I have written this bit of code for the Fibonacci sequence.
Code:
9 int size=0;
10 int fib[DWORD];
11
}
[code].....
I have tried quite few things and I am trying to change the prototype for generate Fibonacci to... int* generateFibonacci(size). I have been trying to use calloc inside generateFibonacci and then declare a pointer in main that points at the address of the pointer that generateFibonacci returns.
I made a fibonacci series with label above it now how to put the label after the first layer because as you can see in the screenshot the label is continuous.
I can't seem to get the math portion right. It is supposed to approximate pi using (sigma,i=-1 to infinity)(-1)^(i+1)(4/(2i-1))=4(terms of pi). And what I have does some math but it is incorrect because I get a negative value for pi and one that is entirely too large at that. The precision is also to be at 20 decimal places. I also need it to end immediately after if I get an invalid input, but I can't seem to get it to end after trying a few different things it will say that it is an invalid number, but will continue to run the math loop. I also need the final cout to print all the terms that is multiplied by 4.
[code]#include <iostream> #include <cmath> #include <iomanip> using namespace std; int main() { int nterm, numerator; double sum = 0.0; const int upperBound = nterm * 2; cout<<"This program approximates pi using an n-term series expansion. "<<endl;
My 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?
Code: #include<iostream> #include<algorithm> #include<vector> using namespace std; void change(double cents, int a[]); int main() { double Dollars; double cents;
Write a program that displays the first 40 Fibonacci numbers. A Fibonacci number is created by add the previous two, with the first two always being 0 and 1. A partial sequence is as follows:
0, 1, 1, 2, 3, 5, 8, 13, 21,….
Your table must display 6 numbers per row and use a spacing of 10 for each number. Don’t forget to include the header file “iomanip” at the top and use “setw()”. You will need to turn in an algorithm, source code and output.
Here is what i have but i get errors!
#include <iostream> using namespace std; { int FirstNumber = 0; int SecondNumber = 1; int NumberOfNumbers = 2; int NewNumber;
I'm trying to make a fibonacci sequence with some user inputs. I'm using arrays for this, the user inputs are for the Nth term and the starting number (as in the number in front of 0).
My problem is that when the program runs it's an infinite loop which constantly prints the starting number. Which, I think, means that my WHILE loop isn't coming to an end and my 'count' variable isn't increasing.
#include <iostream> using namespace std; int main() { int start; int term; cout << "Input a starting number for the sequence: "; cin >> start; cout << " Enter the Nth term for the sequence to reach: ";
Is it even possible to store the 100th Fibonacci number (beginning with the numbers 1 and 1) into a variable? I know the number is pretty huge, and wondered if there is a data type to hold a number that big.
#include <iostream> #include <iomanip> using namespace std; #define SIZE 20 void Fibonacci( int ); int main( ) { cout << "How many numbers are in the Fibonacci Series? ";
I am making a program to run Fibonacci series. I have created 2 array.
1)- 1st array holds only 0, 1 2)- 2nd array holds other values eg: 1, 2, 3, 5..........etc
I am using while loop to get the febonacci series and storing it in a 2nd array called int[] numbers.
After getting value using while loop, I am joing both the arrays using int[] final = arr.Concat(number).ToArray();
At last, I have used foreach loop to add the febonacci series into the listbox.
The problem I have is that, I cannot able to concat both the arrays. I tried to assign number array at the top of the while loop. so that number variable will be accessible outside the while loop. But I am getting a error.
See the code below
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms;
We have to write a function named fibonacci that takes an int indicating the length of the series and then store it in an array of size 20 printing the sequence from largest to smallest. Here is the small bit i have so far:
#include <iostream> #include <iomanip> using namespace std; void Fibonacci( int ); int main( ) {
[Code] ....
I just need something to get me on the right track.
I was asked to write a code that has the user input a number and then the computer calculates it for the Fibonacci series. The output should be separated by commas and a period should follow the last number. Ex. 1,2,3,4,5. <---period
I can't seem to get the period at the end. I have the commas and everything else. Here is my code:
#include "stdafx.h" #include <iostream> using namespace std; int main() { double num;
cout << "How many Fibonacci numbers do you want to display?";
The function im having problems with takes an array where each element is an array of unsigned chars i.e. octals representing a bitmap of one of 95 ASCII code characters and searches through this two dimensional array looking for a match for a predetermined of array of unsigned chars i.e. the bitmap of a predetermined char. If we find the char the function outputs the index in the two-dimensional array where each elem. is an array of octals ELSE it return -1 i.e. when the char is not found.
I have 2 files, one .cpp, the other .h. There is a function named find_char. See INPUT and OUTPUT on line 48 in .cpp file.
The exception im getting is: font2.cpp:23:45:error: invalid conversion from unsigned char to unsigned char(*)[5]
The input type specified for my function prototype corresponding to find_char. If I put just unsigned char it doesn't fix the problem because it's an array parameter i.e. like a call by reference. I've lead myself to believe that the array variable contains a pointer to the first value in the array and so I've made function prototypes that work with a T* i.e. a pointer to type T. Making the function prototype argument unsigned char* i.e. a pointer to unsigned char simply gives me the exception: "invalid conversion from unsigned char to unsigned char*". When I have the argument be 'unsigned char' I get undefined reference to find_char(unsigned char). URL.....
#include<iostream> #include<string> using namespace std; int bin2dec(const string binarystring); // Declaration of bin2dec prototype with one string parameter int main() { cout << "Enter Q to terminate program.
[Code] .....
Right now the code is in the form of a 'const string binarystring' and were supposed to be able to use 'const char binarystring[]' and for some reason whenever i try to switch it i run into problems when referencing the main function to the int bin2dec(...) function.
I wanted to know if theres a simple way to switch the prototype to an array type of function with [] without changing the entire code.
#include <ctime> #include <iostream> #include <sstream> #include <string> #include <fstream> class Debugger; class Debugger {
[Code] ....
My question is regarding the GetCurrentDebugLevel function above. Ideally I would like to use just one function to get the current debug level of the class, the std::string form would be used to save the "debugging level" in a settings file and the enumerated version would for evaluation purposes throughout the program.
My question is if implementing function prototypes by return value the best way to go or should I do something else?
#include<iostream.h> #include<conio.h> int main() { setcolor(BLUE); setbkcolor(yellow); cout<<"the text in blue colour with yelow background"; getch(); return 0; }
it keeps returning the same error always in my turbo c++ compiler . What is the correct program for changing background colour and text colour ...
Variably modified types are subject to certain restrictions , just as variable-length arrays are. The most important restriction is that the declaration of a variably modified type must be inside the body of a function or in a function prototype.
Code: void f(int m , int n) { int a[m][n] , (*p)[n]; p=a; //.... }
What does it mean? That we can't declare such a pointer as a global variable?
