 | use a linked list of structures. Read a value from the file, search the list to see if its already in the list. If found just increment the count. Otherwise if not found then add a new node and initialize the count to 1. Note: for [b]value[/b] in the below …  |
| | What? there is nothing to correct because the function [b]even[/b] already returns true or false, unless you just want to rewrite it like this: [code] bool even(int x1) { return (x1%2 == 0) ? true : false; } [/code] |
| | line 12: should be this: [icode]while(p)[/icode] Your program gets segment violation when strtok() returns NULL. >>I realize its probably overkill for my purpose so if anyone could point me to a simpler solution that would be appreciated too.

| | how about a linked list ? or something like this: [code] void foo(int x) { int n = 0; cout << "Enter a number " << x << ":\n"; cin >> n; if(x < maxNum) // maxNum declared elsewhere foo(x+1); cout << "n = " << n << "\n"); } …  |

| | Re: C++ arrays The first line initializes the values of the array. The second line is a syntax error. It should be [icode]int* ptr = &array[0];[/icode] The last line sets the value of te first array element to -1. |

| | If you want [b]findMax() to change the value of ptr in main() then you have to pass the parameter by reference and not by value. [code] void findMax(int arr[], int n, int** pToMax) { ... *pToMax = &arr[0]; } int main() { ... findMax(nums, 4, &ptr); } [/code] Or since … |
 | Your code formatting is absolutely horrible! Completly unreadable. And that is probably why you don't understand the error. Reformat it, indent it properly, and you will probably see the problem. And don't be afraid to put { and } on their own separatelins, unlike the horrible code in line 122. |
| | This is one way to do it. [code] int main () { float f = 123.457678F; int a = (int)f; float b = f - (int)f; if(b > 0.5F) a++; cout << a; return 0; } [/code]  |

| | >>that means tells the operating system a program finish? No. There is other code that you did not write that does that. main() returns not to the os but to the start-up code that called main(). What that startup code does is not specified by standards and is therefore different … |
| | Line 17 should be moved to the first line of main() because srand() should be called only once throughout the lifetime of the program. lines 17-21: If you want to keep asking the questions then why didn't you use a [b]while[/b] loop here ? The [b]if[/b] will execute it only … |

| | You are confusing a vector of ints with a vector of student_record classes. [b]ex[/b] is an array (or vector) of integers, not student_record classes. And that's why your compiler is complaining about lines 32 and 33. [edit]^^^^ what Duoas said more detailed than what I said[/edit] |

I realize you might not be using the same compiler but you should have gotten similar errors. error C3861: 'counter': identifier not found error C3861: 'incorrect': identifier not found error C3861: 'correct': identifier not found  |
| | can't help you, sorry. You are using too ancient a compiler, non-standard header files and obsolete stream header files. Delete dos.h and conio.h, then replace <iostream.h> with <iostream> and replace <fstream.h> with <fstream> then maybe, just maybe people might be able to help. |
| | I don't see anything that would cause the problem you report, but I do see problems with that [b]square()[/b] function. In main() if you first select 'S', the value of the three variables are all 0. I don't know what [b]minMax[/b] does, but assume it finds the minimum and maximum … |

| | The second parameter to OpenData() should be char* not simply charf [icode]void OpenData(int ** arrayPtr, [color=red]const[/color] char[color=red]*[/color] file, int *arraySizePtr )[/icode] Didn't your compiler give you a bunch of errors because of that? There are several other syntax erorrs too, and in some cases you need to add typecasts. |

| | The only way you could possibly access it is if the variable is global and non-static. In that case you could declare it with the [b]extern[/b] keyword in your program. If your program links then you should be ok. If it doesn't link, then tough luck, you will not be … |

| | Line 53: T is uninitialized so its value is any old random value, including 0. You need to initialize it to some known value on line 51. Using a while statement to read integers here is not a good idea because the >> operator does not stop at end-of-line. Better … |

| | I think I would use a [b]vector[/b] of structures. You need two structures [code] struct numbers { int saleNumber; float amount; }; struct person { int ID; string lastName; string firstName; vector<numbers> numberList; }; [/code] Now just make a [b]vector[/b] of the above person structor, e.g. [icode]vector<person> personList[/icode] |
The End.
