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.

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.

Code:
#include<stdio.h>
int calcAbvAvg(int marks[10], int avg) {
int students = 0;
int i;
for(i=0;i<10;i++)
[Code] .....
I suck at function and linked list. The only problem i am having in this question is the function calcAbvAbg() not working! I want that function to display the students who are above and below average!
I have learnt about string class, file I/O and pointers. Now I am asked to write a program that includes the above topics, basically testing the ability to use dynamic arrays.
I've got 2 documents, namely "Students.txt" and "EnrollRecords.txt". "Students.txt" includes 40 students' info, which are university ID, programme names and their names. These 40 students are all BEng but from different departments.
E.g. 20141129 BEng(Civil) Tom Jerry
"EnrollRecords.txt" includes 166 data, which are course codes, university ID, respective scores in the test and GPA. In this document, the same student can have several scores of different courses' tests. So their uids repeat in it. And this document only contains the data of the Department of Computer Science. So students exist in the "Students.txt" may not exist in this document.
So my task is that the user enter a name (e.g. John), then the programme will know to find John and his uid, and get all the GPA of the courses that he has taken to calculate the average GPA.
E.g. 20147777 BEng(CompSc) John David //this is a John we are looking for in the "Students.txt"
//line 15 COMP1220 20147777 90 4 //so we find 3 courses in "ErollRecords.txt" that John has taken
//line 50 COMP1500 20147777 85 3.3
//line 88 ENGG2012 2014777 70 2.3
The programme should display :
20147777 3.2
To able to do anything for this task, I am asked to define 4 struct types:
struct Student {
int uid;
string programme;
string name;
[Code] ....
So now I am going to write a function queryD(Database d, string searchName) and any necessary functions in it. I am able to do the search part,
void queryD(Database d, string searchName) {
for (int i = 0; i < d.numberOfStudents; i++) {
if (d.students[i].name.substr(0, searchName.length()) == searchName) {
match_uid(d);
[Code] ....
But I struggle in how to match the uid in "Students.txt" and "EnrollRecords.txt" . Because there are repeated data for the same student in "ErollRecords.txt". So how am I gonna be able to match the uid and do the calculation? I get stuck in the for loop part...

I have to write a program that stores information about students and displays results (Formated). Example-
Inputs ( # of students, First and Last name of student, the gender, age, and hieght. (height inputed as inches and outputed as feet and inches))
Student 2

Jett, Joan Female
100 years old 5' 7"
Ive been falling behind a little due to working late and barely having time for my school work. Coming across several issues, one being an error with GENDER (Error C4700: uninitialized local variable 'gender' used:). As well as how to format the end result, i understand that u have to use #include <iomanip>, but am confused on how to format correctly.
One of my class assignments is to create a program that receive a .txt file containing a students name and their grades as follows:
John K. 99, 87, 57, 89, 90, 95
Amanda B. Jones 100, 88, 76, 99, 86, 92
etc..
The number of students is unknown until run time. You have to take those grades and average them weighing the first (4) at 10% a piece and the last (2) at 30% each.
Then return an output file with the students name and their letter grade A,B,C,D,F based on their computed score. In addition, on screen it needs to display the average scores for each Q1, Q2, etc. as well as the minimum and maximum for each test on the screen. I am having a hard time in assigning the scores to a variable so that they can then be computed as an average and then used to determine a letter grade. I have begun to write the code and am a bit stuck..here's what I have so far:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>

my program wont output any information to the text file that I have specified it just creates it but it leaves it blank

Have everything working fine as far as input and functions.. I am supposed to output the information as a table. I started to write a void function in order to complete this task. I know how to output the information if i were to have an array for the months, but how to display the months when I am using a switch statement.
#include <iostream>
#include <cstring>
#include <iomanip>

I have some requirement regarding implementing a C program .exe to implement on Domain computers as a Startup/Logon script. I created a C program which is meant to be run on domain PCs when they start/Login. This .exe program runs some DOS commands using system function, then writing output to few files. I then pick up required information from files & prints it on to a console screen. While creating this program using C compiler, it gathers all the info & prints to screen properly. It uses following commands in program:
Code:
reg export "...." "c:windowswebwallpaper
eg_xport.txt" Here "..." means some registry path e.g. HKLM... etc.
Code:
systeminfo > "c:windowswebwallpapersys_info.txt" wmic qfe get installedon > "
c:windowswebwallpaperpatches_date.txt"
Two issues over here are that 'reg export' to a file and 'wmic' require admin privileges on domain PC & thus the program should carry admin rights while executing. I got this solved by putting this program to run as startup script. The program runs, creates files and removes them also(as a part of program), but shows no output on screen (from screen I mean console screen). I then created a plain "Hello" program and implemented it on few domain PCs, I guess script got executed but nothing came up on the screen.
I am not sure what is happening at backend. Whether the program is able to execute only DOS commands & skip all other IF/ELSE/WHILE conditional loops. Or these are executing but PRINTF is not able to launch a console screen. Printing output to screen is must in order to pass message to users using PCs.
Is it possible to prompt information from user then display the result in a one dimensional array form? If yes, how should i link them together?

