Program 2

Program 3

These two programs are based upon each other. Mostly need help with program 3. Written in C

For this exercise you must write a program which generates a set of random integer pairs and stores them in a binary file using system calls. The program should meet the following criteria: 1. The program should be named createFile 2. The program should be able to be called in one of two ways: 1. createFile 2. createFile The command line arguments represent the following: - - name of the binary file, if the value isn't specified default it to image.dat - -total number of integer pairs to generate, if this value isn't specified default it to 60 The createFile program will follow a simple process: 1. loop while all the integer pairs haven't been written to the file 1. generate a random number between 97 and 122; these are the ASCII values for 'a' 'z'. 2. generate a random number between 5 and 20 3. store the values in a struct containing a char and a short int 4. output the struct to the file using write. This program will use the file created in Program 2. The program should read the integer pairs from the "image.dat" file and display the data read in two forms. The first form is the character - integer pairing and should be displayed as (character, integer). The other form can be thought of as the pairings decoded form; the character - integer pairing ('b',6) would be decoded as 'bbbbbb
