C++ :: How To Add A Loop / User-defined Function And Array / Structure To Code

Apr 24, 2012

We had to write a "selling program for computers, laptops and tablets", which I did but for the extra credit, we have to have those three points in the application and I have tried but how to do the "extra credit" part, which I really need.

1.) A loop to prompt the user if they would like to place another order

2.) At least one user-defined function

3.) An enumerated data type, array or struct (structure)

I did one of these three, it's a "DO WHILE" loop asking users if they want to make another order, it's right at the beginning of the code.

Code:

#include <iostream>
#include <string>
#include <iomanip>
#include <fstream>
using namespace std;
double desktop();//function prototype
double laptop();
double tablet();

C :: Linear Search Script - Calling Array Inside Of User Defined Function?

Jul 24, 2013

im tasked with creating a linear search script using functions on a 10 element array. the elements are to be supplied by the user as is the search target.

I understand how to create the array and gather that information from the user as well as howto set a variable for "target", this is what im calling it. Those two parts are simple enough.

I am not fully understanding the calling of an array in a function as a pointer. i semi understand the use of a pointer and howto call a normal pointer in a function. i also understand that an array is nothing more then a "special" pointer with a set of consecutive address blocks for the size of the array.

My first user defined function is simple enough

Code:
ReadArray(int A[], int size){
int i;
printf("Please enter %d integer numbers separated by spaces:
", size);
for (i = 0; i < size; i++)
scanf("%d", &A[i]);
}

Sso nothing out of the ordinary there. that should be a standard for loop and use of scanf, sadly prof has not covered ssanf or any of the other options so i am stuck using scanf for now. maybe someday down the line in a other program or after this course ill get the chance to learn about better options for gathering data from the user.

I am confused as to my next function:

Code:
void SearchArray(int A[], int target, int size);

I've not written any code here yet as im not sure if i should call the A[], or *A for the first type of the function?

If i call *A do i then use something like this for my search:

Code:
for (*A = 0; *A < size; *A++)
if (*A < target) or use A[] insteadA?

Code:
for (i = 0; i < size; i++)
if (A[i] = target)

C :: User Defined Array Size

Jul 23, 2014

The instructions call for the user to define the size of the array and all I have ever done is use a predefined size for the array and then let the user fill it. Here is what I have so far:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
void Display (void);
void random (int *, int);
void Ascending (int *, int);
void Descending (int *, int);

C++ :: User Defined Function - String Related Program (swapping)

Jan 4, 2015

Write a program using user-defined function which is passed a string and that function should cycle the string.(Do not use any string related functions). E.g.

If the string is : Chetna then it should print as Chetna, hetnaC, etnaCh, tnaChe,naChet, aChetn

Ans.

#include <iostream>
using namespace std;
char swamp(char a[], int x) {
for(int k=0; k<=x; k++) {
char l= a[x]; a[x]= a[0]; char p=a[x-1]; a[x-1]=l;
for(int i=1; i<x-2; i++) {

C++ :: How To Assign Char Array As User Defined String Object

Apr 17, 2014

STRING s1 = “FOOBAR”

Here STRING is a user defined class. how to assign a constant char array "FOOBAR" to string object? Copy constructor need to be same class type as parameter. and overloading assignment operator also need to be same class type. I think 'friend' can let pass another type of object rather than STRING to do operation on overloaded '=' operator. How could it be done if it is possible at all?

C/C++ :: Create User Defined Dynamic Array For Player Scores - Missing Pointer Types Error

Jan 18, 2015

I'm completely new to pointers and have a homework assignment due where I'm supposed to create a user defined dynamic array for player scores. The only errors I'm experiencing is a C2109: subscript requires pointer type and only on the lines that use the int *score; variable (57, 62, 64, 69, 71, and 82). I've already tried adding = nullptr to the variable and that didn't work.

#include<iostream>
#include<string>

using namespace std;
void players(string[], int[], int);
void average(int[], int);

C++ :: STL Set Orderinf User Defined Objects

Mar 4, 2014

#include<iostream>
using namespace std;
#include<set>

class person{
int age;

[Code] ....

When I executed the above code it displays

Age is 37
Age is 25

Here I have defined operator< so that set can identify the order of person objects. I am clueless how set could identify that

person p[3]={person(25),person(37),person(25)};

I have provided one duplicated object with age 25

I havent overloaded == operator also,then how it could identify?

I am writing some code to bubble sort a list of randoms numbers, 10 at the moment. I want to be able to user input the amount of elements that would be sorted. I think i'd have to use vector instead of arrays, but unsure how to do this. Or, how to be able to change the size of the array.

C# :: For Loops To Make User Defined V Shape Output

Jul 29, 2014

Write a program to ask a user to input a symbol from the keyboard and to output that symbol in a n X n/2 sized V where n = the width of the V. You must use a loop to process the data

I am stuck at trying to figure out how to do the actual output formatting. This is where I am sitting currently.

string character = "";
int vheight = 0;
Console.WriteLine("Enter the character you wish to use for your V: ");

[Code]....

so Im really just a bit stumped on how to get the actual V shape to be formatted..

C++ :: Sorting Strings / Arrays In A User Defined Lexical Order?

I previously tried to put strings in an array, but i couldn't modify the first index in the string that is in the array. I changed my code later.

Suggest a function that sorts the inputs vertically according to the order given by the user? I made this one

void order(string order, char index[][15]){
int counter=0,line=0,i=0,j=0;
for(i=0;i<=15-1;i++)
{for(j=0;j<=15-1;j++) {

How to structure something like Game Menu. I was googling and did not find anything useful. I am coding a little game and Menu part with few sections like START GAME - SELECT LEVEL - SETTINGS (SOUND, MUSIC AND VIBRATION ON/OF) - CREDITS - EXIT.

And just menu alone seems to have tones of code. I have my state machine working but it seems every subsection of the menu has its own state sort if and duplicate code.
