Your problem is that a double pointer isn't the proper way to get access to a two-dimensional array, as the anonymous poster said. There's two very easy ways to fix this: You could either just index tester instead of p, as in tester[outer][inner].setnum(), or if you want to use pointers, then use some pointer math for the loops:
#include using namespace std; class test { int num; public: void setnum(int n) { num = n; cout << "Test! " << n; } int getnum() { return num; }};int main() { test tester[5][5], *p; int inner, outer; for (outer = 0, p = (test *) tester; outer < 5; outer++) for (inner = 0; inner < 5; inner++, p++) { p->setnum(outer+inner); } for (outer = 0, p = (test *) tester; outer < 5; outer++) for (inner = 0; inner < 5; inner++, p++){ cout << p->getnum() << "\n"; } return 0;}
this works because of the way two-dimensional arrays are stored linearly in memory.

It seems to crash on the second loop of the first nested for loop (inner), when putting the numbers in test.num.
