Which type casting is accepted by C?

typecasting is more use in c language programming. Here, It is best practice to convert lower data type to higher data type to avoid data loss. Data will be truncated when the higher data type is converted to lower. For example, if a float is converted to int, data which is present after the decimal point will be lost.
