QA·C Help - 0769

	0769	A 'break' statement has been used to terminate an iteration statement.

Control flow

A 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 */
        }
    }
}
