编写一个c程序实现小学数学测试题

Question

题目：小学数学测验题生成程序 实验要求： 从键盘输入题目数量N（3<N<=50），随机生成N道小学数学计算题，要求至少自定义2个函数，实现如下功能： 按照生成的顺序输出生成的N道题目，至少包含加、减、乘、除法运算各一题，且每种运算题目数量随机，总数为N； 模拟两个或更多个学生做该测验题，分别输出每个学生的做题情况（包括题目，结果以及对错的判定）、总的得分率以及加减乘除每种类型题目的得分率。 注意事项： a) 不考虑混合运算，加减乘除运算的题目每道题只考虑两个操作数情况即可；如x+y、x-y、x*y、x/y形式； b) 任何运算的结果必须是大于等于0且小于100； c) 除法运算结果不能出现小数，只能写商几余几的形式（如5/2答案只能是商2余1，而不能是2.5；输入输出时如何表示商2余1自定，比如可以直接输出2 1表示。），且被除数需要大于除数。 提示：生成随机数函数为rand和srand函数。
