Write a recursive function called sumover that has one argument n which is an unsigned integer. the function returns double value which is the sum of reciprocals of the first n positive integers =.
for example sumover 1 returns 1.0
sumover 2 returns 1.5 like 1/1+1/2
Write a program with two functions both called from main(). The first function just prints "Hello". In the second function ask the user to enter a number. Calculate the square root of the number and return the result to main(). In main() print the square root value.
Ok so I am working on a game and I'm in the process of developing my Player class. Anyways, what I have is a keyboard function that is called in my main function to make a shape move.
void myKeyboardFunction(unsigned char key, int x, int y) { switch ( key ) {
[Code].....
But when I try to call it, trying to copy my previous method,
glutKeyboardFunc(Player1.playerControls);
I get an error
error C3867: 'Player::playerControls': function call missing argument list; use '&Player::playerControls' to create a pointer to member
I get an error saying it can't convert parameters. I would just like to understand why the arguments become a problem when I make the function a member of my class, when the first method I used is so easy.
I am working on this project where I need a function to be called every second. At this time, I am thinking that I have to create a thread but I am clueless on how it will get called every second.
When I call printStuff, the DerivedClass's function gets called. Now, if I remove the const part from the DerivedClass's printStuff function, we call the BaseClass's printStuff function.
There is already a thread with exactly the same problem I have, but the answer to solve the problem isn't stated at the end. Problem with callback as classmember.
As I am taking my first steps in C, I study K&R (I guess most of you did the same, right?)
In the introductory chapter about functions (1.7) there is an example showing how to create a function that is then called to calculate powers (b**n). I simplified it to calculate only one given power, 2**5:
Code:
#include <stdio.h> int power(int m, int n); main() { printf("%d", power(2,5));
[Code]....
It will then be called to make the calculation in the above string.
First things first: we already know how to use while(getchar!=EOF) to count characters (K&R chapter 1.5.2) but what if -instead- the input is a specific string? How to "read" it and how to tell my program that the string is finished? And most important: "reading" will be done in the function or in the rest of the body?
So on lines 36 - 39 (The commented out functions) is where I'm sure is causing this error because once I don't comment them out pretty much everywhere Flink or Rlink is used or defined I get this error.
How to find the size of an array in called function? When we pass the array a argument to function definition we will be having base address of array, so my understanding is that we will not get the size of an array? but is there any hacking for this to find size of array other than passing as size an argument to this called function?
I'm currently making a game and what happens is that during runtime, it suddenly closes and a message is shown in the console saying "Pure virtual function called at runtime".
Here is the code: [URL]
The problem seems to occur somewhere between lines 662 - 695. And it seems to only happen when the size of the vector reaches 1.
I have a function and i want to delete a file when the function is called and starts it's loop i have used this code but unfortunately the file is not deleted ?
Code: void evaluate(void) /*evaluate the population */{ int mem; int i; double x[NVARS+1]; char buffer[101] = {"save.txt"};
My program seems to be working fine, except for when I call on my delete function. I don't receive any errors, but when I call the delete function my program outputs nothing and freezes. As in, my print function (which is called before the delete function) doesn't even work. I've tried removing bits of the function to see if I could pinpoint where exactly the issue is, but I've had no luck.
#include <iostream> #include <string> using namespace std; class List{ private: struct node{ string _data;
[Code] ....
And the function that is causing me trouble:
void deleteNode(string data){ node* del = NULL; t = h; n = h; while(n != NULL && n->_data != data){
I've created a function where you can choose any bounds for an array based list (positive or negative, as long as the first position is smaller than the last position). However for some reason when I call the print() function in my application program it doesn't do anything. My print function is technically correct (I still have work to do on the output) but I can't figure out why it wont show anything at all. Below is my header, implementation, and main program files, along with results from running the program.
The recursive function is bolded, i got feedback and was told that the static variable made the function seem a lot like a iterative function but he did not say why.
Code: #define MAX 100 #include <string.h> #include <stdio.h> int checkPalindrome(char string[MAX]); int checkRecPalindrome(char string[MAX]);
the functions checks if the word is a palindrome like"level" "madam" etc. but with input "dfdfdfdffdfd" my recursive function fails.
Code:
/* main.c - Created on: Nov 9, 2013 - Author: Kaj P. Madsen*/ #define MAX 100 #include <string.h> #include <stdio.h> int checkPalindrome(char checkString[MAX]); int checkRecPalindrome(char checkString[MAX], int strLgt, int a); }
[code]....
results from "dfdfdfdffdfd" added some print to see that its the variables a and strLgt not functioning properly
Code:
dfdfdfdffdfd. The word is not a palindrome(iterative) strLgt: 11 a: 0 a: d strLgt: dstrLgt: 10 a: 1 a: f strLgt: fstrLgt: 9 a: 2 a: d strLgt: dstrLgt: 8 a: 3 a: f strLgt: fstrLgt: 7 a: 4
I am just practicing some recursion and I am having trouble with printing out a recursive function in main. Here is what I have:
Code:
// This function adds the squares 4, 5 = 4*4 + 5*5 recursiveley int recursive_sumSquares(int m, int n) { if (m < n) { return m*m + recursive_SumSquares(m+1, n); } else { return m*m;
[Code]...
I am getting an error that says undefined reference to 'recursive_SumSquares'
I am working on a problem that requires a nest for loop to be converted to a recursive function. I am going to provide just the code instead of the entire program.
Code:
for (R1=1; R1 <+3, R1++){ //for loop printf (something); } // the recursive function void loopR1 (int R1, int max){ if (R1 <= max){ printf (something);
[Code]...
when calling the recursive function in main i am using the following statement...
