If I wanted an int connected to a float connected to a string connected to a POD, would all I have to do is :
Code:
template<class T, class X>
struct node {
T data;
node<X> *next;
};
Or would I be forced into using polymorphism?
How can I make fgets stop reading when it reaches a new line? Right now it will read the new line and continue until the buffer is full. I was thinking something like this.
Code:
while(fp!='
'){
fgets(password, 256, fp);
}
OK I'm making a simple program to make a shopping list. I would like the program at start up to load the previous shopping list that was saved as a text file. The format is one line per entry which consists of the category or Isle, and the item description. Here's an example:
3 Dog Food
Produce Sweet Onions
I reading the first word, and then I want to read the rest of the line which may have more than one word... the problem is my code hangs... or goes into the old infinite loop. It doesn't see the end of file.
Here is my code:
void
addItemsFromFile(vector<item> &shoppingListVector) {
string word;
char buf[30];
if (fileExists("shoppinglist.txt"))

I want the numbers to be put into the array until it hits a new line. Maximum number of numbers is 1000. What can I replace that while loop with to stop it from reading further into the input file?
Code:
while (input != '
'){
for(i=0; i<1000; i++)
fscanf(ifp, "%lf", &auctions_prices[i]);
I want to make an object, which moves from x1,y1 to x2,y2 in a straight line, also make a sinus over the line (so the x,0 is the line itself, and cux,cury is the object. So the object will move as a sinus over the line. How do I do this in c++?

class Transaction{
private:
char type;
double amount;
double balance;
string description;
[Code] .....
This part is what I am having trouble with as this section is not printing anything.
for (int i = 0; i < transactions.size(); i++){
cout << transactions[i].gettype() << " ";
cout << transactions[i].getamount() << " ";
cout << transactions[i].getbalance() << " ";
cout << transactions[i].getdescription() << " ";
}
}
Other than the theoretical difference between cout and cerr where the former puts values to the monitor and the latter puts values related to errors to the monitor, is there any real difference here? Why not use cout when you want to send anything to monitor? Why use cerr at all?

//fp_screen.h
class fp_screen{
public:
double fps;
double xx3;
[Code] .....
fps:1.16922e+006 // this will happen 80%
fps:900 // this is how it should be
if i do cout << "fps:" << (int)screen.fps << endl;
Somethings number is right like 800 or else
put sometimes its 5423423... something.

Am having a problem with the following program not displaying the cout after the while loop, it doesn't ask if I want to enter another employee but just prompts for the employee payrate again.

using namespace std;
int main()
// Parameters: None
// Returns: Zero
// Calls: None

