The core of this question is to find the area of any polygon. We can use cross product to calculate. Take any one point and take two adjacent points clockwise to form two vectors with this point for cross product. All cross-border products obtained

1. Why is a template class used in C ++? (1) It can be used to create a data structure with dynamic growth and reduction. (2) It is type-independent and therefore highly reusable. (3) It checks the data type during compilation rather than during

Use DFS to mark the adjacent @ characters and count the number of blocks. [Cpp] # include int m, n; char map [105] [105]; int dir [8] [2] = {-1,-1,-1, 0,-1, 1, 0,-1, // defines eight direction arrays 0, 1, 1,-1, 1, 0, 1, 1}; void dfs (int x, int y)

Preface I caught a cold this weekend and never wrote a program. I got a question and practiced it. It is strange that this question can only be used as a global array. Passing parameters will always cause problems and gdb has not been debugged, this

When talking about GDB, we can't help but turn to its powerful functions. Among all the debuggers I have used, this is really a powerful debugging tool. Today I will talk about the simple usage of GDB. GDB is a powerful UNIX program debugging tool
