Question
Match the LIST-I with LIST-II Choose the correct answer from the options given below:LIST-I (file mode parameters) LIST-II (Meaning) A. ios::ate I. Go to end of file on opening B. ios::in II. Open fails if the file already exists. C. ios::nocreate III. Open file for reading only D. ios::noreplace IV. Open fails if the file does not exist.
The correct answer is
A-I, B-III, C-IV, D-II
Matching C++ File Mode Parameters
Understanding the File Stream Parameters
This question requires matching C++ file stream opening mode parameters (LIST-I) with their corresponding meanings (LIST-II). These parameters control how a file is opened and accessed.
Parameter Meanings
- ios::ate: Sets the initial position of the file pointer to the end of the file upon opening.
- ios::in: Specifies that the file is to be opened for reading (input operations).
- ios::nocreate: If the file specified does not exist, the open operation fails.
- ios::noreplace: If the file specified already exists, the open operation fails.
Correct Matching
Based on the definitions, the correct pairings are:
- A. $ios::ate$ matches with I. Go to end of file on opening.
- B. $ios::in$ matches with III. Open file for reading only.
- C. $ios::nocreate$ matches with IV. Open fails if the file does not exist.
- D. $ios::noreplace$ matches with II. Open fails if the file already exists.
Solution Summary Table
| LIST-I | LIST-II |
| A. ios::ate | I. Go to end of file on opening |
| B. ios::in | III. Open file for reading only |
| C. ios::nocreate | IV. Open fails if the file does not exist |
| D. ios::noreplace | II. Open fails if the file already exists |
Therefore, the correct combination is A-I, B-III, C-IV, D-II.
