The exercise consists on 3 procedures. We get the information from a .txt like these:
01/03/2011 A 02/03/2011 F 03/03/2011 C 04/03/2011 T (...)
Simulating a Videoclub database where the letters stand for the type of movie (A=Action, T=Terror, C=Comedy, ...) and the dates they were rented.
a) How many movies from one specific genre have been rented more than 'n' times? The genre and the value 'n' must be entered by the user.
b) How many movies and which genres belong to a certain date? The date must be entered by the user.
c) Print a list that shows the number of times a movie from each genre has been rented.
So far this is what I've got:
Code: #include <stdio.h> #include <stdlib.h> #include <string.h> #define MAX 100
typedef struct { int dia,mes, any; char genere;
[Code] ....
But right now, my main problem is that I can't even debug because i get an error in line 97 --> while (llista[i][j] != EOF) <-- saying "invalid operands to binary != (have 'lloguer' and 'int').
I've tried to cast (int) before "llista[i][j]" but it says that I'm already supposed to get an integer from that.
output.displayHeader() must execute before the inherited from ostream (cout) executes streaming data, or bad things happen. It's of course not as simple as in the example below, and I need to make sure displayHeader() is never missed.
I'm thinking I need to override the "<<" operator, having my own function call displayHeader(), then call the base (cout) "<<" operator. What's the proper syntax for doing this?
I can't call displayHeader() in the constructor, and I can't call it right after the object is defined. There are exception case scenarios where displayHeader() must not be called, and other things must happen instead.
I'm aware this will result in many redundant bool comparisons versus the way I'm doing it now, and I'm perfectly OK with that.
Code: #include <iostream> using namespace std; class myOutput : public ostream { public: myOutput() : ostream(cout.rdbuf()) {
// Creating and joining string objects #include <iostream> #include <string> using std::cin; using std::cout; using std::endl; using std::string; using std::getline; // List names and ages void listnames(string names[], string ages[], size_t count) {
[Code] ....
I may be wrong, but the problem seems to be in the function "listnames". Specifically, the output statement inside the while loop. I don't understand , how the ++ operator is behaving in this statement. The output produced does not match what's printed in the book. I usually just type all the examples, but with this one I also downloaded the source code from the book's website to make sure the error wasn't due to mistyping.
Okay so inside my ArcherArmor.cpp, I'm trying to figure out why the map initializer list isn't working, but for some reason I keep getting "Error C2593: 'operator =' is ambiguous". Here is my code:
I also have a class which ArcherArmor is derived from, that has a struct called `Armor`, which I left out for simplicity. The main problem is that error! The only thing I can think of is that im initializing the map wrong.
Recently, i successfully overloaded postfix operator to class counter by using Object and Class. Now, i want to overload same postfix operator to Inheritance. I created my code and generated in compiler. But, my compiler signaled me uncommon error(saw first time) and i couldn't generate any idea where my actually mistake is.
Here is my Code which objective is to count the number increasingly or decreasingly as per object created of CountDn class.
Code: #include <iostream> using namespace std; class Counter // base class { protected : // NOTE : Not Private unsigned int count;
[Code] ....

I'm writing a program to read in a Master.txt file and then update it through a Transaction.txt file that contains various transaction types [Adds (A), Deletes (D), and Edits (E1-E4)]. The records in both files are in ascending order based on Item#. Ultimately, the original Master.txt and updated Master file (Master2.txt) will be merged to reflect all valid transactions, and an errorLog.txt file will be created to indicate all invalid transactions. I feel I have all of the code written correctly, but I am still getting errors on my operands and identifiers.
I can't seem to figure out the algorithm to find the right permutation(s) of operands and operators.
We basically have a list of 6 unsigned integers. Using arithmetic operations (addition, subtraction, multiplication, division), find the arithmetic expression that evaluates to a target integer.
I've created a class that works with vectors doing various calculations and what not. I have overloaded operators that I've created outside of the main in separate header and class files. Ive tested them and the overloaded operators work correctly when I paste them into a the main file but when I have them defined in the other class files and I try to access them in the main class I get an error saying invalid operands to a binary expression. I also have other classes with overloaded operators that work just fine in the main class so I'm not sure what I did wrong here?
This is how I have my header set up, the definitions to these are in a separate class file which I don't think I need to include considering I have them tested and working so I don't think that's the problem (correct me if I'm wrong).
#include "Name of vector class" int main(){ vector<float> vR, v1, v2; v1.push_back('some value'); ... v2.push_back('some value'); ... vR = v1 + v2; // Invalid operands here return 0; }
And like I said, I have other classes with overloaded operators set up the same way which work fine being implemented the way I have these, so I'm not sure where the problem is at.
Ive got a football league program that I made to handle 10 teams. Ive got the 10 teams and it displays the league with 0 for played, won, drawn, lost and points but im having trouble actually adding matches to this? How do i add matches and update the team struct?
