Linux ++ code porting to Windows

Linux general technology-Linux programming and kernel information. For details, see below. A few problems have been found recently after porting a program from linux to Windows.

Is the gcc compiler different from vs compiler?

Case1:

When operating on the string class

Last = strtmp2.find _ last_not_of ("\ t ");
If (first = string: npos | last = string: npos)
Return;
String value = strtmp2.substr (first, last-first + 1); // In this sentence, 1 is not required in linux, but 1 is required in Windows.

Case 2:

For (int I = 0; I <10, 1; I ++ );

Result in linux: endless loop

Windows result 10

Conclusion The values of the comma expression are different.

Case 3:

Int nArrayWide = 100;

BYTE testArray [nArrayWide] = {0 };

Linux

Windows compilation Error
