C Type Conversion

C supports type conversion, which is the process of converting a value from one data type to another. There are two types of type conversions in C: implicit type conversion and explicit type conversion.

  1. Implicit Type Conversion - This occurs automatically when a value of one data type is assigned to a variable of another data type. For example, when an int is assigned to a float variable, the int value is automatically converted to a float value:
1int a = 10; 2float b; 3b = a; // implicit type conversion
  1. Explicit Type Conversion - This is performed using type casting, which involves specifying the data type that you want the value to be converted to. For example, you can convert a float to an int using type casting:
1float c = 10.5; 2int d; 3d = (int) c; // explicit type conversion using type casting

It is important to note that when converting from a larger data type to a smaller data type, some precision may be lost. For example, when converting a float to an int, the fractional part of the value is lost.

Type conversion can be useful in situations where you need to convert a value from one data type to another to perform a specific operation or when you need to match the data type of an argument in a function call. However, it is also important to use type conversion carefully, as it can also lead to unintended consequences if not used correctly.
