C/C++ :: Calculate Sum For Input Values Of X And N
Feb 27, 2015
I added my assignment to attachment, i need to calculate the sum for input values of x and n this is my code:
#include<stdio.h>
#include<math.h>
main() {
float gore,dole,s,x;
int n,i,j,z;
s=0;
i=0;
j=0;
[Code] ....
gore calculates x^(2*i)-3 and dole is for (2+i)! for input x=1 and n=1 i get -2.0 output which is the value of x^(2*i)-3 the (2+i)! part gets ignored for some reason, for any other input i tried the output is 0 ....

I have this code that im stuck on what i need to do is Extend the code such that when it starts the user is asked to input values to specify each of the three ranges before moving on to accept and tally the main values how do i do that Using a for loop to input and output array values Also calculate the average
*/
#include <stdio.h>
int main(void)
{
/* Declare an array of integers */
int Grades[5];
int nCount;
int nTotal = 0; /* Declare and initialise the value */
float fAverage;
[Code]...

So I have to make a program that allows the user to enter both positive and negative numbers and the program is suppose to calculate the sum of only the positive values while ignoring the negative values. Also it is to be a sentinel-controlled loop with a number ending the set of values.

I'm trying to calculate the size of values I've dynamically allocated memory to, i.e.
col_ind = new long[nz];
row_ptr = new long[inrows+1];
val = new double[nz];
from pointers. Now I've created the function,
int getmemsize(int i) {
int sizes[3];
sizes[0] = sizeof val;
sizes[1] = sizeof col_ind;
sizes[2] = sizeof row_ptr;
return sizes[i];
}
but each one is returning just the value 4? My arrays (one example) look like:
val = [ 5 2 5 9 8 3 9 10 9 ]
col_ind = [ 0 1 1 ]
row_ptr = [ 0 2 3 ]

I am trying to create a simple interface on console to allow to input some values to some variables. For ex:
int main() {
double a = 1.5;
double b = 2.5;
double c = 3.5;
string x;
[Code] ....
However, I want these three to display at the same time (now they display one by one), and in the console window I can move the cursor between input place of a, b and c with "arrow key" of keyboard.

I am attempting to create a program which calculates the product of 4 vertical values in the matrix. The numbers are supposed to be randomly generated and the size of the matrix is given through the command window.
However I seem to have either not pointed my matrix through all of my functions correctly, or my logic is off somewhere as I keep getting this output regardless of the size of matrix I put in:
"the location of the highest horizontal line product is: 5 0 and is the number: 0
The overall max value is 4196352 at the above coordinates."
using namespace::std;
//srand(time(0));
int h_line(int**, int, int);
int v_line(int, int,int);
int diagnol_left(int,int,int);

I'm trying to calculate the number of distinct values entered into an array. If i enter the followings "3,4,5,6,7,7,6,e (anything that's not a number)" . I get a total of 7 but in reality it should be a 5.
Code:
#include <stdio.h>
//---------function to find the distinct values----
int find_distinct(int list[], int size)
{
int i, j,size2, distinct = 0;

I am having trouble with calculating the volume of a cone
Assignment: Using the knowledge you already have, create, build, run, and correct if necessary a program that will calculate the volume of a cone. Insert into your code values for diameter of the base and the height. Use variables, constants, literals, and mathematics as necessary.
The formula for the volume is:
1/3 π x Radius2 x Height
Hint: you will need to add to your program two lines where appropriate:
#include <cmath>
const double PI = 2*acos(0.0);
Here is my current code:
#include <iostream>
using namespace std;
int main () {
//diameter of the base
float diameter = 3;

I am trying to make a program that will calculate gpa using a transcript from an input file. The transcript includes the title of the subject, the letter grade, and the credits per class. However, I wouldn't know how many courses are in the file. How would I start to write out this program? The only things I can use are ifstream, ofstream, for-loops, if statements, and if-else statements.

I am trying to create a program that will calculate pi based on a user input for accuracy. If the user input .3 then when the leibniz infinite sum value at a particular i becomes less then the input of .3 then the loop will exit.
I have looked at a number of examples on the internet but I feel lost. I have put together working code that will infinitely output sums but I need the loop to stop when the sum value is less then the accuracy value.
My question is what is wrong with my while loop, why will it only give me infinite summations? How do I make it so that the loop will exit when my accuracy input is greater then the sum?
int main () {
double accuracy;
cout<<"Give an accurate number." << flush;//looks nice
cin>>accuracy;
int d;//initialize denominator
double pi = 0.0;
while(accuracy < d){

I'm trying to create a program that will take input from a user and calculate it in a do-while loop. The program does the calculation but the answer is wrong. The loop also doesn't work. The purpose of the program is to see how much an item will cost after a discount is taken off and tax is added.
#include <iostream>
#include <cmath>
using namespace std;
double original_cost;
double discount;
double tax;
double total;

