有關continue與break的belabela....

先來兩句科學的定義：

continue是跳過某一次小循環；

break是跳過整段循環；

舉個栗子：

#include<bits/stdc++.h>
using namespace std;
int main()
{
for(int i=1;i<=3;i++)
   for(int j=1;j<=3;j++)
      {
      if(i==j) continue/break;
      cout<<'*';
      }
}

輸出：當是continue時：******

           當是break時：***

解釋一下：

當是continue時，程序是這樣運行的：i=1,j=1，跳過j=1的這一次小循環

                                                             i=1,j=2，輸出

                                                             i=1,j=3，輸出

                                                             i=2,j=1，輸出

                                                             i=2,j=2，跳

                                                             i=2,j=3，輸出

                                                             i=3,j=1，輸出

                                                             i=3,j=2，輸出

                                                             i=3,j=3，跳

當是break時，程序是這樣運行的：i=1，j=1，跳出這層循環
                                                             i=2，j=1，輸出
                                                             i=2，j=2，跳 
                                                             i=3，j=1，輸出
                                                             i=3，j=2，輸出
                                                             i=3，j=3，跳
