switch在循环中时 可以用continue替代break

#include <stdio.h>
#include <stdlib.h>


int main()
{
    int x;
    while(scanf("%d",&x))
    {
        switch(x)
        {
            case 1:
                printf("case 1\n");
                break;
            case 2:
                printf("case 2\n");
                continue;
            default:
                break;
        }
    }

    return 0;
}
