You cannot simply change the size of the array by simply changing the dimensions at runtime - you need to allocate the memory dynamically with new. Best is usually to use the STL containers - they have their length property built in and can be easily resized.
The size of the arrays is set before main begins, when the program is compiled.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
