Question

(Create a binary data file) Write a program to create a file named CreateBinaryFile.dat if it does not exist. Append new data to it if it already exists. Write 50 integers created randomly into the file using binary I/O.

Answer 1

Using C Programming language:-

1st image is the code for creating a Binaryfile.dat

1) .dat file can be opened by notepad.

2) In the program I generate the 50 numbers below 100 only.

3) You can generate any 50 values by changing the 100 to your desired value

ex:- 100000000 ( the program generates 50 values from your value).

4) You can change this in the line n=rand()%100+1.

5) 2nd image is the output

6) we cannot see the output in the compiler.

7) The program directly writes the output (50 random numbers) in the BinaryFile.dat

2nd image is the output

we cannot see the output in the compiler.

The program directly writes the output (50 random numbers) in the BinaryFile.dat
