So, we need to manually cast int data to the float type, and this type of casting is called the Type Casting in C++. int num = 5; float x; x = float(num); x = 5.0. WitrynaC++ Type Conversion. In this tutorial, we will learn about the basics of C++ type conversion with the help of examples. C++ allows us to convert data of one type to that of another. This is known as type conversion.
