Which of the following is a strong indication that C is a strongly typed language?
Correct answer: D. Type conversions require explicit casting
- A. Every variable must be declared before it is used
- B. C code needs to be compiled before execution
- C. C has a rich set of data types
- D. Type conversions require explicit casting
Explanation
• Strongly typed languages enforce strict type checking. This means that the data type of a variable is associated with it at the time of declaration, and any operations or assignments involving the variable must adhere to its data type.In C programming:• Type conversions are operations that change the data type of a value.• Explicit casting is the process of manually instructing the compiler to convert a value from one data type to another. This is done using casting operators like (int), (float), etc.The requirement for explicit casting in C is a strong indicator of its strict type checking nature. The compiler enforces type safety by requiring the programmer to explicitly declare any data type conversions, helping to prevent potential errors caused by unintended type mismatches
