change

for (int q = ...

to

for (q = ...

So your whole thing would look like

int q;
for(q=1; var2 == "Yes" && Seeds != Seeds; q++){

or

int q = 1;
for(; var2 == "Yes" && Seeds != Seeds; q++){

Also, this isn’t a new rule 🙂
