Your was the first issue and part of the third issue of the four I pointed out.

@yusufabi It may seem a bit rough, but I recommend reading this paper about asking questions in technical forums. It will help both in asking and in responding to the replies you ha…

You need to determine what you want, genome recombination (accurate or not doesn't matter) or a way two recombine 2 dimensional arrays? Are they fixed to 2 fields each or do you consider to have N fields in the second array? This makes a huge difference and you should learn to ask for what you want…

its not erasing last element of vector. i would like to erase enemies from my class this is my problem

Please explain in words how this erase code works.

for (int i = 0; i<7; i++) { for (int j = 0; j<7; j++)

ugh, then at least optimize to avoid redundant tests:

for (int i = 0; i<7-1; i++)
for (int j = i+1; j<7; j++) {:)}

Thanks for pointing that out. It has since been fixed.  ?
