These are the 5 memory segments and what is stored in each.
What are

This step combines multiple object files into an executable.
What is linking?

This is the output of the following code:
What is segmentation fault?
500
This is a problem with the following code and how to fix it.
What is memory must be allocated for each word, not just the pointers to the words; strcpy is copying to random memory addresses?
500
Two parts, each worth 500 points:
1. This is the output of the following program.
2. This is the memory segment where each variable is stored (hint: there are 5 variables).
1. What is "error :( -60"?
2. What are count: BSS; error_message: data; count: stack; num: stack; arr: stack?
