C++ :: Change Number Of Operands An Operator Takes?
Jan 22, 2014It is possible to change the number of operands an operator takes?
I think it is false. Am I right?

C :: Make Program That Takes Number Input From Tuser?
Jul 27, 2013I have to make a program that takes a number input from the user and prints the corresponding fibonacci sequence number. For example, for the input of 3, it should print 2 since the third term in the fibonacci sequence is 2.
I am not sure how to do this so for my attempt, I used the formula found in this website. A Formula for the nth Fibonacci number
Here is the program so far. It doesn't produce the correct output.

C :: Variable Won't Change When Calculating Factorial In Euler Number Homework
Sep 27, 2014I started to learn programming through this site two weeks or so ago. I've got a book with exercices and so on, and one of them involves calculating e within a tolerance given by the user.
The formula for calculating e is the summation of 1+(1/i!), where i -> n.
So, here's the code and I'll explain the problem below:
Code:
#include <stdio.h>
int main()
{
float error;
float terme;
float sumatori = 0;
int cicle_euler = 1;
int factorial;
[Code]...
For some reason, when I set factorial to cicle_factorial, factorial remains 0, which I find puzzling; the program always halts when 1 + sumatori is 2.0 no matter what error is.
This must be a common problem and I suspect it has to do with some distinction between variables inside a loop and variables outside it, but as I lack technical vocabulary I can't seem to find anything on Google.

b) How many movies and which genres belong to a certain date? The date must be entered by the user.

I've tried to cast (int) before "llista[i][j]" but it says that I'm already supposed to get an integer from that.
C++ :: Incorrect Operands And Undefined Identifier
Apr 25, 2013 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.

C++ :: Algorithm For Permutations Of Operands And Operators
Jun 12, 2014I 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.
Example:
myIntegers = {3, 7, 8, 10, 50, 100};
trgtInt = 315;
Solution is (50 + 10) * 7 - 100 - 8 + 3
We also have the following conditions:
1) Each number from the list can be used only once, but does not have to be used. i.e an expression with 5 or less numbers is acceptable
2) Operators can be used multiple times
I am thinking a parenthesis-free notation like Polish or Reverse Polish notation should be used.
C/C++ :: Invalid Operands To A Binary Expression
Jul 19, 2014I'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).
class VectorClass{
friend vector<float> operator+( const vector<float>&, const vector<float>& );
friend vector<float> operator...
friend vector<float> operator...
private:
...
...
public:
...
And then in my main class looks vaguely like this
#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.
C++ :: Determine Number Of Times Change Each Specific Character In String To Make It Palindrome
Feb 19, 2015I'm trying to determine the number of times I have to change each specific character in a string to make it a palindrome. You can only change a character one at a time from the end.
Example: "abc" -> "abb" -> "aba" should print 2. "aba" will print 0 because it's already a palindrome. "abcd" -> "abcc" -> "abcb" -> "abca" -> "abba" will print 4 because it took 4 changes to make a palindrome.
I'm not too sure how to approach this - I figured out the case where if it's a palindrome (if reversed string is the same) then it'll print out a 0.
int main() {
int number;
cin >> number; //expecting a number for first line user input
for (int i = 0; i < number; i++) {

C++ :: Coin / Money Change Code Doesn't Give Exact Change
Feb 20, 2013My coin/money change code works when there can be an exact change each time, i.e. when the 1 cent option is available. However, when the change options are only $10, $5, $1, 25 cents and 10 cents, it does not give me what I want for instance, I wanted to get change for $237.80, I was expecting to get:
23 10's, one 5, two 1's and 8 dimes. However, the code below is giving me 23 10's, one 5, two 1's and 3 quarters (there is no option left for the 5 remaining cents).how to fix it?

#include<iostream>
#include<algorithm>
#include<vector>
using namespace std;
void change(double cents, int a[]);
int main() {
double Dollars;

C++ :: Namespaces / Classes - Perform Operator Overload With Insertion Operator
Mar 22, 2013I'm doing a refresher for C++ and have gotten to operator overloading. I'm trying to perform an operator overload with the insertion (<<) operator, but I have encountered a problem.
Here's my class [In a header file "Shinigami.h"]
#include<string>
namespace K{
class Quincy;
class Shinigami{
friend std::ostream& operator<<(std::ostream&, const Shinigami&);
[Code] .....
If the operator function is a friend of the 'Shinigami' class, why doesn't it recognize any of it's private members? I need it to be in this file because I'm doing a bit of association with the 'Quincy' class.
I thought it was the namespace, but I included that.
