Compiler Warning (level 1) C4138

  • Artikkeli

'*/' found outside of comment

The closing-comment delimiter is not preceded by an opening-comment delimiter. The compiler assumes a space between the asterisk (*) and the forward slash (/).

Example

// C4138a.cpp
// compile with: /W1
int */*comment*/ptr;   // C4138 Ambiguous first delimiter causes warning
int main()
{
}

This warning can be caused by trying to nest comments.

This warning may be resolved if you comment out sections of code that contain comments, enclose the code in an #if/#endif block, and set the controlling expression to zero:

// C4138b.cpp
// compile with: /W1
#if 0
int my_variable;   /* Declaration currently not needed */
#endif
int main()
{
}
