doing VC++

1, when you met strange question , not knowing how it occure, delete the project and restart, because the compiler has problem, they just have problem, get get trapped in it.

 

2，vc6 not fully surpport C99, varieables should be defined at the start position.  For this point, the error give indication: missing ';' before 'type'

 

3, vc6 just suck, when build a c project with console appliaction, choose c file doesn't work at the building stage. add a new C file later for C coding.
