I have a program where the user inputs a line of integers, and then all unique ones are outputted. It works fine-almost. It prints the numbers correctly, but prints them more than once and I'm not sure why.
Code: #include <iostream>
using namespace std;
int main ( ) {

I have a program that makes change from an amount. It works fine, but the output is the correct output looped over and over. I have tried everything, but it still doesn't work. For example, a amount of 98 should print
3 quarters
2 dimes
0 nickles
3 pennies
but instead it prints
3 quarters
2 dimes
0 nickels
3 pennies
0 quarters
2 dimes
0 nickels
3 pennies
0 quarters
2 dimes
0 nickels
3 pennies
Why it's doing this?
Code:
#include <iostream>
using namespace std;
int coinscount(int& amount, int value) {
int tracker = 0;
int amountdimes = amount;

I need to make a program that prints certain pictures. My program compiles successfully. However, I cannot figure out how to view the ppm output. When i run the program i get a lot of random text.

It seems that it's just missing a space (and therefore a setw and setfill), but I found 2 problems:
1. The space needs to not apply to the first line.
2. I can't get it to make a space before each row without making a space between each column.
My current code is:
#include <iostream>
#include <iomanip>
using namespace std;
int main ( ) {
int rows;
[Code] ....
I have tried putting in << setws and << setfills of various values but it seems to always apply to between each column as well as at the start of each row- what do I do?
I have a program that prints out pascal's triangle. One problem: it isn't a triangle. The output doesn't work. This is what it should print:
Code: How many rows: 4
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1 and this is what it does print: Code: Enter a number of rows: 4
1
1 1
1 2 1
1 3 3 1

So I need to make a program that reads distance and number of days of a person that is buying a ticket. If distance is greater than 1,000 kilometers AND the person stays more than 7 days, the discount is 30% of the ticket. The cost per kilometer is $1300. Print the ticket with discount.
I used variable distance as float because it will be multiplied with 0.3 for the discount... not sure if I'm right on that.
Code:
#include <iostream>
#include <conio.h>
using namespace std;
int main() {
float distance;
int days;
[Code] .....
I tried another way but haven't done it in code...
ask for distance
ask for days
Ticket= (Dist x 2 x $1300)
If (dist>1000) && (days>7)
cout<<Ticket=Ticket * 0.3;
else { cout<<Ticket;
#include <iostream>
using namespace std;
int main()
{
int num = 2;
int count = 0;
while (num <= 100)

How to do that. It's rare that I post without figuring anything out, but I'm just simply not sure. I have a program that prints a triangle in a similar direction, so maybe if I could get some hints as to what to do with that (HINTS, not direct source code) .

I am working on an assignment to enter a number and print all the prime factors of that number. I have that working, but the assignment demands the output be formatted in a strange way which I can't figure out. For example, in my current program entering 10 gets me 25, which is actually 2 and 5. But it should get me: ( 2 * 5 ) but I can't figure out how to do this. On the chance you need it, my code is below:
Code:
#include <iostream>
using namespace std;
int main( )
{
cout << "Number: ";

Write a program that prints a multiplication table using nested loops. In main ask the user for the smallest column number , the largest column number and the size of the increment. Ask the user for the same information for the row values.
In the example the column values entered are: 5, 15 and 2 and the row values 3, 6 and 1.
Given those numbers you would generate the following table.
Multiplication Table
| 5 7 9 11 13 15 ___|___________________________________ | 3 |
15 21 27 33 39 45 4 | 20 28 36 44 52 60 5 | 25 35 45 55 65 75 6 | 30 42 54 66 78 90
Print the 24 values with the grey background. The other numbers show the values to be multiplied.
Code:
#include<stdio.h>
main() {
int a,b,c,d,e,f;
int i,j,total;
printf("Please enter smallest column number: ");
scanf("%i",&a);
printf("

I'm trying to create a program that prints a number of dots specified by the user, there 4 options to do any loop type or to exit the menu. i'm having problems making it so that after you enter a value and it displays the specified number of dots it clears the results. Also we have to make it so that if a negative integer is entered it still prints out the appropriate amount of dots ie: user puts -9 it prints 9 dots, i know you use the abs() function but it doesn't seem to be working for me. I'm assuming my problem with the abs function is i'm not using it correctly. Use case 1 as the example for the rest because I'm trying to implement everything on one case at a time

int main() {

the question is; Write a program that prints out the memory addresses of each element in a two-dimensional array. Check to see if the values printed out make sense to you based on the way I explained it before.
Below is the code I have done. I am having problems printing the "-" sign to keep formatting with the board when the user enter in different dimensions other than [4][4].
Code:
#include <iostream>

for (int i = 0; i < y; i++) {
p_p_twoDimension[i] = new int [x];}

I need to create a program that prints a certain number of asterisks based on user input. The user inputs 5 and I want my program to output "*****". How would I do this in C? I've tried printf("%#**", myvariable) but this does not work it only prints "*".
View 1 Replies View RelatedI would like to understand a function on strings. Below is a code that I took from my teacher where the user inputs a string and prints out the length of the string.
Code:

#include <string.h>
int main() {
char str[100];
int i = 0;

Now I understand that it returns the count in "int" so my question is:
Let's say i declared
Code: int count = 0;
at the beginning of the code and then made
Code: count = strlen(str);
why wouldn't i have the same result? Is there a way to do it also?
I need to make a program that prints out 10 random questions from the 15 questions in a .txt file, and then print out the choice IN RANDOM.

It only prints: The value of count is 1. I'm confused on why it doesnt print the value of the count is 5
So i have this -

iElapsedYah = not zero and iNumTimes = not zero

Im trying to make a Tic Tac Toe board for an assignment. Right now it compiles fine but when I enter an x or o it does not update the board it just prints out the '.'s that the board is initialized to. Also, when I get to player 2 the board will printout twice so its 6 rows or 3 columns. The project uses a main to ask who starts then goes to a play function that asks for inputs and calls the makeMove function to place the x's and o's and the print function to display the updated board.
bool Board::makeMove(int rowIn, int columnIn, char currentPlayer) {
if (playBoard[rowIn][columnIn] == '.') {
playBoard[rowIn][columnIn] = currentPlayer;
return true;

I know for while loops you type
while(argument){
do whatever
}
you have to use the brackets to enclose just like I used in my code right here.It is a simple while loop that is a countdown.
#include <iostream>
using namespace std;
int main() {
int n =10;
while(n>0){
cout << n << ", ";
[code].....
when I take the brackets away from my while loop, my code will still execute but it just prints out the number "10" repeatedly. I was just wondering why it does this and why the compiler does not throw out an error when I leave off the brackets after the "while()".
#include <stdio.h>

int num;
