    In how many ways we can initialize an int variable in C++?

  • #51869

    In c++, variables can be initialized in 2 ways, the traditional C++ initialization using “=” operator and second using the constructor notation.

    Traditional C++ initilization

    int i = 10;
    variable i will get initialized to 10.

    Using C++ constructor notation

    int i(10);
    Implicit conversions are performed when a type (say T) is used in a context where a compatible type (Say F) is expected so that the type T will be promoted to type F.

    short a = 2000 + 20;

    In the above example, variable a will get automatically promoted from short to int. This is called implicit conversion/coercion in c++.
