C語言之break和continue

break：cause the innermost enclosing loop or switch to be exited immediately.

continue: cause the next iteration of the enclosing for, while, or do loop to begin. The continue statement appliesonly to loops, not to switch. A continue inside a switch inside a loop causes the next loop iteration.

break：導致最內層的封閉循環或者switch立刻退出；

continue：導致for，while，或者do循環的下一個循環開始執行。continue只用在循環中，不用在switch中。一個循環中switch中的continue會導致下一個循環。

#include <stdio.h>

/* test the break and continue */
int main()
{
    int i;
    for (i = 0; i < 10; i++)
    {
        switch(i)
        {
            case 5:
                break;
        }
        printf("%d", i);
    }
    return 0;
}

輸出：0 1 2 3 4 5 6 7 8 9

break只是退出了switch，執行了後面的printf

#include <stdio.h>

/* test the break and continue */
int main()
{
    int i;
    for (i = 0; i < 10; i++)
    {
        switch(i)
        {
            case 5:
                continue;
        }
        printf("%d", i);
    }
    return 0;
}

輸出：0 1 2 3 4 6 7 8 9

continue直接執行下一個for循環，沒有執行printf
