I'm trying to create a program that will show what the 12th digit of a UPC code would be. However, once the user enters the first 11 digits the program doesn't execute the last call of printf. The program compiles with no issues.
Code:
#include<stdio.h>
int main() {
int o1, e2, o3, e4, o5, e6, o7, e8, o9, e10, o11, oddsum, evensum, twelve;
printf

I'm working on a project that's got a lot of moving parts, from feedback from a position sensor to real-time video editing. The script that runs the sensor is in C++, and the API for the video editing software (vMIX) is executed with HTTP protocol. I'm hoping to use that C++ script to control the video software (as some of the editing is dependent on particular feedback from the sensor), and wanted to see how to execute a HTTP command from a C++ script.
View 3 Replies View RelatedI have a Third Party MS-DOS program, RUN.EXE
RUN.EXE do the following:
1. Read FILE.INP as input file and run its code execution.
2. When finish, RUN.EXE will produce FILE.OUT as the output of its code execution.
3. However, if calculation made in the code execution come to unsatisfied condition, RUN.EXE will terminate without producing FILE.OUT or partially produce FILE.OUT.
I want to write a program using MFC which I can set a several input case. The program should be able to:
1. Call RUN.EXE.
2. Wait for RUN.EXE to exit.
3. Continue with other code.
I can't modified RUN.EXE. I can't have RUN.EXE callback my program to let know it finish its work.
Are there any functions to call RUN.EXE, a MS-DOS program? Are there any way for the program to check if RUN.EXE finish its work and exited?

View 7 Replies View RelatedI am having a hard time with some of my homework, specifically regarding how to printf floats. I can't seem to print the number i want out using float, it just becomes a jumbled mess.

Thats the code I currently have, I've probably tried everything to get the number to come out, but I just cant seem to figure it out. It should look like this, but with different numbers and stock:

Amount of Investment: $10,000.00 Value of Shares Sold: $10,234.90 Amount of Gain/Loss: $234.90 Percent Gain/Loss: 2.35%
However, this is how mine turns out:
Code::Blocks
Enter share purchase price for LRCX=>23

I have the following line of the code. Now I want to save the content to a string. Is there a quick way for me to do the conversion using the same arguments/codes of printf?

View 10 Replies View RelatedFor easier debugging, I would like to execute an own (predefined) function while beeing in a breakpoint (e.g. print some variables to a file).
Does there exists such a feature?
e.g.
- run program to a breakpoint
- a) press a keyboard-function-key (which calls that predefined function)
- b) or hover with cursor over a variable (and modify somehow the routine which shows its content on the screen)?
i need to create an small windows form, with some buttons, and then those buttons will "exectute" an action on a remote webserver.
Im searching with http requestings and didn't find nothing useful for what i need.
The basic thing is that i just need to press "EXECUTE" and then c# will press one link in the Webserver. I do not need any feedback from the page. I just need that C# execute a link like localhost/startbackup.php then the actions from the startbackup.php will run.
I do not need any information regarding if the page was successful executed or not, or even if it opens one window. Nothing.
I'm wondering whether it's possible to implement MPI to execute a process in parallel from deep within a C++ solution.
I've created a solution on VS2005 that links to several static libraries, and within one of these libraries there is a set series of tasks that require execution many times - they're independent so I'd like them to execute them using MPI if possible to speed up the run time.
The pseudo-code is:
Code:
for(i = 0; i < n; i++) // n is number of times to execute process {
PerformTask(data[i]); // perform the tasks required for each iteration of process
}
So, instead of conducting the tasks within PerformTask() in series n times, I want to split the array data between multiple processes such that they can each be allocated an even proportion of data to perform the tasks on. Pretty textbook reason for wanting MPI, right?
Now, I've read up and understood the basics of MPI implementation, but all the examples I've seen are called within the main() function of the program. But I need to do all this from within a static library, is this possible?
I've made some early attempts at implementing this, but get an error indicating the process wasn't initialised: "Error encounted before initializing MPICH", which I assumed would be due to trying to make the MPI calls outside of the main() function.

I'm making my way through most of this assignment that I have, but now it seems like I've run into a bit of a roadblock. The issue that I'm having is not being able to printf a series of ints that I thought I had previously defined in another function. I don't want to clog up this post with the entire code, so I'll just post one function that defined an int to give an example. I will upload the whole thing upon request however.

I just checking but confused with float. in that code same size int, and same type double are working but float showing nothing in printf..why?? i'm using GCC compiler int 32bit win7 os
Code:
#include <stdio.h>

char arr[10] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9' };
printf("Size of char=%c

The overall width of the line is 20 characters. How can I center a string using print so that
title becomes
space-title-space
i have something like this so far Code: fprintf(myfile, "%20s ",mystring);
How to store the value in this case.. The topic is called "limited summation".. The following is the guideline for this problem:
Write a program in a folder called "sum" with a source file of main.cpp that does the following:
•prompt a user to enter a maximum number of entries, make the prompt "max # entries"
•prompt a user to enter a threshold sum, make the prompt "threshold"
•using error checking logic, let a user enter base-10 signed numbers until at least one of the following conditions is true:
or the maximum number of entries is reached
or the sum of entered numbers has reached (>=) the threshold
•print the sum of all the entries, just the number and a linefeed at the end of the line
Error checking means entries that are not numbers are detected and ignored. You are to use printf and scanf in this assignment (no cin or cout).
I would like the following code to print: "Why doesn't this print?" and "I would like to print the sum of nc: 5". What am I doing wrong.
#include <stdio.h>
//Use to test ideas and formats//
main() {
int c, nc;
nc = 0;
[code]....
My result as compiled by gcc -o testing testing.c
This prints.

I have not figured out how to sum and print as the above code indicates, which complicates my ability to do many of the exercises in "The C Programming Language". I am using a MacBook gcc compiler and X code as well. I cannot get the last two printf functions to work. I did the temperature example with "while (fahr <= upper)" and the printf printed.
I have a condition and I would like to instead change the condition so that it would execute the previous statements after else statement.
It seems hard to explain but I'll try my best to illustrate anyway
if (condition)
<statement1>
else
<statement2>
So I would like to change the condition so that
if (condition)
<statement2>
else
<statement1>
And the condition is
Code:
if(!lightStateAtNextLink || !bIsLightEnAtConnection && nLinkNext.IndexToAttachedNode() != pVeh->_.stAutopilot.m_dwNextNode || bIsLightEnAtConnection && nLinkNext.IndexToAttachedNode() == pVeh->_.stAutopilot.m_dwNextNode)
And I have changed that to this. Is this correct?
Code: if(lightStateAtNextLink && bIsLightEnAtConnection || nLinkNext.IndexToAttachedNode() == pVeh->_.stAutopilot.m_dwNextNode && !bIsLightEnAtConnection || nLinkNext.IndexToAttachedNode() != pVeh->_.stAutopilot.m_dwNextNode)
Im going through a C tutorial and im going to create a Database as part of the course. Im just in the very beginning of the project so its a very simple program so far.
Code:
#include<stdio.h>
main(){
/*Variabler for att lagra information om skiva*/
char title[200];
char artist[100];
int tracks;
int price;
[Code] ....
The first switch case statement takes me to the menu of choice, 1 or 2. However, chosing menu option one and trying to input a title or artist name, the program crashes.
Next, going into menu option 2 and then trying to print out, for example, title nothing happend. The process just ends.
Again, im sure this simple prototype is full of errors ....
