I'm working on porting some old K&R code to ANSI C, so I'm writing missing function prototype declarations. A lot of the function definitions have parameters with the register storage class, but I'm not sure if the register storage class specifier can be omitted in the function prototype?
I am a big fan of CodeSignal, but I found a strange piece of C++ grammar (the first line):Is defining string r, in the function declaration valid in modern C++?
This question already has an answer here:As per my knowledge, final variables must/can be initialized only once otherwise compiler is supposed to throw an error.
I'm reading 'C++ All-in-One for Dummies' by J. P. Mueller and J. Cogswell and stumbled onto this:This code starts out by initializing all the goodies involved — two integers and a pointer to an integer.
This question already has an answer here:In the C language, if we write this:The scope of variable i is inside the for loop body. It is OK.
This question already has an answer here:In C language, If we write like this :The scope of variable i is inside the for loop body. It is Ok.
Here is my code:When I try to compile and run this program, I get these warnings:How can I initialize these loop counters declared with auto such that the code is safe and there are no warnings?
GCC and Clang disagree on whether template<typename>; is a valid statement in C++ at global scope.
