For this assignment, you will write 2 programs in C, and compile and run them from the command line.
Program 1: simple statistics
Write a C program that prompts the user to enter an integer indicating the count of numeric values to follow. After this, read in count double values and load them into an array. Use printf and scanf for IO.
Calculate and print out the min, max, average, median and mode of the numeric values entered.
Make sure to properly free array memory before the program exits.
I suggest coding your own insertion sort to sort the input as it is entered. This will facilitate the calculation of median and mode.
Program 2: random text square
Write a C program that takes two numeric command line arguments: width and height. This program should print out a block of random text letters with the prescribed dimensions: width characters per line, height lines.
Command line parameters can be accessed via in the char* array that is the formal parameter for the main subroutine. (Remember, char* is the datatype we use for strings, so this parameter eﬀectively stores an array of strings – you will need to convert these to int).
This program should allocates a char array of the appropriate size – ((width+1)*height+1) to store all random characters, newlines and the NULL at the end. Then it should fill it randomly, as appropriate, print out the buﬀer and free up the allocated array. Make sure to NULL-terminate the string.
Note, the char literal ’\n’ can be used to include newlines within a NULL-terminated string. You must load an array for full credit. Don’t just print out random text.
Make sure to compile using the -Wall flag to alert you to all compiler warnings.
You’ll need to look up documentation for diﬀerent functions and subroutines. Here are some that you may find helpful:
– atoi – converts a NULL-terminated string to an int
– rand / srand – generate pseudorandom numbers / seed the random number generator ( seeding is pretty interesting! )
Ask me for help! Start early enough to have time to get the needed help.
Make sure you are doing your own work, and not using code from the internet. Turning in code that you did not write yourself is a violation of the honor code and you will be referred to the UTC Honor Court.
Turn it in.
Put all C files in a zip file and submit to blackboard. Code must compile to be eligible for points.
Include screenshots illustrating the programs in action.
