usage of string

[vaquar]

I incorporated usage of string variable and after compiling getting around 30 similar warnings. And program runs fine no memory leaks. Wondering why these errors...

All errors are of falls either of C4100, C4663, C4018, C4146, C4244:
*********************************************************

Hi John,

By using #pragma,
the warning increased by 5 (from 30 to 35)

Could you suggest me something else...?

I even tried by changing warninig level in Project Setting(c/c++), but no use.

Thank you

if so, don;t put pragma once John Fill
