【C++】break與continue

簡單地解釋

break：跳出循環，不再執行循環體。

continue：結束（跳過）本次循環，繼續執行循環體。

DEMO

/*breakDemo*/
#include <iostream>
using namespace std;
int main()
{
	for (int i=0; i<10; i++)
	{
		cout << "i = " << i << endl;
	}

	cout << "break..." << endl;
	for (int i=0; i<10; i++)
	{
		if (i == 5)
		{
			break;
		} 
		else
		{
			cout << "i = " << i << endl;
		}
	}
}

/*continueDemo*/
#include <iostream>
using namespace std;
int main()
{
	for (int i=0; i<10; i++)
	{
		cout << "i = " << i << endl;
	}

	cout << "continue..." << endl;
	for (int i=0; i<10; i++)
	{
		if (i == 5)
		{
			continue;
		} 
		else
		{
			cout << "i = " << i << endl;
		}
	}
}

有圖有真相

當然，在JAVA中的結果是一樣的。
