使用軟件——VS 2015
使用環境——C語言
早在上周我就開始使用C#語言做，由於最后一點問題而放棄，之后用C語言開始做，很順利，但是也碰到了一些問題，但是通過了百度文庫上的一些程序的借鑒和吳阿平同學的悉心指導最后還是解決了，主要是通過C語言實現能夠生成100以內的加減乘除題目，並且判斷使用者的答題是否正確。一開始的時候先會給使用者提供加減乘除四個選項，使用者選擇后會提示是一位數還是兩位數；之后使用者開始作答，之后之前的步驟一直循環，直到使用者不再使用。下面是程序代碼：
#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>

#include <time.h>
int add(int num1, int num2)//加法
{
return num1 + num2;
}
int subtraction(int num1, int num2)//減法
{
return num1 - num2;
}
int mul(int num1, int num2)//乘法
{
return num1*num2;
}
float divis(int num1, int num2)//除法
{
return ((int)(((float)num1 / num2) * 100 + 0.5)) / 100.0;
}
