Difference Between Type casting and Type Conversion

Computer ProgrammingProgrammingMiscellaneous

In this post, we will understand the difference between type casting and type conversion.

Type casting

  • A data type is converted to another data type using the casting operator by the developer.

  • It can be applied to any compatible data types and incompatible data types.

  • The casting operator is required to cast a data type to another type.

  • The destination data type could be smaller than the source data type.

  • It happens during the program design.

  • It is also known as narrowing conversion since the destination data type may be smaller than the source data type.

  • It is generally used in coding and competitive programming.

  • It is efficient.

  • It is reliable.

Type conversion

  • A data type is converted into another data type by the compiler.

  • It can be applied to compatible data types only.

  • There is no need to use a casting operator.

  • The destination data type can’t be smaller than source data type.

  • It is done at compile time.

  • It is also known as widening conversion since the destination data type can’t be smaller than the source data type.

  • It is not used frequently in coding and competitive programming since it may result in a wrong answer.

  • It is less efficient.

  • It is less reliable.
