Answer)
1) For the creation of binary files, prot parameter is being used for specifying the protection as well as permission of the file where the multiuser operating system like the Unix is to be used and allows for specifying what user is being allowed for looking at the file.
There are many operations which help to read and write the binary files:
ios:in -> Specifies which type of input is made.
ios:binary--> This makes the file to be accessible as binary file.
This is used for reading the file which is binary
To write the binary file ios:out is the command to be used.

Binary files The binary file data.dat contains characters and numbers- it has 16 characters, followed by numbers of type int alternating with numbers of type double -so after the first 16 characters, there will be an int, followed by a double, followed by an int, followed by a double, and so on. Write a program to open the file and until the end of file is reached, read in the values in the appropriate data types (that is, read...

1. write a java program using trees(binary search treee) to read integers from input file( .txt) and add +1 to each number that you read from the input file. then copy result to another (.txt) file. example: if inpu File has numbers like 4787 79434 4326576 65997 4354 the output file must have result of 4788 79435 4326577 65998 4355 Note: there is no commas in between the numbers. dont give images or theory please.

Creating Graphs First, write Java code in GraphTest.java to read a data file (graph.in) and create a graph using the input data. The input file must have the following format: 6 049 0 27 2 3 1 25 2 1 5 6 352 4 5 1 Here, the number on the first line represents the number of vertices in the graph. The letter on the second line indicates whether this is a directed graph ('D') or an undirected graph ('U')....

Please Only use C language In this assignment, you have to read a text file (in.txt) that contains a set of words. The first line of the file contains 3 numbers (N, S, D). These numbers represent the sequence of input words in your file. N: represents the number of words to read to build a binary search tree. You have to write a recursive insert code to create and insert these words into the binary search tree. After inserting...

C++ Implement Random Access Binary Files. Do Not use Arrays instead write the data directly to Random Access Binary File. New program should be modified to display a menu for the user to do the following: 1. Replace Employee and Department classes with Employee and Department Structures. 2. Inside each structure, replace all string variables with array of characters. 3. Make Employee and Department editable. That means, the user should be able to edit a given Employee and Department. 4....
