Question

I am writing a program to do some analysis on DNA sequences.
Everything works fine except for this thing.
I want to declare a 2D array of size m*n where m and n are read from an input file.
Now the issue is that if m and n goes too large. As an example if m = 200 and n = 50000
then I get a seg fault at the line where I declare my array.

array[m][n];

Any ideas how to overcome this. I do need such an array as my entire logic depends on how to process this array.

Answer 1

Probably you are running out of stack space.
Can you not allocate the array dynamically on heap using malloc?
