My program thus far is: (omitted code to shorten post and remove irrelevant information.
I don't know if it is because I have been working on other things and forgot how to proceed with the calculations and display, but I am just stuck. I'm not sure how to have the program read the numbers from columns 2 through 5 and then divide by 3. As you can see in my DisplayAverages() method I should have the ConsoleWrite and WriteLines done properly.
Write a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: Each line contains a student's first name, then one space, then the student's last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file. The data in the output file will be nearly the same as the data in the input file except that you will print the names as last_name, first_name and there will be one additional number at the end of each line: the average of the student's ten quiz scores.
The output file must be formatted such that first and last names appear together in a left justified column that is 20 characters wide where the last name comes first, then a comma and a space and then the first name. Use your read string function to read each name separately and then put them together into a larger correctly formatted string before trying to output them. Each quiz score should be listed in a right justified column that is 4 characters wide, and the average should appear in its own right justified column that is 10 characters wide.
Note that if a student has fewer than 10 scores, the average is still the sum of the quiz scores divided by 10; these students are assumed to have missed one or more of the quizzes. The output file should contain a line (or lines) at the beginning of the file providing appropriate column headings.
When I compile my code with g++ I get the error: constructor, destructure or type conversion missing before sum.
int sum(int,int); void sum(int,int,int&); main() sum (v) // This is the line that the compiler is reporting the error occurs. answer sum() int main(){ int a=1; int b=2; int sum;
The bottom three functions do not work. Nor are the finished to the extent. I do not know how the data members are being accessed and is only giving me the last output. The overall goal of this program is to output the highest grade with student name and age, lowest grade with student name and age, and the average of all grades. The file is given and is commented out for you to see what the file looks like.
// Header Files #include <iostream> #include <fstream> using namespace std; // Global Constants const int STD_STR_LEN = 10;
How to traverse through this array and output each student and score that falls below the average. I think I may have the method down for traversing through the list to find the "total score" however, before proceeding under a possible wrong presumption, I would like confirmation as to whether or not I'm understanding this or botching this concept.
void dispLowScore(struct payload *arrayStart , //first element of array struct payload *arrayEnd ) //last element of array { int studentCount; //total number of students in list/array int totalScore ; //accumulated value of all scores added together float averageScore; //totalScore / studentCount
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;
I have a project that I am working on and I have gotten stuck. I am getting a couple errors and would like to see how I can complete the program. Not very long of a program at that. My instructions are:
Write a program to calculate averages. Create a method named ReadData that will load a two dimensional array, named scoresArray, with the following data from a file:
Create a method named DisplayAverages that will display the emplyee number (number starting 1324, 4356 etc) and the average of the three test grades. DisplayAverages will have one argument, the scoresArray. Your output should closely resemble the following.
Round averages to one decimal place. Passing arguments is important for this program. No global variables are allowed, except for the streamReader and the streamWriter. The scoresArray must be declared in Main and passed as an argument to the methods ReadData and DisplayAverages.
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using LibUtil; using System.IO; using System.Text.RegularExpressions;
[Code] ....
When I run the following just to see where I am getting I get the following error:
UsersJoeDocumentsVisual Studio 2013ProjectsCIS110Program12Program12Prog ram12Dat.txt was opened Unhandled Exception: System.IndexOutOfRangeException: Index was outside the boun ds of the array. at Program12.Program.ReadData(Double[,] scoresArray) in c:UsersJoeDocument sVisual Studio 2013ProjectsCIS110Program12Program12Program.cs:line 66 at Program12.Program.Main() in c:UsersJoeDocumentsVisual Studio 2013Proj ectsCIS110Program12Program12Program.cs:line 24 Press any key to continue . . .
What am I missing here? I believe I have passed the arguments properly, but I am unable to declair the array within the bounds of the array?
Write a C++ program to output information for three students. The information stored in your program contains student’s first name, middle name, last name, and test score. The following shows the information for the three students, where test score is in the int type.
John Jacob Smith 78 Mary Jane Weems 82 Dave Joe Dale 61
Your program should declare three named string constants for the three students. Each constant contains the student’s first name, middle name, and last name. You may use three int variables to hold values for the three test scores. The first name, middle name, and last name of a student are then extracted using the substr() function shown in class. Your program should also compute the average (in floating-point number format) for the three test scores. The average score computed should be printed to the screen with 2 digits displayed after the decimal point.
The following shows the output from the program. Note that all the output is left-justified with 15 character positions reserved for each.
first name middlename lastname testscore average John Jacob Smith 78 73.67 Mary Jane Weems 82 73.67 Dave Joe Dale 61 73.67
my code is working as expected except a slight error, i have to find min max and median values of an inputed array terminated by 0, the problem im having is with calculating the minimum, where when i enter 0 to terminate the program it uses 0 as the minimum value. my code is as follows
I have two doubts in the following code,the doubts are marked..PLs note that the following code is correct .This is a program to read 2d array using pointer ()i.e Dynamic array ,to calculate its rowsum and column sum and display this array along row sum and column sum.
