What is the advantage of a random access file?

Short Question

9934

Answer:

If the amount of data stored in a file is fairly large, the use of random access will allow you to search through it quicker. If it had been a sequential access file, you would have to go through one record at a time until you reach the target data. A random access file lets you jump directly to the target address where data is located.

478. Describe how arrays can be passed to a user defined function

Answer: One thing to note is that you cannot pass the entire array to a function. Instead, you pass to it a pointer that will point to the array first element in memory. To do this, you indicate the name of the array without the brackets.

Answer: Yes, it is possible to pass an entire structure to a function in a call by method style.

This method helps maintain consistency and uniformity in terms of argument type.

Answer: Use the fseek() function to perform random access input/ouput on a file. After the file was opened by the fopen() function, the fseek would require three parameters to work: a file pointer to the file, the number of bytes to search, and the point of origin in the file.
