Code examples

The following code example fails the check and will give a warning:

void example() {
  for ( int i = 0; i < 10; ++i ) 
  {
    i += 1; // Non-compliant
  }  
}

The following code example passes the check and will not give a warning about this issue:

void example() {
  for ( int i = 0; i < 10; i += 2 ) 
  {
     ; // Compliant
  }  
}