#include<iostream.h> #include<conio.h> void main() { clrscr(); int *Val,*Rsum,*Csum; int MaxR,MaxC,i,j;
I need to calculate how often each letter appears in a text file from a function that is called from main() with an array of pointers to char and how many pointers there are in the array. The code i have so far is:
I get no errors and it runs but it gives me the wrong output. I know my array is correct because when i print it in main() it is correct but each letter is incorrectly counted. When i give it the input .txt file of:
This is one line of a string This is another This is the third one Wow heres another one It counts a as 8 b as 1 c as 3 etc.
I have hand traced it and cant figure out why it isnt giving me correct values
I must write a function that has a one dimensional double array and the number of values in the array as its arguments. Normalize the values. I must also print the maximum, minimum, average and numbers of values above the average in the array.
The equation that computes the normalized value from a value x is:
My code does not print the correct normalized value, average and values above average.
Code: #include <stdio.h> int findMax( double array1[], int num_elements) // This function computes the maximum value of the array { int i, max=-32000; for (i=0; i<num_elements; i++)
array is a one-dimensional array of integers and n is the number of elements in that array that contain valid data values. Both of these are input parameters to the function. The function must calculate 1) the average of the n integers in array, storing the result in ave; 2) the average of the positive numbers (> 0), storing the result in avePos, and 3) the average of the negative numbers (< 0), storing the result in aveNeg.
void avgs (std::vector &array, int &ave, int &avePos, int &aveNeg) { int sum = 0, pos_sum = 0, neg_sum = 0, pos_count = 0, neg_count = 0; for (auto i : array) { sum += i; if (i > 0) { pos_sum += i; ++pos_count; }
I am attempting to write a program that takes a number(picked by the user) of test scores in an array then calculates the average and outputs the number of passed and failed tests.
On a side note I am attempting to use array notation in the main function and pointer notation in the other functions
#include<iostream> #include<iomanip> using namespace std; int numScores; int counter = 0; double *scores; //Function Prototypes
I was trying to make a program that asks the number of grades, get the grades and then get the average. I know I have to save the grades in an array but i don't know exactly how.
I am getting the hang of it pretty well. I created a program that asks the user to input arrays. Now, I need to calculate the average of the inputted arrays, and I need to place them in order from low to high. I have been struggling with doing these two parts for a while now and now decided that the book is not useful, I need some from some actual programmers. I attached my program.
My program printed here!
Code: #include <iostream> using namespace std; int main()
i wrote following code to calculate average of the values entered to the array.After displaying the output following error was displayed.
"Run-Time Check Failure #2 - Stack around the variable 'marks' was corrupted.
A buffer overrun has occurred in q 3 410005111.exe which has corrupted the program's internal state. Press Break to debug the program or Continue to terminate the program. "
//Average mark of student 1 cout<<"Avarage mark of the student 1 :"<<(marks[0][0]+marks[1][0]+marks[2][0]+marks[3][0]); cout<<endl;
i'm having trouble trying to make this code works .. the program must repeatedly asks user for the age of a person until user enters -1 ,, once he/she entered -1 the program calculates ( smallest value entered, largest value , and average )excluding -1 from calculation
i've been working on this for a weeks this is the best i could do.i know average must add all the entered values , not only smallest and largest but how can i do that here ?
Code:
#include<stdio.h> int main(void) { int age ; int v; int counter; int l=0; int s=0; int limit; }
I have written two separate programs; Program 1 calculates the average of an array of numbers which has been hard-coded into the program. Program 2 reads an array of numbers from a text file and displays them on the output.
I wish to combine these two programs into one by making Program 1 read the array of numbers from the file and then calculate the average using that instead of the array { 84, 92, 76, 81, 56 } as outlined below. I only wish to display the average in the output, not the number array as Program 2 does.
I have tried to do most of the work, I just need modifying the code slightly so it reads the number array from the file and calculates the average.
Program 1
#include <iostream> #include <cmath> #include <math.h> #include <fstream> #include <string> #include <numeric> using namespace std; int main() { const int nNumStudents = 5;
I am facing a problem which i could not obtain the total numbers which is greater than the average value. For example:
#include <iostream> using namespace std; int main (){ int size , count; double no, max, min ,total, sum , average;
[Code] ....
In this case im able to compute the average of the numbers but when it comes to capture the total of numbers which is greater than the average value, how to compile the code , because the average number is only been compute once all the value capture by the input of user is sum up.
I am attempting to write a program " that has a function that is passed an array of int and its size, and with that it prints out only the numbers that are above average. "
I have included my code so far, but I am only getting one value as output, and that value seems to be completely off. I keep trying, but I am really stuck.
#include <iostream> using namespace std; int average(int values[],int size); int main(){ int size; int values[] = {1,2,3,4,5,6};
[Code] ....
Added the floats in the average() function. But there is still a value problem.
