Lab04 - Strings and (de)allocation

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

Remember you can use #include <string.h> for helper functions

Let's declare an array of characters, and then ask the user for their first name

Print the name, its length, and say if it's the same as your own name

You can use the function strcmp to compare the strings, will return zero if the same

Modify your program to use dynamic memory for the name

Ask the user for other names

Use realloc to make the original name string bigger

Use memcpy to append the additional name to the original name/string

Write a program which allows the user to enter “infinite” amounts of text, and will keep appending it to a string (char array).

When they press enter, it will output the current string.

If they enter a certain character, it will close.

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.

Update the previous code to read a whole word from the input.

Implement your own version of the strcmp() function from the string.h library.

Hard-code your name into your program, and ask the user to input words.

If it matches your name, print a message!

Can you make it case insensitive?
