c语言break和continue用法

#include <stdio.h>

int main(){

int i=1, sum=0;

while(1){ 

  //循环条件为死循环

  sum+=i;i++;if(i>100) break;

}

printf("%d\n", sum);return 0;}

#include <stdio.h>

int main(){

    char c = 0;

    while(c!='\n'){  //回车键结束循环

        c=getchar();

        if(c=='4' || c=='5'){  //按下的是数字键4或5

            continue;  //跳过当次循环，进入下次循环

        }

        putchar(c);

    }

    return 0;

}
