C语言while&dowhile语句#include<stdio.h>voidmain(){inti=1;while(i<1){printf(“执行while语句\n”);}do{printf(“执行do...while语句\n”);}while(i<1);}使用while循环编写一段代码计算下列算式计算1！+2！+3！+……+10!#include<stdio.h>voidmain(){inti=1;intt=1;ints=0;while(i<=10){t=t*i;s=s+t;i++;}printf("%d\n",s);}练习一：编写代码完成下面要求的功能#include<stdio.h>#include<stdlib.h>voidmain(){intx,y,z;intscore=0;x=rand()%100+1;y=rand()%100+1;printf("%d+%d=",x,y);scanf("%d",&z);while(x+y==z){printf("回答正确！继续听题！\n");x=rand()%100+1;y=rand()%100+1;printf("%d+%d=",x,y);scanf("%d",&z);score+=10;}printf("回答错误！考试结束！\n");printf("你的最终得分是：%d\n",score);}循环的嵌套#include<stdio.h>voidmain(){inti=1;//定义整数型变量i并初始化为1intj;//定义整数型变量jwhile(i<=5){//当i<5是执行循环体j=i;//观察1.每一行的第一个数和行数相等2.之后的数是递减while(j>0){printf("%d",j);j--;}printf(“\n”);//一行输出完毕后换行i++;}}
