NettetType Casting is also known as Type Conversion. For example, suppose the given data is an integer type, and we want to convert it into float type. 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 2nd example: float num = 5.25; int x;
