3. Can i change the process-name when the programm started?
4. Can i save my .exe under another name in the autorun
I'm new to C++ programming and only have a little java experience but I'm trying to learn some C++. I want to create a simple contour plot from scratch, and I see that there are many programs online, but what I haven't found are the basic components to a contour plot! I know that I have to make some kind of grid, I need to identify/set levels, etc.

I have a program that I can only run one instance of. When I try to start it a second time, it doesn't do anything. I would like to create a script that loads the program in a way that I can run multiple instances. Since I assume the program checks the process tree on startup to see if an other instance is already running, I figure disabling access to the process tree could do the trick.

What I have: A basic program for infinitely looping after and testing for an active process. It has a delay system built in to make it so it is not constantly iterating.
What I need: A way to get process IDs from other Processes other than my program. With a way to use that ID to detect if that process is active on the computer or not.
Parts of my code that need changing:
/* Code for handling the process would go here */
/* Code for detecting the target would go here */
What the goal of my program is: Perform operations to terminate the process of cmd.exe when it is active on the user's computer. Then output the status of the process and the time it took to find that process to the user.
It contained functions that I needed, but I need more information on how to apply them to other processes instead of the parent of my program and its' children.
Here is the code I prewrote for this so far:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define ZERO 0
#define INFINITE 1000000000000000

Can i later change the name of the ch variable to lets say "number" the code now becomes

I have a current assignment for C++ involving us to make a program to determine coin change for example if you input the number 127 you would need 2 half dollars 1quarter and 2 pennies I have no way how to program this.
This is my code that doesn't do what i want it to
#include <iostream>
using namespace std;
int main ( ) {
float change;
int half_dollars, quarters, dimes, nickels, pennies; // declare variables

How do i change color of text in the program more than once . rite now i use the code
system ("color 0c");//makes the color of the text red
cout <<"hey";
system ("color 02") //change color to green;
cout<<"only in green ";
it displays both the lines in green not the first in red and second in green.
the problem and my code is at the bottom, the thing is when i checked out what my change was, it was it was like -14.23 which is werid.
Write a program that determines the change that the user should receive after having paid for their purchase. Your program
prompts the user for the number of items purchased
accepts the number of items purchased
prompts the user for the unit price of each item
accepts the unit price of each item
calculates the total purchase price, including HST
outputs the total purchase price
prompts the user for the cash tendered
accepts the amount of cash tendered
calculates the change owed to the user
outputs the number of loonies in the change
outputs the number of cents in the change
You may assume that the user enters valid amounts and tenders enough cash to cover the total purchase price.
The output from your program looks something like:
Enter the number of items : 4
Enter the unit price : 3.15
Purchase price 12.60
HST (13%) 1.64
Total price 14.24
Cash tendered 20.00
Change loonies 5
Change cents 76

Alright so I'm in a computer programming class and I was given the following problem..Write a problem that takes an integer value and multiplies each of the digits together. 4 digit numbers only.
IE; What number do you want to process? 2684
Starting number 2684
End result 384
I know how to start the begging of the program, but i dont understand how to have it to where you can type in all four digits and then it will multiply each number by the other. Also, what are some ways to change the color scheme of the program? I know how it works using CMD, but in Visual C++ its totally different aha.
And for some reason my program pauses (nothing displays, and my cursor changes to the little "loading" cursor thingy) when it hits line 139. That is where I added an additional piece of code that should change the shape of the triangle while the program is running.

#include <WindowsX.h>

My coin/money change code works when there can be an exact change each time, i.e. when the 1 cent option is available. However, when the change options are only $10, $5, $1, 25 cents and 10 cents, it does not give me what I want for instance, I wanted to get change for $237.80, I was expecting to get:
23 10's, one 5, two 1's and 8 dimes. However, the code below is giving me 23 10's, one 5, two 1's and 3 quarters (there is no option left for the 5 remaining cents).how to fix it?
Code:
#include<iostream>
#include<algorithm>
#include<vector>
using namespace std;
void change(double cents, int a[]);
int main() {
double Dollars;
double cents;
[code]...
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 have app that has while true on input listening to changes and then in some condition needs to open simple gtk app, and afterwards continue listening.
I thought that i could fork gtk part, and kill it when it is not needed.
But am not finding much examples on internet. 2 processes dont share data. Can child process start a gui app? And is this a good approach.

i have read that inheritance slows down the process.because a_class -> b_class -> c_class it goes thorough many classes to find a function or a value. people advices not to do it more than a few times. what if instead of inheritance we are using headers, would it slow down the process also??i mean which one is faster? and arent both the same when we use headers or used inheritance.

how I can run this as a separate process from the parent program, like a child process,
and return the result back to the parent program.
this script is as follows.
if file "/Stuff/s" exists then continue to run, if file "/Stuff/t" exists, then print "started" if file "/Stuff/t" does not exists, then print "stopped"
if file "/Stuff/s" does not exist then print "quit" and then quit.
Code:
void controlxmmscheck( ) {
if( access( "/Stuff/s", F_OK ) != -1 ) {

tell me which .dll or library I'm supposed to use to link this program:
#include <iostream>
using namespace std;
void antpost (int num, int& anterior, int& posterior) {
anterior = num-1;
posterior = num+1;

I think my linker needs an additional #include to be able to deal with int& anterior and int& posterior. I'm not sure as I'm new to C++. My version of Dev-C++ is Orwell V5.8.3.
