The difference between the new and open commands on the file menu are quite simple. The new command creates a brand new file, while the open command opens a file that already exists or has been created.
Answer and Explanation:
Given that total number of records in a file = 100000
Each record consists of= 240 bytes
Given that B= 2400 bytes.
Then total blocks in file = 100000 records * 240 / 2400
= 10000 blocks.
Time that will take for exhaustive read
= s + r + b.btt
= 16 + 8.3 + (10000) * 0.8
= 8024.3 msec
Now as per given X be the number of records that are searched randomly and it takes more than exhaustive read time.
Hence, X (s + r + btt) > 8024.3
X (16+8.3+0.8) > 8024.3
X > 8024.3/25.1
So that, X > 319.69
Hence, atleast 320 random reads should be made to search the file

The syntax is truly dependent on the programming language, as different languages have different API's.
But, the most standard form of accessing an array length is via a method or property by dot notation.
For example -
for(int i = 0; i <= m_Array.Length; i++) {...}
This code is from C#, using the Length property.
