Write a template that accepts an argument and returns its absolute value. The absolute entered by the user, then return the total. The argument sent into the function should be the number of values the function is to read. Test the template in a simple driver program that sends values of various types as arguments and displays the results.
#include <iostream>
using namespace std;
template <class integertemplate>

How can i come up with a program that uses entered radius of a circle to find its area

r^3 = d*p/s*π
r is the radius of the cylindrical rod in inches. d is the length of the crank arm in inches. P is the weight placed on the pedal in lbs. S is the stress in lbs/in2
Using this information, design, write, compile, and execute a C++ program that computes the value of r for a crank arm that is 7 inches long, accommodates a maximum weight of 300 lbs, and is able to sustain a stress of 10,000 lbs/in2.
I am drawing a circle using ellipse because there is no explicit command for this.
Code:
pDC->Ellipse(CRect(70, 170, 300, 400));
What is the centre of circle and what is radius in the above command?
My problem is the following : We have a circle paper of radius R. We will cut off a sector of this circle (with length rem_sec), and the remaining (bigger part) will create a cone. Radius of cone base is r.
I need to create a code that prompts the user to enter circle's radius R and the program will calculate the length of removed sector (rem_sec) so that the created cone has the Max Volume.
I wrote the following code, but it doesn't work. It displays both rem_sec and MaxV = 0.
#include <iostream>
#include <cmath>
#include <iomanip>
#include <conio.h>
using namespace std;
const double PI = 3.1415;
int main() {
double rem_sec;

myclass(int* p) {MyPointer = p; myclass()}

it works until the myclass(int* p) calls myclass()
then the MyPointer will become CCCCCCCC (NULL value)!
is there a way to stop the second constructor from resetting the pointer value to null?

View 1 Replies View RelatedI 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?

I built a program that accepts two input from the user, using a array inside a loop, it is pass to a function inside a class which will display the two number, the problem is when the user is inputting a number and it is 1 the program continuously as the user to input a number, and when 2 is entered the program ask another number and end, but for example you entered 2 and 3. . . it will then outpu 2 and 4 (so 3 + 1 ) and always the last number is plus one. here is the code.

I have a N queens (actually 8 queens to be specific) program that accepts the numbers in order by row. I need to get it so it accepts the numbers in order by column. At first glance I thought it was just one space different, but it turned out not to be and how to get the one space difference in there. My current code (which I'm aware isn't doing the column accepting right) is:
Code:
#include <iostream>
using namespace std;
int main() {
int board[8];
cout << "Enter the columns containing queens, in order by column: ";
for(int i = 0; i < 8; ++i) {
cin >> board[i];

What the output should be:
Code:
Enter the rows containing queens, in order by column:

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".
To do this would I just use an array?

You pros are once newbies like us. Hoped you might take a little time sharing your expertise. Got freaked out when our teacher gave us this activity, where she haven't taught this to us yet. So this is the activity (LOOPING) :
Write a program that accepts a positive integer. The program should be the same from the given output. Use do while to allow the user to continue or not.
OUTPUT must be:
n = 5
0
1==0
2==1==0
3==2==1==0
4==3==2==1==0
5==4==3==2==1==0
if n = 6
0
1==0
2==1==0
3==2==1==0
4==3==2==1==0
5==4==3==2==1==0
6==5==4==3==2==1==0
I've been tasked with righting a program that accepts three images and combines them into a panoramic view I'm having trouble getting started?
View 2 Replies View RelatedWrite 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];

In this code:
// Ex10_15.cpp Using lambda expressions
#include <algorithm>
#include <iostream>
#include <iomanip>
[code].....
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.
