QA·C Help - 0771

	0771	More than one 'break' statement has been used to terminate this iteration statement.

Control flow

More than one break statement has been used to terminate an iteration statement, i.e. a while, do ... while or for statement. If multiple break statements are used within the same iteration statement, the code can become dangerously unstructured.

For example:


/*PRQA S 2017,3408,3447 ++*/


extern int x;
extern int y;
extern int z;

extern void foo(int n)
{
    while (n > 0)
    {
        --n;
        if (n == x)
        {
            break;                      /* Message 0769 */
        }
        if (n == y)
        {
            break;                      /* Message 0771 */
        }
        if (n == z)
        {
            break;                      /* Message 0771 */
        }
    }
}
