A summary of the experiment of continue and break in C language

Pass the test , There's something about c What I learned , Write it down here . Attach code snippet ：

#include <stdio.h>
void main()
{
    int i;
    for(i=0;i<4;i++)
    switch(i)
    {
        default:printf("%d",i+1);
        case 1:printf("%d",i);
        case 2:printf("%d",i);
    }
}

The output is 100 11 2 433. When case There is no break All the following statements will be executed , If i stay case Are there in ,i The previous content will not be executed , Whether to execute the following contents to see if there is break sentence .

If switch Replace the sentence inside with

    default:printf("%d",i+1);
    case 1:printf("%d",i);break;
    case 2:printf("%d",i);break;

The output is 10 1 2 43. If you will case 1 hinder break Replace with continue, The output is still 101243.

summary ：continue Statement will terminate switch loop , bring for Inside i Become the next （ That is to end this cycle , Start the next cycle ）. So in this case continue And break about switch It's the same thing , And as long as case perhaps default Not in use break It will be executed until the last sentence .

Attach the original words of the book （ Madman c The fifth chapter ）：break Statements can also be used in loop statements , The function is to end break The innermost loop statement in which the statement is located ;continue Statement acts on a loop statement , The function is to turn into a circular statement （） Continue to execute loop statements within .
