# V626. It's possible that ',' should be replaced by ';'. Consider checking for typos.

The analyzer has detected a potential error: comma ',' is written by accident instead of semicolon ';'. This misprint can lead to an incorrect logic of program execution.

Consider an example:

    int a;
    int b;
    ...
    if (a == 2)
      a++,
    b = a;

This code will result in executing the "b = a;" expression only when the 'if' operator's condition holds. This is most likely a misprint and ',' should be replaced with ';'. This is the correct code:

    if (a == 2)
      a++;
    b = a;

The analyzer won't generate the message if formatting of a code fragment demonstrates deliberate use of the ',' operator. Here is a code sample:

    if (a == 2)
      a++,
      b = a;

    if (a == 2)
      a++, b = a;

This diagnostic is classified as:

CWE-483
