Which of the following best describes the purpose of 'strong typing' in programming languages?
Which of the following best describes the purpose of 'strong typing' in programming languages?
- To explicitly declare the type of each variable, thus reducing type-related errors. (correct)
- To allow variables to change their data type during program execution, enhancing flexibility.
- To enable the use of weakly-typed variables for improved performance.
- To automatically infer the type of a variable based on its usage, simplifying code.
