C/C++ :: Program To Store Info About Students And Then Display To Screen
Oct 7, 2014
NOTES AT BOTTOM---EXPLANTION, PROBLEMS ETC. SCROLL DOWN
#include <iostream>
#include <iomanip>
#include <string>
[Code]....
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.

Q.1 Write a program to store marks obtained by 50 students. Initialise the array having passed to a function initilise() having passed the array as parameter. Write another function which should take this array as parameter and return the highest score from the array. you have to write the proper function call, prototype and definition for each function.
And this is the program which i wrote and got errors: -
#include<iostream.h>
#include<conio.h>
#define s 50
void init(int m[s]);
void display(int m[s]);
void find_max(int max, int m[s]);
void main(){
clrscr();
int max;

i need to display the current time and date in my program and use variable to store each of the time values like
a = 10
b = 29
c = 31
printf(``%d : %d : %d``, a,b,c);
which then give the output as - 10:29:31

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...

So I have an array of my own class, "Restaurant," but I'm having a hard time figuring out how to store the info entered by the user into the array.
In total, I have two classes. I will show you all I have, it's a lot but I know it will be easier to understand.
My problem is in the AddRestaurant(), since that is where I should ask the user for all the information and store it in the array.
Also consider that I have to use the FTime class as well to handle the time. Basically I want to do something like this:
info[count].SetRating();
which will put the rating part of the class Restaurant into the array[count]
Also, my program doesn't compile because of the AddRestaurant and PrintAll functions since what I am showing is what I want to do, not what works.
//main.cpp
#include <iostream>
#include <iomanip>
#include <string>
#include "Restaurant.h"
#include "FTime.h"
int ReadMenuChoice();
[Code] .....

I'm trying to make a program that you input your login info and it writes that info to a text file. Then, later on once I get my problem fixed, the program will read the info to the user. my code is as follows(the input part is a bit lengthy):
// Password Log
#include <iostream.h>
#include <fstream.h>
#include <string>
#include <time.h>
using namespace std;
ofstream login;
[Code] ....
What my problem is when I choose "Input new login info" it automatically inputs I have no clue, and calls next program.

I am using C++ new/delete operators to allocate/deallocate the buffers. I think for each allocated buffer, there should be an additional info block stores the size and other info about the buffer. How to know more details about this info block? I need to override these two operators and find such an info block is useful to my implementation.

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:
enrollmentReport.exe sections0.dat enrollment0.dat
Undergraduate enrollments: 1
Graduate Enrollments: 3
CS 355
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
Aiken, Roberto
This is the output I get:
Undergraduate enrollments: 0
Graduate Enrollments: 0
CS 355
CS 571
I've included all the source code in an attachment. The trick is that I can only modify the section.h and section.cpp
course.zip (523.39K)

I'm coding a hangman game. I'm trying to store user entries so i can output them to show the user what they have already entered. Problem is that it's not display anything at all.
I'm trying to store multiple characters of course, and then display all characters stored.
char guess[27]={0};
cin >> guess[26];
int hit=0;
for(int i=0; i<len; i++) {
if( guess[26] == hidden_word[i] ) {
hit++;
select_word[i] = guess[26];
if(strcmp(hidden_word,select_word) == 0) {
[code]....
EDIT: I also get the error - Stack around the variable 'guess' was corrupted. At the end of the game.

I have been asked to create a program that accesses an inventory file done in excel, look for a alpha-numeric code, which will be inputed by the user, and return to the user informations related to the position of that code, and informations related to the header of the column in which the code resides.
An example of the function I need the program to perform would be:
User inputs: 1429-R1
And the program returns: Marco's 6A, 8/21/2014, 3/7/2014.
using the following example of file:
Marco's 6A
Assessment 8/21/14 3/7/14
1584-R1 1584-R1 1584-R1
1461-2R1 1461-2R1 1461-2R1
1429-R1 1429-R1 1429-R1
