#pragma warn Directive: This directive is used to hide the warning messages which are displayed during compilation. This may be useful for us when we have a large program and we want to solve all the errors before looking on warnings then by using it we can focus on errors by hiding all...
The compiler also supports the Microsoft-specific__pragmakeyword, which has the same functionality as the#pragmadirective. The difference is, the__pragmakeyword is usable inline in a macro definition. The#pragmadirective isn't usable in a macro definition, because the compiler interprets the number...
