Global Matrix

[eternalLearner]

hi need to code a global matrix,whose size can only be defined at the run time.please tell me how to do the same ?
thanks in advance

You will have to dynamically allocate the memory using pointers. The real question is, why do you need to use a global variable? 99/100 times, when I've programmed, I've never needed to use a global variable.

You will need to dynamically assign the size of the array.

In C you use a global pointer and you do the allocation in main().

In C++ you use a global object.

The larger question is why global in the first place???
