Hi all, 0.I read that ANSI C rules for variable declaration says that one must declare the variables at the beginning of any scope block. C99 onwards we are allowed to declare variables as & how required. 1.NOW, my doubt is what happens in the actual "practical/real-world" codes that are written in industry. *Do everyone *strictly* follow the ANSI C rules & declare the variables at the beginning of the scope ? * 2.Also , why are we still following that old rule ? *Is it so that old codes of 70s can be used with new codes ?* 3.There must be some standard that all of us need to follow , so what are they ? This point is very crucial for free & open-source projects , where people all around world write codes. *Can any one redirect me to some links/tutorials for the same ?* Regards, free4freedom
