C++ :: Function That Accepts Array Of Integers And Its Size As Arguments
Feb 12, 2014
Write a function that accepts an array of integers and its size as arguments. The function should create a new array that is one element larger than the argument array. The first element of the new array should be set to 0. Element 0 of the argument array should be copied to element 1 of the new array, element 1 of the argument array should be copied to element 2 of the new array, and so forth.
The function should return a pointer to the new array. Use ONLY pointer parameters instead of arrays in both functions; use pointers (not subscripts) to move through elements of both arrays. Before calling the function, display your original array. When the function call is completed, display the new array.
Here is what i got so far:
#include <iostream>
using namespace std;
int *shifted (int * , int);
const int SIZE = 10;
int main () {
int array_size [30];
write a function accepts two arguments, an array of integers and a number indicating the number of elements in the array. the function should recursively calculate the sum of all the numbers in the array. Demonatrate the use of the functions in a program that asks the users to enter an array of numbers and prints it sum
i had done this but it wont work
#include <iostream> #include <conio.h> #include <iomanip> using namespace std;
The lambda accepts no arguments, but it accesses increment by value and current by reference, the latter being used to store the next value to be set. This lambda has the side effect that current will be updated when generate is finished. The following lambda expression is similar, but without the side effect:
[=]()mutable->T{T result(current); current += increment; return result;} "
I dont exactly understand what side affect it is talking about. Wouldn't you want generate to update current? I understand how the second code fixes it though, just takes everything in the enclosing scope by value.
Write a program using user-defined function which accepts an integer array and its size as arguments and assign the elements into a two dimensional array of integers in the following format: If the array is 1,2,3,4,5,6, the resultant 2D array is
In class, we have learned how to set up the main method so we can convert command line arguments to integers and utilize them. Here is an example of a method we learned to store command line arguments as integers in an array:
Code: int main (int argc, constchar* argv[]) {int i; int a[argc - 1]; // Fill the array with the arguments on the command line for (i = 0; i < argc - 1; i++){ a[i] = atoi(argv[i + 1]);
[Code] .....
I understand that there are probably better ways to do it than using the atoi function, but for our purposes, the professor said this was okay.
Now, I am being asked to create a separate function to perform the same task (store integers in an array). I was told I would need to declare the array "out in the main program", and that the function would need to take at least 2 arguments: an array, and an array size.
Firstly, what should my return value be? My professor gave a hint that it would be important for me to figure out what the return value is, but I don't see why it would be anything else than void.
Also, wouldn't I need a third parameter? Perhaps the integers that are being stored in the array? (But how would I represent this as a parameter)?
I was trying to code a program that accepts your first name and then last name and then displays it through another function. I have checked that the assignments are between similar type of variables and pointers, but I don't seem to get it right.
When first input is taken and then second one, the first one's value changes to same as the second. E.G if first name is L and second name is S and after second input both variables, first and sec, become equal to S. Why?
How to go about making a function that accepts an integer and returns a string with any one of 5 strings containing the name of the object. For example object number 3 might be "Pen". Object 4 might be "Paper".
Here's the question: Create a program that accepts an array of characters. And displays the converted array of characters into Upper case if it is given in Lowercase and vice versa. Don't use string, but char.
Example: mychar ="I am A conQUeror." Code: //My Codes: #include <iostream> #include <conio.h> using namespace std; int main()
void foo(const double va, const int q) { int qaa[q]; ...... return; }
However, the compiler indicates allocator cannot allocate an array of constant size 0... how can I use the argument "q" to fix the size of array "qaa"?
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 am having trouble getting the stars to output correctly in the printStars function. the final output should look something like this:
#include <iostream> using namespace std; int readArray(int input[], int size); void printArray(int input[], int count); void printStars(int input[], int size);
I'm working on a piece of code written long time ago. Without getting in the details or too much context here, there is a function that declares an array of char of a size of 350,000 elements, in order to fill it (using a pointer) with the list of all running processes on the machine (using "ps -ejf" on a Linux box).
The size of the char array has been changed from 40,000 to 350,000 sometime along the years, probably because of a lack of space required.
What kind on data structure / storage would you use to store the running processes in order to eventually search for a value in it?
I have a struct called Array and I'm to create a function to create a dynamic array that's fill with randomly generated integers from 0 to 50 (inclusive) and a function to destroy the array for freeing its memory. Below the code that I have written so far.
