Dev-C ++ 4.9.6.0 Problems

Today I wrote a project about the const experiment.ProgramIn Dev-C ++ 4. 9. 6. 0. It took a long time to debug and discuss it with others in the group ~ I should have tried it in VC. I used to do this before, but I don't know why. I have never tried it ~~ At last, the boy in the group really made me depressed. He started to discuss it with him for a long time. He guessed it by himself. Finally, I tried it in VC. --- I relied on it ~~ Correct!

Int cdemo: get_m_a () const

{

Cdemo: M_a = 10;

Return M_a;

}

This is actually wrong ~~ However, in Dev-C ++ 4.9.6.0, It is correct. In vc6, It is found by the compiler to be wrong. At least it does not comply with the c ++ standard, then I wrote Dev-C ++ 4.9.9.2 and the result was correct!