Iam working with arrays and i cant get to the write solution to cout the characters.
the Question is : Write a program that inputs a character string from the user as an input (using cin.get())and store it in myStr[ ] array.Assume that the length of the input string is less than 100 characters and the string may contain lower case, upper case, and/or symbols.The program should then print the number of lower case, upper case, digits, and symbols along with the characters themselves.
my code :
#include <iostream>
#include <string>
#include<iomanip>
using namespace std;
int main() {
int ctr1=0, ctr2=0, i=0, ctr3=0;
[Code] ...
What i have now, how can i cout the uppercase characters and the lower case characters and the symbol characters !
Finally got to functions. Made a simple one that adds two numbers:
Code: int add(int a, int b){
cout<<"a+b=";
return a+b;
}
It refuses to give an output unless I use cout.
If I just call the function like so: "add(12, 24);", shouldn't it print out a+b=36? It only prints out "a+b=", unless I use "cout<<" ahead of the call.
My simple question is why does it need cout ahead of the call? Shouldn't "return" do its job and print out the number?
i ran the following code in the latest version of code::blocks and it tells me that the objects cout and cin are not declared in this scope. what is the problem?
I used to use Turbo C++ 3.0 and i had no problem whatsoever with that compiler. But now i am trying to move to code::blocks but it is proving very very hard as all the standards have been changed.
I am a school student and thus, we had been told to practice on Turbo C++ 3.0 and now i am unable to unlearn it. Also, if i use printf in place of cout there is no error but i want to use cout as it is what i am comfortable working with.
#include<fstream>
#include<conio.h>
int main() {
using namespace std;
char name[20];
[Code] ....
Is there some document to which i can refer so as to get the latest C++ standards which is C++0x i believe?
I m working calculating stuff in files, input and output data, etc..., the question is the following: I output double numbers with:
myFIle << fixed << setprecision(10) << double;
The problem i got is that when a numer is like 193123.2 it prints like 193123.200000..., so finally, ¿how can i print it with any additional 0 that i need?.
I'm trying to build a new project and i installed some new libraries in it but when i try to compile any code it doesn't give me any value just press any key to continue, i didn't make any files but one and even if i tried to do this simple task it doesn't cout any result:
#include<iostream>
using namespace std;
int main() {
cout <<("ha");
system("pause");
return 0;
}
I am beginner in C++ programming. I having a problem to show the output of all the element i store at a array called total_price. the output become unreadable.
#include <iostream>
using namespace std;
int main () {
float price[1]={0};
int qty;
[Code] ....
So I want to go from having 0 or 1 to having words like false or true. I did it with an if statement earlier today, but I had to get rid of the whole bool thing. I made the variable just a float. But he requires we use bool. Here is my code:
Car y;
cout << "Initial value for the Car: " << endl;
cout << "Age= " << y.getAge() << " years old. The Price= $" << y.getPrice() << endl;
y.setAge(8);
y.setPrice(12000);
y.setRaceCarStatus(true);
cout << "Modified value for the Car: " << endl;
[Code]...
I commented (//) the if statement that I had earlier. If I set RacecarStatus to True, is cout's 1. The starred (*) line right above the comments is the line that I was required to add. I want to cout the actual word true. The one I had this morning won't work anymore.
I have more programming before this, but everything else works fine. My else loop has an infinite output. i also want it to output an error message if the value is not an integer and return to the input
cout << "Select number corresponding material for fencing:" << endl;
cout << "wood = 1" << endl;
cout << "stone = 2" << endl;
cout << "aluminium = 3" << endl;
cin >> material;
if (material == 2){
cost = 100 * perimeter;

I'm making a very first program. It's very little more then a simplistic calculator, but i'm having a problem with the cout function. It won't display any text what could the reasons be?

int main () {
do {
int(a);

Oh and i'm aware it's still riddled with numerous problems, I just have been working on the cout thing first.
I'm building a Console class(i realy need it). and i don't understand how can i build the Write() procedure. Heres the structure:
write(varname1[,varnamex])
how can i convert it to cout?
Getting error: no operator "<<" matches these operands at line 36.

Im trying to run my program and it works fine until the very end where I want it to read "<name> is a <gender> citizen of <nation>." with the corresponding variables. Here is my work for the time being. Also is there a way to make it where if someone puts a M or m for gender, it will spit out Male instead of just m or M.
#include <iostream>
using namespace std;
int main()
{
char gender;

So in a nutshell I have to write a program that grabs a random line from a file and exchange the numbers for words from other files to create a poem. The problem I have is that when I go to output the parts of the ntca it gets all jumbled and writes over each other. (See output below)
I saw something about a memory leak, but I couldn't see how that could be happening in this program. It's a basic intro level program for a class and I'm just a little stuck.
Code:
void create_poem(const int poem_lines) // called from main function {
//Peform each for each line
for(int x = 1; x <= poem_lines; x++) {
char begin_line[1000];
[Code] ....
Everything works perfectly except for the output which looks like this :
Code:
A 2 2 1 and 1 3 1 // <-- this is the line before translation
junkcarrnet
As stated, I know everything else works through debugging purposes. Just the overwriting is my only problem.
