Type inference with auto

soccer: DJ[ˋsɔkə]

Type inference with auto is a feature in C++ that allows the compiler to deduce the type of a variable based on its initializer. Instead of explicitly specifying the type, you can use auto, and the compiler will determine the appropriate type automatically.

In C++ type inference, when using auto, a floating-point literal like 1.0 is inferred as a double by default. This is because, according to the C++ standard, floating-point literals without a suffix (f for float, l for long double) are treated as double.

Float is a single-precision floating-point type, typically storing 7 decimal digits of precision, whereas double is a double-precision type, storing 15-16 decimal digits

The typeid operator in C++ is used to determine the type of an object at runtime. It returns a reference to a type_info object that represents the type of the given expression or type identifier.

The bool type in programming represents a Boolean value, which can be either true or false. It is commonly used for logical operations and conditional statements.

In C++, string literals are enclosed in double quotes (" "). This distinguishes them from character literals, which are enclosed in single quotes (' ').

PKc stands for pointer to const char.

 In C++, PKc is the mangled name for const char*. The breakdown is:

- P → Pointer

- K → Const qualifier

- c → Char type
