I tired changing the conditions in the for loops, but then I end up entering information multiple times and I want that to be the user's option. Do I have to change the for loops or something else? I've tried everything to get what I want but nothing works. When I print the receipt, only the last food Item that I entered prints.
Using a for loop, construct two 100 element arrays, x and y, such that element i of x stores the value sin(2*pi*i/100)) and the corresponding element of y stores cos((2*pi*i/100)). Print the values stored in the elements of x and y as you calculate them.
I have attempted to solve it but I'm not sure why the value 0 is only being printed, maybe I haven't assigned sin(2i/100)) and cos((2i/100)) to the arrays properly?
Code:
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
int main () {

I wanted to sort two structure-arrays according to their element values and get their indices changed accordingly.For example if my array is
A[]= { 2 4 1 8 6}
indices[]={ 1 2 3 4 5}
then after sorting it should become
A[]= { 1 2 4 6 8}
indices[]={ 3 1 2 5 4}
I tried implementing it using the following code but I failed to get correct output.
Code:
#include<iostream>
#include<cstdio>
using namespace std;
#define inf 100000
struct array
{
int x;
int y;
};

We are supposed to create a menu with an option to add a car (make, model etc) to inventory. I have the structure format set up as far as adding the car, but I am stuck on how to make it a dynamic array of structures or whatnot (I'm not really sure on what I'm trying to do in the first place!) Basically, the user can choose to add a car and its info in. How do you set up the array to add whatever number of cars is needed? Will it be able to add more cars should the user come back to the program later?
This is the instruction of this portion of the project :
Menu Application
Add a car to inventory
Prompted to add
Make, Model and Year, Color, Miles, Price
Finish (adds the car to the file)
Cancel takes you to the main menu
Write a program that uses a record structure to store a Student Name, Student ID, Test Scores, Average Test Score, and Grade. The program should keep a list of test scores for a group of 6 students. The program should ask for the name, ID, and four test scores for each student. Then the average test score should be calculated and stored. The course grade should be based on the following scale:
Average Test Score Course Grade
------------------ ------------
90 - 100 A
80 - 89 B
70 - 79 C
60 - 69 D
59 or below F
A table should be displayed on the screen listing each student's name, ID, average test score, and course grade. Implement with functions.
My code runs but it isnt returning anything (readable/correct) and i have no clue why. This is what i have so far:

using namespace std;
const int columns = 4;
struct StuRec //user defined datatype {
int id[6];
char names[6][20];

Any example code for printing a square matrix without arrays?
View 7 Replies View RelatedI'm working with arrays and I get them column by column and need to print them. I as there a way to print in columns?
For example: I produce an array of A, B and C from a loop and then need to print them in one column and the go to the next column ....
so in the end I shall have an output like this:
A E
B F
C G
D h

My arrays are too long (over 50K) so I cant just store the arrays and then print them. I need to produce each column array, print them and delete it and go to the next column.

6 7 -9
Code:
size = 50; //they dont all 50, its just that array cant be bigger than 50

i got 2 arrays, how would i print 10 numbers per line, so that would be 5 numbers from each array.
array1[40];
array2[40];
array1 array2// array1 array2// array1 array2 // array1 array2 // array1 array2
array1 array2// array1 array2// array1 array2 // array1 array2 // array1 array2

how can i put this in a loop?
and so on but there are 80 elements so i cant go one by one.
I have a problem in dealing with dynamic arrays. I have initialized the objects and now i want to print them.

The print function does not work. I have to implement the print function without taking any parameters.. How should i do that ?
I define "Comwords" as a string, but apparently it takes the members as chars, then I can't set strings in a structure equal to the chars.
I see to also be having unknown problems with the ComMAL array and loading it values into another element of the same structure.
How to correct this? I was thinking of casting char elements as strings, but could find no reference in my library book regarding how to do that (lots on casting int's a doubles...)

Ok, for my Sunday homework I have to find the next day of the year using structures. Now, I can get the structure to read the entered date (tested that with a simple scanf to printf entered data), but I need to get it to be able to tell that it is the end of the month and print out the next month when necessary. Here is what I got so far:
Code:
//Cameron Taylor
#include <stdio.h>
struct Date{
int month;
int day;
int year;
[Code] ....
As you can see, I am trying to use an array for the max day of each month (excluding Leap Year for now).
Where I use the entered month to = 'i'. Then I use 'i' as the position in the array to see if next.day is = to the max day of that position of the array.
I am having no compiler issues with GCC using -w or -Wall, but after entering the current day the program stops working and doesn't go beyond the input.
commiedic@localhost Project18$ gcc -o -Wall Exercise4.c
commiedic@localhost Project18$ gcc -o -w Exercise4.c
commiedic@localhost Project18$ gcc -w Exercise4.c
commiedic@localhost Project18$ make Exercise4
make: `Exercise4' is up to date.

I have to do a project for Programming and he said in quotes
"Programming exercise 10.6: the programming project is as described, except do not represent the points using structures.
Assume, as known, the ten (x,y)-values corresponding to x=0.0, 0.1, 0.3, 0.45 ..etc and use y-values from the
function xsin(x); as in (x,y)=(x, xsin(x)) = (0.3, 0.3sin(0.3)).
Use value n+1=10, so the LaGrange polynomial will be order = 9."
What does it mean to not represent the points using structures??
int arr[4][5];
for (int(&row)[5] : arr){
for (int &column : row){
} }
Why do we name it row instead column?
int arr[row][column]
Wouldn't this be like
int arr[4][5];
for (int(&column)[5] : arr){
for (int &row: column){
}
It just seems funny to me because we use row[5] which should be 4 if we meant row? Or did I read it wrong in C++ prime !?

I am going to be using a boolean variable to mark whether or not a specific field has had data entered into it. I figure the best way to do that is to initialize all the elements of the structures to 0. However, with strings and with the nested structure, I'm not sure how to do this.
is possible to combine structures declaration and definition in programming language?
