Lab04 - Arrays

A command-line argument specifies the number of integers to read (N)

Read N integers from standard input using scanf() to a variable-length array of size N

Print the array in the order entered

Sort the array in descending order using qsort()

Print the sorted array

Write a program which allows the user to enter an “infinite” number of characters and will keep appending them to an array.

When they press P, it will output the current array.

If they enter a character X, it will convert the chars to upper case with toupper(), print them and exit.

Use the getchar() function to get letters from the command line.

You will need to use malloc() and realloc() to control the memory.

Don’t forget to use free() at the end to free the memory.

If you have time, add also sorting the chars alphabetically and lower case before upper case.

use valgrind for memory leak detection

can detect forgotten allocated memory and the exact location of out-of-bound access

can report using uninitialized variables/memory

for better output, compile your program with -g flag

valgrind ./your-program

Learn to understand the function declaration (the name, return type, and parameters)

The definition (code to be executed) might not always be available
