Learn cpp - Char is defined by C++ to always be 1 byte in size. By default, a char may be signed or unsigned (though it’s usually signed). If you’re using chars to hold ASCII characters, you don’t need to specify a sign (since both signed and unsigned chars can hold values between 0 and 127).

 
12.7 — Introduction to pointers. Pointers are one of C++’s historical boogeymen, and a place where many aspiring C++ learners have gotten stuck. However, as you’ll see shortly, pointers are nothing to be scared of. In fact, pointers behave a lot like lvalue references.. Alain dupetit

With Visual Studio, you will need to reselect your language standard every time you create a new project. To select a language standard, open your project, then go to Project menu > (Your application’s Name) Properties, then open Configuration Properties > C/C++ > Language.Actually handling exceptions is the job of the catch block (s). The catch keyword is used to define a block of code (called a catch block) that handles exceptions for a single data type. Here’s an example of a catch block that will catch integer exceptions: catch (int x) { // Handle an exception of type int here.std::move. In C++11, std::move is a standard library function that casts (using static_cast) its argument into an r-value reference, so that move semantics can be invoked. Thus, we can use std::move to cast an l-value into a type that will prefer being moved over being copied. std::move is defined in the utility header.The C programming language was first released in 1972, making it one of the oldest still used today.

While this is a great start down the road to generalized programming, it doesn’t solve all of our problems. In the language standard, a “user-defined type” is any class type or enumerated type that is defined by you, the standard library, or the implementation (e.g. types defined by the compiler to support language extensions).
