continue与break

1.continue语句，1至20内奇数累加和

#include<iostream>using namespace std;void main(){    int i=0;    int sum=0;    while(i<20){        i++;        if(i%2==0)            continue;        else            sum+=i;        cout<<"当前i的值为"<<i<<" sum的值为"<<sum<<endl;    }    system("pause");}

 

2.break语句，1至20累加和

#include<iostream>using namespace std;void main(){    int i=0;    int sum=0;    while(i<50){        i++;        if(i==21)            break;        else            sum+=i;        cout<<"当前i的值为"<<i<<" sum的值为"<<sum<<endl;    }    system("pause");}
