C++ :: ReadFile Function Cannot Read Entire Executable File
Mar 30, 2014I am writing a program which compresses files into .zip files.
Here's my problem: Whenever I want to compress an executable file, my readFile function does not read the entire file. When I extract the .exe I get a very tiny and incomplete file.
Here's the function I use to read files:
std::string miniz_wrapper::readFile(FILE* f, int MAX_FILEBUFFER)
//MAX_FILEBUFFER has a default value of 65536 {
char* tmp;
std::string tmp_s;
int count = 0;
[Code] .....
Prior to reading, every file is opened using fopen with the mode "rb".
C/C++ :: Program That Read A Number From Keyboard And Print Separated Digits To Screen
Feb 18, 2015Basically this is what i need to do. Write a program that reads a number from the keyboard, separates it into its individual digits and prints the digits to screen, each on its own line followed by the same number of stars as itself.
For example, if the number is 2339 the program should print
9 *********
3 ***
3 ***
2 **
So far i have managed to separate the number and have them on different lines, but how to implement the stars onto each line with the number!
My code so far:
int main() {
int n;
printf("number? ");
scanf("%d", &n);
while (n > 0) {
printf("

C++ :: Print Custom Area Of Screen - Save As Image File
Sep 9, 2014I am trying to automatically(periodically) print screen a custom area of the screen, save it as an image file (the image will have the same format always), and then use OCR to get the text in the image as usable string variables. Is this doable? I was looking into tesseract OCR but I find it a bit unclear.

C :: Opening A File For Read Only On Screen

C++ :: Convert List Of Binary Numbers From A File Into Decimal And Print To Screen
Sep 23, 2014I am trying to make a program that will convert a list of binary numbers from a file into decimal and print the decimal to the screen. I have no problem doing the conversion, the problem comes up when our teacher wants the input file in a format as such:
3
10110101
11111111
10101010
The first number is supposed to tell the program how many different 8bit strings it is going to have to convert, and then the following lines are those binary numbers.
I am not very experienced with file inputs, and I know how to open files and read lines in.. The problem is, how to say "ok the first line says 3, so now I have to convert the next 3 lines" . I am assuming it is just a simple loop that I am missing....
C/C++ :: Read From Dat File And Produce Output On Screen - Error C2664
Feb 5, 2014My professor wants me to write a program that will read from a dat file, and produce an output on the screen based on the file. I don't understand why I am getting this error. I suspect it has something to do with the number of characters I've told it to read.

C :: Read And Print To File?
Jul 15, 2013Ok, I think I got the main idea of the I/O chapter. Though I think I might be oversimplifying the program because I am getting an interesting error.
Goal here is to read numbers from a file and print the numbers with totals for two of the columns and a calculated average for of the totals.
NOTE: The tables for the info from file look a lot better on my end. [QUOTE] seems to mess it up a bit from copying and pasting.

C/C++ :: Read From File And Print Output To File?
Apr 20, 2014I know this is how you read from a file. I also want to print my output to the same name of the file plus ".txt". So if my file is called "text" I want to print it to a file called "text.txt".
#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>

Would it be something like this? Is it better to use "a" or "w" in the fopen? I want to write to it several times.

C :: Unable To Read Data From Text File And Print It
May 12, 2014I am having trouble in reading data from my text file and print it out exactly like how it looks like in the text file. The problem im having is it will not read the last y Coordinates of the point. it keep reading the second last point for y coordinates which is wrong.
my text file is
0.0 0.0
0.0 1.0
1.0 0.0(but it read until here)
0.0 0.0(suppose to read the last point which is here)
For your information, this is my 1st year degree assignment in C programming. It is to create a program which can read text file (manually create) and print it out in a program and calculate the area for the polygon using ADT function ( .c and .h files)
*This is the code for my read file function*
Basically this accepts a Polygon and a file pointer as parameters. It reads the polygon point data from the file, pass the read data to plg_new() to create a new Polygon and returns the new Polygon created.
Code:
polygon *plg_read(polygon *New_polygon, FILE *Coord) {
int i;
int numberofvertices=0;
int count=0;
char filename[50];
double xCoor[50], yCoor[50];
[Code]....
This is the second function my polygon new code. This ADT function basically creates a new Polygon with malloc(), initialize all ADT data members with its parameter values and returns the Polygon.
Code:
polygon *plg_new(double *xCoordinates, double *yCoordinates, int numberOfVertices) {
int x;
polygon *New_poly = (polygon *)malloc(sizeof (polygon));
if(New_poly->xCoordinates == NULL || New_poly->yCoordinates == NULL) {
free(New_poly);
[Code]....
This is the rest of the code if you need to refer to other codings.
Code:
/**
*@file polygon.c
*@brief Functions for polygon / Struct has polygon numberOfVertices, polygon *xCoordinates and polygon *yCoordinates

Basic food items can be further classified as meat, fruit, veg or Grain. The services provide by the class should be the ability to enter data for new food, to change data for food and to display existing data about food.
using this class definition write a main program to include a simple menu that offers the following choices:
1. Add food
2. Modify Food
3. Delete Food
4. Exit this menu
2. Read a list of numbers from a file and then print them out in reverse order. State whether the list is palindromic or not.

C :: Print The Inverse Number On Screen
Dec 25, 2014Print the inverse number. Ex: 2178*4=8712
Write down a program which can satisfy the prerequisite and print out the screen.
The answer is:
Code:
void inverse2 ()
{
int i,j;
for (i=1000;i<=9999;i++)
for (j=1;j<=9;j++)
if (i*j==inverse (i))
printf("%5d%2d",i,j);
}
I can't understand the double for loop.
for (i=1000;i<=9999;i++)
for (j=1;j<=9;j++)
And The meaning for
i*j==inverse (i)

C++ :: Check If A Number Is Odd Or Even And Print It To The Screen
Mar 8, 2013My objective is to check to see if a number is odd or even and print it to the screen just to make sure its working correctly.
The data file contains:
138
402 2 485
9
43
98 805
58
421
948 7 97
48
67
35
42
948
579 39 12
700 20 500 210
98
I can get the numbers to print fine using:
fstream infile1(argv[1]);
if(!infile1.is_open())
cout << "Could not open file";
else {
char listNum;
while(infile1.get(listNum))
cout << listNum;
}
However, when I check for odd or even numbers it will check each and every number.
printed like this (partial list):
1 is odd 3 is odd 8 is even
9 is odd
But it should print:
138 is even
9 is odd
I tried using getline, but it keeps giving me the errors:
invalid conversion from 'void*' to 'char**'
invalid conversion from 'char' to 'size_t*'
too few arguments to function 'ssize_t getline(char**, size_t*, FILE*)'
Here is the getline code, what am I doing wrong? I have tried switching things around, adding things. Just nothing works.
ifstream infile1(argv[1]);
if(!infile1.is_open())
cout << "Could not open file";
else {
char listNum;
getline(infile1, listNum);
cout << listNum;
}
