okay...i've got another wired counting problem, this time it's about rectangles! gotta find the minimum number of lines to divide a rectangle into squares! i went for...ehh well a dumb idea of cutting the max square off, and cutting the little ones recursively, but... doesn't always work. you're given the …

The requirements are actually simple, just asking to sort a few, say 10, 20 or so, intergers in ascending order. However, array and pointers are not allowed to be used, and just the fundamental knowledge about flow control are permitted. The hints are as follows: 1. Initialize a variable F …

I create the simple template structure like this [CODE] #include <iostream> template <class info> struct box { info data; }; int main() { box<int> b1; b1.data = 1; std::cout<<b1.data; return 0;typedef box square; } [/CODE] Now i want to use the typedef for this template structure.
