Which of the following best describes the primary purpose of 'storage classes' in C programming?
Which of the following best describes the primary purpose of 'storage classes' in C programming?
- To define new data types for variables.
- To perform mathematical calculations.
- To manage input and output operations.
- To determine the scope, visibility, and lifetime of variables and functions. (correct)
Given that ptr is a pointer in C, which operation would correctly deallocate the memory block ptr points to, preventing memory leaks?
Given that ptr is a pointer in C, which operation would correctly deallocate the memory block ptr points to, preventing memory leaks?
- `free(ptr);` (correct)
- `ptr = NULL;`
- `realloc(ptr, 0);`
- `calloc(ptr, 0);`
What is the primary difference between passing an argument 'by value' versus 'by reference' to a function in C?
What is the primary difference between passing an argument 'by value' versus 'by reference' to a function in C?
- There is no difference; both methods achieve the same result in C.
- Passing by value is used for simple data types, while passing by reference is used for complex data structures.
- Passing by value creates a copy of the variable, while passing by reference allows the function to directly modify the original variable. (correct)
- Passing by value allows modification of the original variable, while passing by reference only allows reading the variable's value.
