When compiling a program with the Microsoft C/C++ compiler, the following error may be generated if an integer constant is recognized syntactically as being in an illegal location:
Microsoft C/C++ 7.0 and Visual C++ may generate the following:
error C2059: syntax error: 'int constant'
C2143: syntax error: missing ';' before 'constant'
Depending on the code, this error may result from a failure to include a line continuation character in a multi-line #define or macro definition statement, or from placing an integer constant on a line by itself.
C2143: syntax error: missing ';' before 'int constant'
The sample code below demonstrates how this particular error might be generated. The #define statement spans two lines, but the line continuation character (a backslash) was inadvertently omitted from the end of the first line. This causes the compiler to "see" the integer constants as being on a line by themselves without any contextual meaning, and thus the C2059 error is generated.
