C :: Program To Write Even And Odd Integers Into Different Files
Sep 7, 2014
-Create three files namely all_numbers, odd_number and even_number.
-Get the number of records and the numbers to store from the user.
-Save all the numbers in "all_numbers" file.
-Read each number and check whether it is odd or even.
-Store the odd numbers in odd_number file and even numbers in even_number file.
-Finally, print the numbers stored in odd_number and even_number files.
The output of the program will look like this.
How many records that you want to store :41
2
3
4
The data are written too the respective files.
The even numbers are 2 4
The odd numbers are 1 3

#include <iostream>
using namespace std;
int main()
{
int num = 2;
int count = 0;
while (num <= 100)
[Code]...
The code works fine but I need the results to print out like
2 4 6 8 10 12 14 16 18 20
22 24 26 28 30 32 34 36 38 40
instead of
2
4
6
8
10
12
I don't know how to do this.

I am trying to make a simple program, I would like it to be able to do the following, Write a program that opens two text files (input1.txt and input2.txt) for input .The program should write the followings in the two files. input1.txt:
This is the first line in input1.txt.
This is the second line in input1.txt.
This is the third line in input1.txt.
This is the fourth line in input1.txt.
input2.txt:
This is the first line in input2.txt.
This is the second line in input2.txt.
This is the third line in input2.txt.
What would be the best way to go about doing this? I wrote the program below, but I don't think that it works.
#include <iostream>
#include <fstream>
#include <string>
int main()
{
using namespace std;
string input1;
[Code]...

I need to write a program that merges the numbers in two files and writes the results to a third file. The program reads input from two different files and writes the output to a third file. Each input file contains a list of integers in ascending order. After the program is executed, the output file contains the numbers from the two input files in one longer list, also in ascending order. Your program should define a function with three arguments: one for each of the two input file streams and one for the output file stream. The input files should be named numbers1.txt and numbers2.txt, and the output file should be named output.txt.

There is one question :
Considerint A[10]={ ....................}; // already filled
int B[10]={ ....................}; // already filled
Using PIONTER NOTATION ONLY, write a function that receives two arrays of integers like A and B above. The function should swap the values in A and B. You may NOT use array notation [ ]. Also, you have to use pointers to move among array cells. Note: Both arrays are of the same size, and size should be variable in the function.

write a function accepts two arguments, an array of integers and a number indicating the number of elements in the array. the function should recursively calculate the sum of all the numbers in the array. Demonatrate the use of the functions in a program that asks the users to enter an array of numbers and prints it sum
i had done this but it wont work
#include <iostream>
#include <conio.h>
#include <iomanip>
using namespace std;

I try to write my data into two different files and i just use something like this
ofstream myfile;
myfile.open("phase 1.txt");
if (myfile.is_open()) {
for(i=0;i<M; i++) {
[Code] .....
But it only generate the first file. How should i modify this?

I would like to read in binary files, then write them to another file.
I write a code, what works perfectly, if I would like to just copy the file to another. But I want to make it a little other.
If I open a file in hex-editor I also can see the ASCII values. But I would like get the ONLY the hex values to the other file.
For example:
d5 57 4f ad 30 33 0b 4e 49 a7 05 18 c4 90 66 d8 45 ac 39 3e 7d f1 a8 02 80
14 20 90 6e 20 12 38 0c 65 4a 28 d2 80 72 04 20 a9 4a 82 84 60 6a 0b 25
59 4c 30 c8 69 c0 ec fa 36 ed 3a da b1 9a 82 02 e0 bb 7e 41 87 02 f6 10 34
eb 95 93 63 01 6b 8d e1 d7 43 c3 df 92 5d 8a ed 57 61 4e 36 07 2a d7 56 2b
b5 0e 55 83 b4 76 8c b7 61 77 0e c9 76 0c 81 1b 01 63 0c 8b 73 57 d5 6d 4c
0c c2 0d 52 45 18
How could I make it?

need to create a program for the following problem
1.Program takes messages as input at a rate “X” msg/sec, and outputs those messages at “Y” mgs/sec in a file.
2.The peak value of X can be 10msg/sec, and Y can be at max 5msg/sec. System should be designed in such a way that it can handle the peak input rate of 10msg/sec for not beyond 5 minutes.
3.Message contains following fields – unit id, timestamp, temperature.
4.Input data to be read from a file. Output data to be written to a file.
5.For testing design 3 types of profiles –
a.Profile 1 for 10 min – low rate, i.e. X = 4 msg/sec on an average throughout the period.
b.Profile 2 for 10 min – Max rate, i.e. X = 10 msg/sec for 2 min; then a sleep of 2 min, then repeat the same pattern till complete period
c.Profile 3 for 10 min - Max rate, i.e. X = 10 msg/sec for 5 min; then no traffic for next 5 min

I am writing a program to hide files behind other files using Alternate Data Streams in Windows NTFS file systems.
The program is as follows:
Code:
#include <stdio.h>
#include <stdlib.h>
int main(void){
char hostfile[75], hiddenfile[75], hiddenFileName[15] ;
printf("Enter the name(with extension) and path of the file whose behind you want to hide another file: ");
scanf("%75s", hostfile);
[Code]...
The complier is showing error as "Extra Perimeter in call to system" but I am not getting where?

