C :: How To Test Program That Opens Files In Command Line
Mar 10, 2014The below program is supposed to display the contents of all files listed in the command line. When I try to run the program I get the fatal error "Debug Assertion Failed" Expression: file != NULL. I've done some researching on the matter and I gather it might be because I don't have any files listed in the command line?
How to enter files in the command line! I opened the Command Window in Windows XP and tried typing in "C> argc" and "% argc" (argc being the name of the file containing the below program) without any luck.
Code:
#include <stdio.h>
#include <stdlib.h>
int main (int argc, char * argv[]) {
int ch; // int to hold EOF
int count;
FILE *fp;
for(count = 1; count <= argc; count++) // agrc loop

C/C++ :: Using Program That Calculates Test Average Using While Loop?
Sep 23, 2014I am working on a program that calculates the average of a list of test scores entered, with the list ended with a negative score (which is not calculated), as long as a user enters a name.
#include<iostream>
#include<string>
using namespace std;
int main() {
string name;
double score = 0.0; //user input score
[code]....
I have gotten the while loop to function. The problem lies in the calculation in the average of the test scores, such as when I enter the scores 87 76 90 -1 , which is supposed to give an average of 84.3 but my result when outputted is 86. what the problem is and what I can do to fix this error?
C :: Using Arrays - Program That Prompts For And Reads In Test Scores
Feb 11, 2013Write a program that prompts for and reads in test scores. You may assume that valid test scores will be integer values between 0 and 100. You may also assume that the user will not enter more than 35 test scores. Use a preprocessor directive to define this value. User input will be complete when the user enters a -1 for the test score. When all of the test scores have been entered, the program will print out the scores. Use a while or do-while loop to read in the values. Use a for loop to print out the values.
Sample output:
Enter test score 1: 88
Enter test score 2: 67
Enter test score 3: 74
Enter test score 4: 94
Enter test score 5: 79
Enter test score 6: 56
Enter test score 7: -1
Number of scores entered: 6
Test scores entered : 88 67 74 94 79 56
C++ :: Test Scores Program With Pointers - Calculate Average?
Apr 7, 2013I have created a program that allows for a user-defined number of test scores as input. After the user enters these scores, the program calculates the average test score. Here is my code:

C++ :: How To Use Two Header Files In Program
Sep 17, 2013I want to use two header files in my program. Here is exactly what I want to do.
-In the first header I have a binary tree and a structure.
-In the second file I have another functions that need to use the structure in the first header.
-I also want to use a function from the second header in the first.
-And finally I want to do actions with both headers in a "main.cpp" file that contains only int main() function.
How to include the headers in each other and in the main.cpp to be able to do the actions above?
I try to include the first header in the second one and the second one in the first header. Then I include both headers in the main.cpp file. But the compiler shows me many errors.

C++ :: Uploading And Downloading Files In A Program
Feb 19, 2015I understand I can do this via a php file on a server, but I don't understand how I can communicate with the php file from c++ code on my machine. Is there some library function I can use to load the html form or data object to hold the php form? Also whats the vibe on amazon EC2 cloud computing servers? It may be out of the scope of this simple program I have uploading and downloading XML, but is this the technology of the future, and should it be embraced now?

C :: Program To Match Strings From Input To Files Using Dfa
Sep 2, 2013'Write a program to match the user input string with the contents of text files and give the result as to which files contain the input string. This has to be done by using finite automaton.' (Any language can be used) So basically, the user will input a string (in the command line or a gui) and "we must pass the text files to the DFA" (I'm double quoting this because it's precisely what my professor told) and then display those files which contain the string. The string can be hard-coded, ie,the user will get the output file that contains a specific string. ex: 'hello'. The problem is, I have never done any program on DFA so I'm at a loss. how to write the program. Should I read the files first and then use some 'switch' or 'goto' conditions for the DFA? Below is a code I found on the internet for simulating a DFA accepting a specific string.
Code:
s: accept = false; cin >> char;
if char = "m" goto m;
if char = EOF goto end;
goto s;
m: accept = false; cin >> char;
if char = "m" goto m;
if char = "a" goto a;
if char = EOF goto end;
goto s;
}

C++ :: Program Needs To Compile Various Source Files At Runtime
Oct 30, 2014My program needs to compile various source files at runtime.What is the most elegant way to compile cross platform with g++ from within my program? Is there a gcc-library I can use? I know that I could use popen() to open a Unix pipe and call g++ as command line tool. But first it isn't really cross platform and second it doesn't seem elegant to me.

C/C++ :: Program That Can Merge Files From Command Line In Li
Sep 22, 2014I have written a C++ program that is supposed to open two text files (prog2a.dat and prog2b.dat) and write the contents of a specified range of lines to an output file (outfile.dat). I wrote a program that based on the example we were given (to take lines 5-15 from the first file and lines 4-12 of the second file and merge them into the output file) works perfectly. However, after asking my professor for some clarification on another part of the assignment, I found out I have not done this correctly. I have the code written so that it will always output the range of lines I mentioned earlier, but the program is actually supposed to allow the user to merge the files from the command line using whatever range they want by typing in the following command:
prog2 in1 5-15 in2 4-12 outfile
But I'm not sure how to tweak my current program to allow this to be done.
Here is the code that I have written, keep in mind that this works properly for the way it is written, but not how it is supposed to work for the purposes of the command line (hopefully that makes sense):
#include <iostream>
#include <fstream>
#include <cstdlib>
using namespace std;
int main() {
// Create output file
std::ofstream outFile("outfile.dat", ios::out);
[Code] .....
Is there any simple way to make this work as I described using the command line? Also, I am supposed to break this up into three files, a header file, the program file, and a test file (the test file contains main() and should close the 3 open files and display any error messages), but I'm getting really confused as to what should go in the header file. I know the header file should contain class definitions and constructors, but don't really know how to make that work for this specific program?
C/C++ :: Merging 2 Files Program Starts But Does Not Complete
Oct 9, 2014I'm having an issue with merging two files. Basically, my instructor gave me pseudocode and two files to merge together. Each file (a male client and a female client file) has three names and id numbers inside. The finished MergedClients.rtf should have all six clients in ascending ID order. I wrote the C++ code and after combing through a couple times to fix a few errors, it finally ran. The problem is it starts the process, but it doesn't ever finish.
I tried changing some of the bool expressions thinking I mixed up the true and false parts. After that the program ran and it created the new output file, but the file was empty. So, I don't think I mixed any of those expressions after all.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main(){
ifstream inFile1;
ifstream inFile2;
