我的朋友英语作文常用语句【四】

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*/