Code:
* Struct */ typedef struct {int *pArray; //the dynamic array int length; //the size of the dynamic array}Array; /* Function to create a dynamic array */ Array *initializeArray (int length) {int i; }
Example radix sort function to sort an array of 64 bit unsigned integers. To allow for variable bin sizes, the array is scanned one time to create a matrix of 8 histograms of 256 counts each, corresponding to the number of instances of each possible 8 bit value in the 8 bytes of each integer, and the histograms are then converted into indices by summing the histograms counts. Then a radix sort is performed using the matrix of indices, post incrementing each index as it is used.
Code: typedef unsigned long long UI64; typedef unsigned long long *PUI64; PUI64 RadixSort(PUI64 pData, PUI64 pTemp, size_t count) { size_t mIndex[8][256] = {0}; /* index matrix */ PUI64 pDst, pSrc, pTmp; size_t i,j,m,n; UI64 u;
I am doing a problem where I need to use arrays of string objects that hold 5 student names, an array of one character to hold the five students' letter grades and five arrays of doubles to hold each student's set of test scores and average score.
When I try to run it, I get these five errors.
error C2660: 'getTestScore' : function does not take 3 arguments : line 39 error C2660: 'getTestScore' : function does not take 3 arguments : line 45 error C2660: 'getTestScore' : function does not take 3 arguments : line 51 error C2660: 'getTestScore' : function does not take 3 arguments : line 57 error C2660: 'getTestScore' : function does not take 3 arguments : line 63
I am a bit confused about how specific one must be with arguments when declaring a function. I'll show you two functions from the book I'm using to learn C to show you what I mean.
Example 1 (greatest common denominator function):
Code: void gcd (int u, int v) { int temp; printf ( "
[Code] ....
So in that function, there are exactly two arguments, because that's how many arguments the algorithm to find the gcd takes. No problem there, makes sense to me. Then further in the chapter on functions I run into this,
Example 2 (square root function):
Code: float absoluteValue (float x) { if ( x < 0 ) x = -x; return x;
[Code] ....
In this second example, we have a square root function that is preceded by an absolute value function. The absolute value function has the one argument, "float x", however when this function is called within the square root function, the arguments "guess * guess * -x" are passed to it. I'm confused how this absolute value function is working with all of that inside it, when it was originally declared with just "x." The only possibility I can think of is that this expression is treated as a single unit, but I'm not sure.
I am actually developing an nginx module in C.I am not to bad in C, but i got a big problem to pass argument to a vadiadic function.This function look like the well good old printf, but you put a buffer as first argument, the last address to stop to put data as second argument (in my case it is the last adress of disponible memory), a string that look like one in printf, an the other argument after.Here is the problem, the 4th last argument does not have the good value. In fact, It seem to be random value from memory. I Use gcc (Debian 4.9.1-19) 4.9.1.
I'm trying to create a callback wrapper for pointers to member functions of any class by using templates, std::function and std::bind. This will be used to send incoming sf::Event's to classes who register callbacks with an event manager. I based my code off of the example on this page: URL.....Here's what I have:
class EventCallback { std::function<bool(const sf::Event&)> func;
How this code work bcoz when pointer variable assigned in called function and how different values get as resultant output, ans 2 97 for below code. How the code wil execute so that i can validate ans
#include <stdio.h> int main() { int i = 97, *p = &i; foo(&i); printf("%d ", *p);
What I have is a main function that takes input characters from the command prompt during the main function call, and coverts it to an integer array a using atoi. (starting at the 2nd character - the 1st is reserved for another call that I plan to reference later, and the 0th is obviously the ./function). A function is then called to find the mode of an array (the range of values in the array is 1-30). Now, when I run the whole thing, I get a segmentation fault (core dumped) for even number of arguments. It's late and I've been staring at it for too long...
Code: #include <stdio.h> #include <stdlib.h> int get_mode(int a[], int count);
I'm not a programmer, at least, not a good one. I'm a researcher and I need to implement this function and test it and use it for my research. I tested some clustering methods in JAVA and Matlab and also I want to test it on C. I don't know too much about programming, especially about C, I know nothing. I tried to implement some basic methods but I failed.
It's all about K-Means Algorithm. I'm working on a disease and I'm trying to find ways to early diagnosis. Anyway, these are details. The thing is, I found a 'free to use' function but I don't know how can I use it. I tried to learn something from Net, I downloaded a compiler, I paste the code and I get many errors... And I heard that I have to do some "calling function" stuff but I don't know how to..
The code is in the link below: URL....It's not imperative that using this function, it can be another one but it had to written in C.
error C2660: 'Add' : function does not take 0 arguments error C2660: 'Subtract' : function does not take 0 arguments error C2660: 'Multiply' : function does not take 0 arguments error C2660: 'Divide' : function does not take 0 arguments
