英语六句作文常用语句【三】
C语言while、do-while、for循环课程5
课程3中，提到C语言基本语句分为：数据定义语句，数据处理语句
数据处理语句又可分为：表达式语句，函数调用语句，空语句(;，复合语句，流程控制语句。
流程控制：指程序代码执行的顺序。流程的分类：顺序、选择、循环。
C语言的循环结构通过三种语句来实现，即while、do-while、forWhile语句的一般形式while(循环条件表达式循环体语句；
功能：当循环条件表达式为真，执行循环体语句，执行完了，再判断条件表达式是否为真，为真，则再执行，直到条件表达式为假时，退出while循环。
实例1：用while语句求1~100的累加和。
#include//C语言编译预处理命令，文件包含为stdio.h
voidmain(//至少有一个用main(命名的主函数，返回值为void无值类型{
inti=1,sum=0;/*初始化循环，定义变量i和累加器sum，定义和之前，累加器清零*/
while(i<=100
{
sum+=i;//sum+=i是一个复合赋值运算符，等价于sun=sun+i;i++;
}
printf("1+2+3+...+100=%d ",sum;//输出十进制数，1加到100累加器的和}
MicrosoftVisualC++6.0运行结果
使用while循环时，一定要对循环条件表达式中出现的变量提前赋值，并在循环体内修改有关变量的值，以使循环能趋于终止。
While循环为当型循环，do-while循环也叫直到型循环。
do-while语句的一般形式为：
do
{
循环体语句}while(
循环条件表达式
实例2:用do-while编制一个求n!的程序，n的值由键盘输入。
#include
voidmain(
{inti=1,n,p=1;
printf("请从键盘输入一个数，进行连乘积: ";
scanf("%d",&n;
do
{p=p*i;
i++;
}while(i<=n;
printf("连乘积的结果为p=n!：%d ",p;
}
分析：此程序，先定义三个变量i、n、p,p从p乘1开始执行，再i进行自增1，循环体中的语句执行完毕后，判断while的循环条件表达式，当i自增1为2时，看2是否<=输入的n值，若为真，则继续返回do循环，直到i自增的值比n大，则退出循环。
do-while主要用于人机交互，do-while循环是先执行后判断，do里面的循环体至少被执行一次。区别于while是先判断循环条件表达式，后执行。
for循环也叫步长型循环
一般格式：for(表达式1；表达式2；表达式3循环体语句；
功能:先执行表达式1，再执行表达式2，如果表达式2的值为真，就执行循环体语句，最后执行表达式3.完成一次循环后，从表达式2执行，直到表达式2为假，退出循环。
实例3：参考实例1，用while求1~100的累加和，现在用for语句求1~100的累
加和。
#include
intmain(void
{
inti;intsum=0;
/*初始化循环，定义变量i
和累加器sum，定义和之前，累加器清零*/
for(i=1;i<=100;i++
{
sum=sum+i;
}
printf("sum=%d ",sum;
return0;
}
实例4：爱因斯坦的`阶梯问题：有一个长阶梯，若每步上2阶，最后剩1阶；若每步上3阶，最后剩2阶；若每步上5阶，最后剩4阶；若每步上6阶，最后剩5阶；只有每步上7阶，最后刚好一阶也不剩。请问该阶梯至少有多少阶。编写一个C程序解决该问题。
#include
main(
{intx;
for(x=7;;x+=7
if(x%3==2&&x%5==4&&x%6==5
break;
printf("Thenumberoftheladdersis：%d ",x;
}
分析：发现x一定是7的整数倍，可以依次递增地求出7的整数倍的值（7*1、7*2、7*3……），每求出一值，就用该值与2、3、5、6进行取模运算，最先得到的满足上述5个方程式的x值即为本题的答案。
用while语句，简单快速实现爱因斯坦的阶梯问题
#include
intmain(
{
inti=1;/*i为所设的阶梯数*/
while(!((i%2==1&&(i%3==2&&(i%5==4&&(i%6==5&&(i%7==0
++i;/*满足一组同余式的判别*/
