First-week pairing programming arithmetic

Project requirements: The program randomly generates arithmetic calculation questions, and after the user fills out the answer to determine the correct answer.

Pair member: Li Qiao

Task assignment: The algorithm thought and the main function adopted by Li Qiao are responsible for.

I am responsible for some code input and results testing.

Roughly divided into two modules: 1. Randomly generated arithmetic calculation questions 2. Determine the correct and correct input answers

The main code is as follows:

1#include <stdio.h>2#include <string.h>3#include <time.h>4#include <stdlib.h>5 intMain ()6 {7       Charstr[]="+-*/";8Srand (Time (0));9       intres[Ten];Ten        for(inti =0; i<=9; i++) One       { A             intA = rand ()% -+1; -             intb = rand ()% -+1; -             intc = rand ()%4; the             if(c==3) -             { -                  while(a%b) A = rand ()% -+1, B = rand ()% -+1;  -             } +printf"%d%c%d\n", a,str[c],b); -             if(c==0) Res[i] = a +b; +             Else if(c==1) Res[i] = A-b; A             Else if(c==2) Res[i] = A *b; at             ElseRes[i] = A/b; -       } -       ints[Ten]; -printf"Please enter an answer separated by a space \ n"); -        for(intI=0; i<=9; i++) -       { inscanf"%d",&s[i]); -       } to        for(intI=0; i<=9; i++) +       { -           if(s[i]!=Res[i]) the           { *printf"question%d is wrong, the correct answer is%d\n", i+1, Res[i]); $            }Panax Notoginseng       } -       return 0; the}

The results of the operation are as follows:
