C break statement
C languagebreak statement has the following two ways:
- When abreak statement occurs within a loop, the loop will be immediately terminated and the program flow will continue to implement immediately the next statement cycle.
- It can be used to terminatethe switch statement in a case.
If you are using a nested loop (ie a loop nested inside another loop), break statement to stop the execution of the innermost loop, and then start the next line of code after the block.

Examples
#include <stdio.h>
int main ()
{
/* 局部变量定义 */
int a = 10;
/* while 循环执行 */
while( a < 20 )
{
printf("a 的值： %d\n", a);
a++;
if( a > 15)
{
/* 使用 break 语句终止循环 */
break;
}
}
return 0;
}
When the above code is compiled and executed, it produces the following results:
a 的值： 10 a 的值： 11 a 的值： 12 a 的值： 13 a 的值： 14 a 的值： 15
