C Language Programming skills (note points)

Assume that all variables are already defined. Most symbols are full-width symbols, and the code cannot be copied directly, only for reference.

1. When comparing two data, try to put known quantity in front. For example: a = 2;scanf ("%d", &b); if (a > B) {...}; It is not recommended to write if (b > a) {...}

2. The program exports as little as possible, that is, the return statement as little as possible. For example: Find the maximum number of a,b,c, only the last return maximum.

3. About scanf ("%d%d", &a,&b), two%d can be added to a variety of symbols, such as%d,%d, the middle of a comma, which means that the program executes to this statement, the input of the two data between the comma (23,45), proposed to write%d%d, Without any symbols in the middle.
