Thread: Books with Real world exersises

The problem is that most real world exercises would be too big and too complex for people just learning. Im sure theres some calculator examples and stuff, if thats what you mean.

Code:

#include <stdio.h>

int main()
{
   int result, num1, num2;

   while(result!=0)
   {
      printf("\n\nenter num 1 then num2, enter 0 0 to exit");
      scanf("%d %d", &num1, &num2);
      result=num1+num2;
      printf("\n\n%d", result);
   }
   return 0;
}

there you go, simple calculator

There are a few big differences between real world code and kiddie code for students:

1) Error checking. Real code has a ton of it, at least 2/3 of a program should be error checking.

2) Error handling. The last thing you should do is terminate the program, real code will try to recover a few times.

3) Input validation. Users are fools and real world code should try to be fool proof.

4) Bubble sort. You never see it.
