华电大学c课件第四讲字符型数据例1#include<stdio.key:if(x>0)while（i<5);标号:if(表达式){inti=0,a=8;voidmain(){inti,s;i++;}t1=getchar();switch(65+k)#include<iostream.{inti=1,s=0;voidmain()cout<<a+1;t=getchar();voidmain()例1#include<stdio.scanf("%d",&n);举例循环结构的概念if语句和goto语句构成循环if语句和goto语句构成循环while循环voidmain()putchar(c1);{inti,s;t1=getchar();例1#include<stdio.while(i<=100);voidmain()printf(“%c\n”,t1);#include<iostream.voidmain()a1=c1-32;voidmain()专门用于字符输入/出的函数例4输入字符，若该字符是大写字符，就变成相应的小写字符；while(i!=0)voidmain()voidmain()例2编程序，计算s=1+2+3+……+100dowhile和while的区别for循环感谢观看
