      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++.
