C语言之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：导致最内层的封闭循环或者switch立刻退出；

continue：导致for，while，或者do循环的下一个循环开始执行。continue只用在循环中，不用在switch中。一个循环中switch中的continue会导致下一个循环。

#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;
}

输出：0 1 2 3 4 5 6 7 8 9

break只是退出了switch，执行了后面的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;
}

输出：0 1 2 3 4 6 7 8 9

continue直接执行下一个for循环，没有执行printf