In my program I open two files and write data into each, and close them. this is done in a while loop.
int main() {
while() {
myFile = fopen("file1.txt","w");
myFile2 = fopen("file2.txt","w");
// write data into files using fprintf() in a for loop
fclose(myFile);
fclose(myFile2);
}
}
However, after some iterations the fopen() for myFile2 fails.
Debug assertion failed!
Program....
File ......srcfprintf.c
Line 55
Expression (str != NULL)
I have not been ableto locate the bug in the code that is causing the failure.

I compiled a simple program using a function to add two integers, in order to understand the difference of calling by value vs by reference.
Code:
#include <stdio.h>
int add(int a, int b, int sum);
int main()
{
int a, b, sum;
printf("Please enter two integers
");
scanf("%d%d", &a, &b);
[Code]...
I used these two (one, two) pages I found in the net while studying the subject. So here are my questions...
(a) Do I understand correctly that in the above code all a, b and sum are passed by value?
(b) If I wanted only sum to be passed by reference, how the above code would change?
(c) If I wanted all (a, b, sum) to be passed by reference, how the above code would change?

I created a program in C that opens a text file and read integers.
File `numbers.txt`:
> 5 6 4 6 3 4 1
I use some restrictions with the `fscanf()` library and read the file, just for the record, and if everything goes fine I proceed to the next part of code (I know I could use `fget()`, but this is how I done it).The next part of the code will be this:
- First, I want the program to read the numbers from right to left. I look for an answer in google and many C courses, but I couldn't find a working solution. I think that the code is pretty simple, though I can't find it. **To be clear for the next part, we read the numbers from right to left.**
- Then, this is the hard part for me: I want the program to read the numbers and if the next number is higher (**not equal**) than the last one to keep it in memory, **only if it's higher than the last.** This can be continue for **1 through 500.000 numbers.**
- Then when the procedure done, I want to print how many numbers are greater than the last one and save it to a file, which I can do it if I solve the last problem.
We have the below numbers:
5 6 4 6 3 4 1
The program starts to read the numbers from right to left.Now which and how many numbers are greater than the last one?
The answer is 3 numbers:
5 6 4 [6] 3 [4] [1]
Then the program will print the number 3 with a message and save it to a file called `xxx.txt`. I am posting the `main` code, not all the code just what you need to solve the problem:
Code:
#include <errno.h> // macros for reporting and retrieving error conditions
#include <stdio.h> // load main C library function
#include <stdlib.h> // need that for many reasons ;)
#include <string.h> // loads various of characters functions
}
[code]....
In conclusion, I want 2 pieces of code:
- One to read the numbers from right to left
- One to make the above procedure

Add a program that declares two arrays of 5 integers each. Provide one function to load one array with random numbers from 1 to 25, another to fill the other array with user supplied values, and a third function to print an array. The main function should declare the arrays and use the functions to fill each array and print them both.
The code i have so far is
#include <cstdlib>
#include <iostream>
using namespace std;
void printaaray(int printarray1[], int printarray2);

I have done some programming or rather have written and implemented some algorithms in code (is there a difference? :-)) but am having some teething problems with a project I am currently working on.
To start with I am simply reading in the data from a .txt file into a vector. This is the code that I currently have:
Code:
#include <iostream>
#include <fstream>
#include <cerrno>
#include <vector>
[Code]....
This compiles fine but currently outputs a different integer everytime I run the program. I can remember having this problem when I started coding before using a different language and if I remember correctly it was quite easy to resolve. I thought it was because I had missed off the 'return 0' but it is something similar I think.

I want to pass some strings and int values from a file to my program.. if i was using c i could do it like
scanf(p,"%s %s %d %d",&str1,&str2,&num1,&num2);
I don't want to get the whole line just the values one by one if i wanted the whole line i could do it with getline(); now that i want the values one by one how do i do it ...

I know it would be easier to create an int array, but I want the program to create integers as the user requests. For example, if the user enters 4, the program creates 4 integers with the names input. Each integer is better as an individual integer, not an element in an array.I'm not sure if this is a possibility with C++.

This is the problem :- Write a program that keeps reading integers until user enters -1, then it prints the maximum and the minimum among all numbers (-1 should be ignored).

I'm trying to get my C program to compile but it's not working at all. I've programmed a little in C++ before but I'm not used to C. Here's my program so far:
Code:
int main(void){
// Establishes variables
int num1, num2, product;
float quotient;
[Code] .....
It keeps giving me an error message as follows:
"/usr/bin/ldrelabwk2: file format not recognized; treating as linker script
/usr/bin/ldrelabwk2:1: syntax error
collect2: ld returned 1 exit status"

Write a program that asks the user to type 10 integers of an array. The program will then display either "the array is growing", "the array is decreasing", "the array is constant", or "the array is growing and decreasing."
(Hint: compare consecutive numbers in array and check whether it is increasing or not or constant) I wrote the program very well, but do I have to use "bool" like in c++ ? I haven't known how to code in c++ yet.So, I don't want to use "bool" in C.
I also wrote code about it but it looks like backslash and one,two,three,four,five how can I do it like this ?

The question is "Write a program that uses a while loop to read a set of integers from an input file called "data.txt" and prints the total number of even numbers read from the file."
Code below is the program I have created so far. I keep getting the window to pop up but not stay up so I am assuming I am doing something wrong.
#include <iostream>
#include <fstream>
using namespace std;
int main() {
std::fstream input("data.txt");
if (!input.is_open()) {
std::cout << "There was an error opening data.txt";
