Why are memory errors hard to debug?
The first thing to understand about memory errors is why they're different from other bugs. I claim the main reason they are harder to debug is that they are fragile. By fragile, I mean the bug will often only show up under certain conditions, and that attempts to isolate the bug by changing the program or its input often mask its effects. Since the programmer is then forced to find the needle in the haystack, and cannot use techniques to cut down on the size of the haystack, locating the cause of the problem is very difficult.
Consequently, the first priority when tracking down suspected memory errors is to make the bug more robust. There is a bug in your code, but you need to do something so that the bug's effects cannot be masked by other actions of the program.

I'm having trouble with coming up with the correct code. Do I need to put a loop? Please let me know if I'm on the right track and what areas I need to correct. I still don't have a good grasp on this programming stuff. Thanks =) The assignment was to write a program using string functions that accepts a coded value of an item and displays its equivalent tag price. The base of the keys: 0 1 2 3 4 5 6 7 8 9 X C O M P U T E R S Sample I/O Dialogue: Enter coded value: TR.XX Tag Price : 68.00
Given that two int variables, total and amount , have been declared, write a sequence of statements that: initializes total to 0 reads three values into amount , one at a time. After each value is read in to amount , it is added to the value in total (that is, total is incremented by the value in amount ). Instructor's notes: If you use a loop, it must be a for loop. And if you use a loop control variable for counting, you must declare it.
Write a c-programe that input one number of four digits and find digits sum?
Assume that the int variables i and j have been declared, and that n has been declared and initialized. Write code that causes a "triangle" of asterisks of size n to be output to the screen. Specifically, n lines should be printed out, the first consisting of a single asterisk, the second consisting of two asterisks, the third consistings of three, etc. The last line should consist of n asterisks. Thus, for example, if n has value 3, the output of your code should be * ** *** You should not output any space characters. Hint: Use a for loop nested inside another for loop.
