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...

Student 2

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.
Write a program that a prof can use to enter the test marks of several students and which calculates the average mark of each student. Ask the user how many students he has, then ask him to enter each student's marks. When 999 is entered, calculate the average mark for that student (not counting the 999) and print the average. Then go on to the next students until the marks for all students have been entered, calculated and the average printed.
Code:
#include<stdio.h>
main() {
float student,mark,total=0;
float a,b,c;
int num = 999;

Program that reads 10 students marks and display the average, the maximum and the minimum marks.

In this program i am able to get Average Marks and Minimum Marks But i am not able to get the Maximum Marks Output correct.
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:
132475.889.392.3
435686.383.498.3
479090.177.376.9
839373.976.389.3
556397.378.478.9
832987.365.377.2
271767.989.379.3
ReadData will have one argument, the scoresArray.
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.
Student #Test1Test2Test3Average
132475.889.392.385.8
etc, etc
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.

When I run the following just to see where I am getting I get the following error:

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?
I am writing a class that dynamically allocates an array that holds a user-defined number of test scores (test scores go from 0 to 10 both included). Once all the test scores are entered and validated (values only between 0 and 10, both included), the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates theaverage of all the scores.The main program should display the sorted list of scores and the average of the scores with appropriate headings.

View 2 Replies View RelatedI 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:
Normalized x= (x-min(array))/(max(array)-min(array))
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;

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 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.
the value of C(k,n) are known as the binomial coeficient and can be arranged in triangle that was known as pascal triangle.
i was been asked to create a program that can display rows up to n=9 using print array function.
C(k,n) = C(k-1,n-1) + C(k,n-1)
how should i start?
