C++ :: Struct Output Using A Loop?

trying to output my struct to a for loop. I understand how to output the struct but not into a for loop.

#include "stdafx.h"
#include <string>
#include <iostream>

struct Date {
int day;
int month;

C :: Creating Simple Address Book Struct - For Loop?

May 11, 2014

My address book will be simple, and the thing's that I'm expecting to use in it are :

Pointers, Linked Lists
Malloc
Structs
Typedefs
Makefile, header file
Putting functions into different program files

I have started the program trying to create a struct, and getting it working with a couple of entries before going onto user input and splitting it up.

Code:

#include <stdio.h>
#include <stdlib.h>
int main(void) {
// Struct type address book. Just a name, a number and a pointer

[Code] .....

I'm a bit lost at this point... My knee jerk thought is to create a for loop, and cycle through the list.

I'm not sure how this would apply to this though? Without using the familiar type of print loop such as :

Code:
for (i = 0; ;i++) {
printf("%i
", array[i];
}

I'm thinking that I need to create a temporary struct that can be used to assign the value of the next struct in the list, and then somehow print from that....

I'll try and write the logic out :

while temp != NULL (The last node value is assigned NULL to show us where the end of the list is)

create a temporary pointer that can be used to keep track of where we are in the list.

print out the current entry name and number

then assign the temp pointer value to the * next of the current struct. So if we are in entry1 the *next should be the address of entry 2.

Print out entry 2 name and number, assign entry 2 next to the temp value.

C++ :: While Loop Stops Output

Jun 19, 2014

As I was testing it, the program suddenly stopped giving an output. Here is the code:

#include <iostream>
using namespace std;

int main() {
cout << "Ten people ate breakfast with you this morning. Each of them " <<
"had pancakes.
Please enter how many pancakes each of the ten people " <<
"ate.
" << endl;

[Code] ...

The while loop after int glutton does not work and seems to stop the program. I replaced the "glutton" in the cout with "testing testing" and it still did not work. However, when I commented out the loop, it appeared. Finally, it can't be what's inside the loop, because I commented that out too, and it still didn't work.

C/C++ :: For Loop Not Producing Correct Output

Nov 14, 2014

Something is wrong with option 1. For some reason it adds 1, 2, 3, 4 ... 5 onto the output and I can't think why. Here is a screenshot.

Also how can I make the output a little neater? I tried to use but it just looks horrible.

I had linked the source code! Why is there no edit button?!

#include<iostream>

int main(){
int option;
cout << "Welcome to my program. Please select a following option.

C++ :: Writing Output Of While Loop To Text File?

Jul 30, 2014

[URL] when I try to write my output to a file. I am building a life insurance premium calculator with c++. What my calculator does is read in a text file called "policies.txt" containing a number of different policies. For example:

Pol1 M N 20 100000 1 .04 99
Pol2 F S 30 100000 1 .05 99
Pol3 M S 72 750000 1 .03 99
Pol4 F N 45 1000000 1 .05 99

And using this, it creates a single premium. Once the calculator calculates the premium of each policy, I want it to write out the premium amount of each policy to a textfile called "output.txt". The problem is that when I check my "output.txt" file, only the premium for the last policy shows up. It only reads:

Premium for Pol4 is 220384
When I want it to read:

Premium for Pol1 is 14101.6
Premium for Pol2 is 14221.2
Premium for Pol3 is 582391
Premium for Pol4 is 220384

How come only the last policy is showing up? and is there any way to make all four policies appear in my output text file? Here is my code:

double ratesmn[86] = {
#include "MaleNonSmoker.txt"
- 1
};

C++ :: Displaying Correct Output By Using For Loop (with Pointers)

I wanted to display the correct output by using a for loop at the end of my code, but for some reason it's not working correctly.

using namespace std;
int main() {
int* ipArray[3];
for(int i = 0; i < 3; i++) {
ipArray[i] = new int [5];

What I wanted to do is pretty much match my 1st out put like 0 1 2 3 4 but my 2nd output only outputs 24's and I don't know why

C/C++ :: Loop Indentation - Output With No Extra Whitespaces

The expected output has no extra whitespaces, but mine does. What am I doing wrong?

C/C++ :: Sizeof (struct) Returns 6 More Bytes Than Actual Struct Size?

Sep 14, 2014

#include <stdio.h>
#define MAX_USERS 20
struct {
char ID[10];
char Name[40];
int Pos;

[Code] .....

I was attempting something weired with address to move data around when I discovered that the size of the array is not what I expected. I am passing this structure as &Users to a function that declares it as a void *, then I can deal with chunks of data (memmove) and not have to worry about index or things like that. However...sizeof is returning something I do not understand.

These codes give these errors:

error: request for member 'character' in '* ptr', which is of non-class type 'datastructure*'

These errors are related to

C/C++ :: How To Change For Loop Into Do While Loop

Apr 19, 2014

I already made a nested for loop into a while loop (below this) and now I'm trying to make the outer for loop into a do while loop, but it's not working.

#include <iostream>
using namespace std;
int main () {
int len;
int j;
int i;

[Code]....

And I can't make this code do the same thing. It stops after one loop, instead of continuing to the end. Why won't the loops continue?

#include <iostream>
using namespace std;
int main(){
int len;
cout << "Enter a number: ";

C/C++ :: Convert A While Loop To A For Loop?

Mar 25, 2012

I need to convert the following while loop:

count = 1;
while (caloriesForItem != 0, count != numberOfItems )
{
cout<<"Enter the calories: ";
cin >> caloriesForItem;
totalCalories += caloriesForItem;
count++;
}

This is what I have come up with:

totalCalories += caloriesForItem;
for (count = 1; caloriesForItem != 0; count != numberOfItems)
{
cout<<"Enter the calories: ";
cin >> caloriesForItem;
count++;
cout << "Total calories eaten today = " << totalCalories << endl;
}

However the output is not the same?
