2. | Point out the error in the program (in Turbo-C). |
| A. | Error: unknown max in declaration/Constant expression required |
| B. | Error: invalid array string |
| C. | No error. It prints A A |
| D. | None of above |
|
| Answer: Option A |
|
|
| Explanation: |
|
Step 1: A macro named MAX is defined with value 128
Step 2: const int max=128; The constant variable max is declared as an integer data type and it is initialized with value 128.
Step 3: char array[max]; This statement reports an error "constant expression required". Because, we cannot use variable to define the size of array.
To avoid this error, we have to declare the size of an array as static. Eg. char array[10]; or use macro char array[MAX];
Note: The above program will print A A as output in Unix platform. |