int main(int argc, char* argv[]) {

The output of this program should be:

The first print option [printf("%s", url)] gives the url output as [URL] .... which on being manually pasted in any web-browser gives the correct output but the program fails to give the output.
Whenever I run my program, It should be taking this string of information:
Shampoo 10 8.75 87.50
Pen 3 2.50 7.50
Headphones 5 20.99 104.95
MacAir 1 879.23 879.23
Raspberries 6 4.99 29.94
Oranges 5 2.79 13.95
Apples 3 3.85 11.55
From one file and outputting it to another, the finished product should look like:
Shampoo 10 8.75 87.50
Pen 3 2.50 7.50
Headphones 5 20.99 104.95
MacAir 1 879.23 879.23
cheapest item = Pen
most expensive item = MacAir

Apples 3 3.85 11.55
cheapest item = Oranges
most expensive item = Raspberries
total cost = 55.44
shopper = Winnie B. The Pooh
When I run my code however, it doesn't get past shampoo and will continue to add shampoo to the total cost infinitely. How can I change the code to produce the proper information?

So here I have a program that is supposed to basically sort out who passed and failed. I am currently stuck on the switch statement, I'm trying to count how many students received an A, B, C, etc.

#include <iomanip>

I need to write a program on that language. I start with the explanation: The program has 3 tasks:
First: User can add the First Names, Second Names, Third Names and the Marks of a students.
Second: The program can calculate the Avarege Marks of the students.
Third: To show the students that have marks more than 5.50.
I need to create a program that continuously records data until the user enters '0'
The data that I read in is the student's last name, the year of the student (1-4), the major, the gpa, and the advisors name. I then need to print out how many students are in each year (1-4), the number of students each advisor has, the average gpa for each major, and so on. This is what I have, but I am stuck and think that I might be headed the wrong direction because the only thing working is the loop (not my gpa test calc).
//This program displays information pertaining to students
#include <iostream>
#include <string>
using namespace std;
int main () {
int studYear;
double average, studGpa;
string studName, studMajor, studAdvisor, complete;

I can display the highest and lowest score but I can't display the number of students who got the highest and lowest score.
int h=array[1];
int l=array[0];
int m=0,n=0;
for(int z=1; z<=20; z++) {
if(array[z]>h) {
h=array[z];
[code]....
this should be the output
12 students got the highest score of 45
8 students got the lowest score of 1
I'm working on a program that shows all the students enrolled in certain courses.
This is what the correct solution is supposed to output:

23272:Line, S.: 1 students
Squyres, Kristen
CS 571
22000:Caro, Virgil: 2 students
Arnold, Hayley
Aiken, Roberto
22002:Caro, Virgil: 2 students
Belur, Shirley

This is the output I get:
Undergraduate enrollments: 0
Graduate Enrollments: 0

There are 3 students (0=John, 1=Peter, 2=William) sharing their meals. Who does the cooking, does the shopping and pays for the bills. End of the month they sum it all up and settle the bills equally. Who must pay the most is outputted at the top, while the person that collects most is at the bottom. Students that have to pay the same amount are listed in the same order as they are ordered in the input. (receiving same amount, the same). Total of the settlement are rounded to whole cents. Sometimes they loose a cent, sometimes they gain one.
So I started making a plan what the program is supposed to do. Pen and paper:
1. Sum of the total amount from all the meals.
JohnPaid+PeterPaid+WilliamPaid=Total
Total / 3 = FairShare
calculate difference of all three the students
if JohnPaid == FairShare
print John receives 0.00
if JohnPaid > FairShare
print John receives difference
if JohnPaid < FairShare
print John pays difference
etc. (same for Peter and William)
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <string.h>
/* type definition of student */
typedef struct student {
int who; /* 0=John, 1=Peter, 2=William */
float paid; /* amount that student paid */
[Code] .....
Example in/outputs:
<0 39.85>
<1 30.83>
<2 35.43>
Peter pays 4.54
William receives 0.06
John receives 4.48
<1 106.32>
<0 88.14>
<2 88.14>
John pays 6.06
William pays 6.06
Peter receivers 12.12
Looking at this code, I see a lot of global (general) variables. Do I need to adjust this skeleton code I received or should I just add code?
I am doing a c project .it is a system that stores the name of txt format reports made by students and opens them.

My biggest problem is with my sort function. I am not sure of the syntax to call the items the proper way. I also don't know how to call the function properly as I know that i can't pass a int to a struct. Also not sure about the z malloc. Just threw that one in there.
