WebApr 11, 2024 · Implicit type conversion in C++ is the process of automatically converting one data type to another data type. It is also known as type coercion. The compiler will perform implicit type conversion when the data type of an expression does not match the data type of the variables involved in the expression. WebFollowing is the simple syntax to define a new type using typedef − typedef type newname; For example, the following tells the compiler that feet is another name for int − typedef int feet; Now, the following declaration is perfectly legal and creates an integer variable called distance − feet distance; Enumerated Types
