比较原始的学校出题系统，用C语言编写的。有对试题的选择出题，增，删，改。执行方法：1.运行init_examanation.2.运行newbuilding.3.运行run_examanation。程序中可以运行。不过为了避免一点不会的人拿来就用，所以加了一点“BUG”。纯属蓄意-primitive out that the school system, using the C language. Have the right to choose questions that, by deleting replaced. Means of implementation : 1. init_examanation.2 operation. newbuilding.3 operation. Win OK run_examanation. Procedures can run. But no one o'clock in order to avoid the use on the case, plus a little "Bug." Purely deliberately
