设计程序：利用循环编写程序，帮助小学生练习10以内加减法

#include <stdio.h>#include "time.h"#include "stdlib.h"int main(){    int iNumber1=0,iNumber2=0;    int iRightNum=0;    const int cTotalNum=10;        srand((int)time(0));    for (int n=0; n<cTotalNum; n++) {        int iResult=-1;        iNumber1=rand()%10+1;        iNumber2=rand()%10+1;        printf("Question NO.%d\n",(n+1));        printf("%d+%d=",iNumber1,iNumber2);        scanf("%d",&iResult);                if (iResult!=iNumber1+iNumber2) {            printf("Wrong!\n");        }        else{            printf("Right!\n");            iRightNum++;        }    }    printf("You have done %d questions, %d Right %d Wrong.\n",cTotalNum,iRightNum,(cTotalNum-iRightNum));    }