I have created a program to calculate different measurements for a cylinder. Anyways, the end user has to input 3 variables.
Enter the lower radius: 6
Enter the upper radius: 5
Enter slant height: 2.236
The numbers are what "End User" would input. But I need to make it look like this when said "End User inputs the numbers.
Enter the lower radius: 6
Enter the upper radius: 5
Enter slant height: 2.236
Here is what I have for it, but I don't know what to put where.
printf("
Enter the lower radius: ");
scanf("%f", &lower_rad);
printf("Enter the upper radius: ");
scanf("%f", &upper_rad);
printf("Enter slant height: ");
scanf("%f", &slant_h);

I'm still fairly new to c++ and am having trouble with dynamic arrays. My task is to create an array for test scores. The user needs to define the size of the array and then input data to later sort and calculate the average.
Below is what I have so far. I am struggling with the user input part. I receive the following errors for the data input of the individual scores:
"error C2108:subscript is not of integral type"
"IntelliSense:expression must have integral or unscoped enum type"
Code :
#include<iostream>
#include<iomanip>
using namespace std;
int main() {
//user input total number of scores
cout<<"Please enter the total number of test scores."<<endl<<endl;

I need my program to read a list of numbers from and input file, random.txt, and calculate the following statistics on those numbers:
A. The number of numbers in the file.
B. The sum of all the numbers in the file.
C. The average of all the numbers in the file.
D. The largest number in the file.
E. The smallest number in the file.
#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>
[Code]......
This is what I have so far but I'm not sure if it is right. I can't get the input file to open.

I am trying to code a program that takes in user inputted data about percentages and using it to later on calculate a final grade. 4 percents are inputted, for Assignments, Midterm1, Midterm2, and Finals. If the percents dont add up to 1 (i tell the user to enter the decimal value) I set up and if statement to catch it and end the program. Except that if i type in
Assignments = .3
Midterm1 = .3
Midterm2 = .3
Finals = .1
the program doesn't recognize that they add up to 1. Heres the relevant portion of my code [URL] ....
Here's some examples of how it works [URL] ....
And heres what i dont understand [URL] ....
Why is it saying .3 + .3 + .3 + .1 != 1 when .1 + .3 + .3 + .3 == 1?

I'm trying to make a c++ program of this but i don't know how to use the bubble sorting.
Write a C++ application that asks the user to enter 10 numbers. The program then stores those numbers in an Array. The program should display the Mean , Median, and Mode.
Mean is the average of the 10 numbers.
Median is the average of the 5th and the 6th numbers. (But you have to arrange the numbers in ascending order first using Bubble Sort before calculating the Median.)
Mode is the most frequent number among the 10 numbers.

I have a problem with how to print out all the numbers that the user enters the code looks like this so far:
Code:
#include <iostream>
using namespace std;
int main()
[Code] ....
I want the program to print out all the numbers that the user has entered after the program have said the higest and lowest number is ?. But I do not know how to do this I thought it could be something like this:
Code:
cout << input[0];
//or
cout << input[i];
/*
Because i is the number of how many enters of numbers the user can do*/ But that was totally wrong tried to do another "for loop" in the first for loop but that was meaningless because it can't change anything in the first "for loop".

Same solution that I was having compiler errors on yesterday. We're working with inheritance and the program is supposed to be to create and display information for default Employee objects, Hourly Employee objects and Salaried Employee objects. Everything compiles as is, but I'm running into two issues that I can't figure out.
1) In both the hourly and salaried objects, the wage, hours, and management level attributes all displaying their default values. I'm almost positive that this has something to do with the str to int and str to double conversions that I'm using (currently have atoi and atof in the file, but I've also tried stringstream, but still had to same problem). Any thoughts as to what I'm missing?
2) the assignment calls for the Benefit benefit member in Employee.h to be protected. However this makes the member unaccessible when I try to use it in the EmployeeMain.cpp in order to set the input for the Benefit class members. I had to make the Benefit benefit member public again to get it to compile. How would I set the input for the Benefit class members while the Benefit benefit member is protected?
Solution files follow:
EmployeeMain.cpp
Code:
#include "Hourly.h"
#include "Salaried.h"
void DisplayApplicationInformation();
void DisplayDivider(string);
string GetInput(string);

What "int values" is supposed to mean as parameters to these functions? I'm not sure what do with them. Also how to input values into the array via functions. I was trying to but I just don't understand how to connect a user's input to a function to then enter into an array.
// input reads “values” integers from the user to place in the array data. It prompts the user for each value individually with the ordinal position of the value.
void input (int data [size], int values);
// Places the sum of corresponding values from arrays a and b and places the results in array s. The first “values” integers in the array are processed.
void do_sums (int a [size], int b [size], int s [size], int values);
