C :: How To Read Characters From File
Dec 29, 2014I'm new with C language. I got task to do . Actually there are 2 points. Both should be done with reading text from file. write down all letters from text in reverse alphabetic order (each letter 1 time).write down all words in random order.
I'm stuck with first point. Below code gives me entire text, but i need unique characters only. Text file contains few sentences.
Code:
#include<stdio.h>
void main( ) {
FILE *in;
int ch;
if ( (in = fopen("test.txt", "r") ) != NULL ) {

C/C++ :: How To Read And Write Certain Characters From A File
Oct 12, 2014How to read some characters from file, I know we can move a pointer to some position using seekg() & seekp() function, get current position of the pointer through tellg() & tellp() functions. By moving the pointer to appropriate position using seekg(), we can read the whole line using getline() function. But is there any function which read certain characters from the current position of the pointer and write certain characters from current position of the pointer.

View 2 Replies View RelatedC++ :: Read String Of Characters And Write With Punctuation Removed
Oct 13, 2014Write a program that reads a string of characters including punctuation and writes what was read but with the punctuation removed.
This is how i did it:
string x("#punctuation!?=");
cout << x << endl;
for(unsigned i = 0; i < x.size(); ++i) {
if(ispunct(x[i]))
x[i] = ' ';
cout << x << endl;
I am just not sure if thats how they want you to do it because it doesn't remove the punctuations it just replaces them with a space.
C/C++ :: Program To Read In And Count All Printable Characters (ASCII 32-126)
Feb 12, 2014I'm writing a program that reads and counts all the printable characters (ASCII 32-126)found in a text file.
For example if the text file read: Why so serious?
The output to the screen would display(in order of ascii value however):
Character-----Total
W--------------1
h--------------1
y--------------1
s--------------3
o--------------2
etc...
However, I don't think it's reading any of the characters.

C :: Read Contents Of A File Using Low I/O Read Statements
May 15, 2013I want to read the contents of a file block (512 bytes) by block using low I/O read statements. Each record is 64 bytes long and has a pre-defined structure. The first 4 bytes are an unsigned integer; the next 20 bytes are ascii text, etc.
I have a buffer which I can access with buf[0] to buf[63] to read the first record and then buf[64] to buf[127] for the second, etc. However, I was wondering how to map a record so that I can refer to an integer as an integer and a float as float, etc. I can't create a struct and move the 64 bytes to it, as I will have alllignment/padding problems.
What is the standard way to deal with records in C?

I get this data from a site and I copy paste them to create a .txt file for input (I do this my self, no program involved).
When the program runs it ends up like this on netbeans:
0 [main] program 2336 open_stackdumpfile: Dumping stack trace to program.exe.stackdump
When I type the input file my self it works fine. When I copy the data from the site that the problem occurs, it looks like those strange characters are causing the problem (notice the ????? are some drawings on text).

C++ :: Counting The Number Of Characters In TXT File
Feb 22, 2015I have recently hit a stump with C++ and have been getting pretty frustrated with this assignment. I just can't seem to find out how to start the assignment. Basically for the first part of the assignment, I need to find the number of characters in this .txt file my teacher provided for me. The only exception is that I can only count the actual letters themselves, not spaces or punctuation. How would I go about doing this? I have read about functions like isalpha but can't figure out on how to fit them into code to do the first part of this assignment.
View 2 Replies View RelatedC :: File I/O Reading In Characters And Numbers
Dec 1, 2013I think it comes from having to align the data in the output file. How to start this is to use a function to read in all the characters using a while loop. Then read in all the digits in a separate function. When it comes to outputting the data in the correct format I'm lost, so for now if I could figure out the functions that would be awesome. A final note we have not gotten to using strings so the I'm trying to use getc, fgetc, and ungetc.
Write a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: Each line contains a students first name, then one space, then the students last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file. The data in the output file will be the same as the data in the input file except that there will be one additional number at the end of each line: the average of the students ten quiz scores.
The output file must be formatted such that first and last names appear together in a left justified column that is 20 characters wide. Each quiz score should be listed in a right justified column that is 4 characters wide, and the average should appear in its own right justified column that is 10 characters wide.
Note that if a student has fewer than 10 scores, the average is still the sum of the quiz scores divided by 10; these students are assumed to have missed one or more of the quizzes. The output file should contain a line (or lines) at the beginning of the file providing appropriate column headings. Use formatting statements to make the layout clean and easy to read.
C++ :: Reading From A File With Characters And Numbers
Apr 17, 2014I need to open a file that has multiple lines that look something like this, " black box 100.01 33.5 78.93". What this shows is the coordinates of the black box. Lines will have different objects with different coordinates. I need to create a loop that will read this file and tell me when a black box is found by displaying a message. I don't need to know how to create this file. I don't need to display the entire file but rather have it search for black boxes.

Apr 3, 2014I currently have a .csv file that should only contain numerical values however there are errors in some columns that mean there is text included. I am wondering what the best way of going about removing these characters would be.
I am looking at using : str.erase(std::remove(str.begin(), str.end(), 'xxxxxxx'), str.end());
For this I will need to read my data into a string and then remove the alphabet from that string. I am currently doing this like so (I use the '?' as a delimiter because I know there are none in my file).
#include <iostream>
#include <fstream>
#include <algorithm>
using namespace std;

char chars[] =

C/C++ :: Counting Characters In A String / File
Jan 19, 2015I have the following program
#include "stdafx.h"
#include "string.h"
#include "ctype.h"
/*selection sort*/
void swap(int A[], int j, int k) {
int p = A[k];
[Code] ....
Theoretically it should cound the number of apperances of each character in a string, but:
1) It is counting characters from letter "j" upwards thus all asci characters below "j" are not counted, why is that?
2) I want also to make this code calculate the number of apperances of each character in a txt file. How to do that, i know i have to open a file in read mode, that's all (I am new to c programming)?

C :: Counting Number Of Characters Copied To File
Jul 21, 2014I'm trying to copy a file into another file and copy the number of characters copied but my while loop doesn't even enter into a loop indicating the file is already at the EOF file character. I've confirmed this by placing the printf() statement inside the while loop, which doesn't print anything and by keeping it out of the while loop and changing the chars_copied to something like 9, it prints 9 for number of chars_copied. I don't understand why the file is already at the EOF character, I've tried this with a few more files, it's the same result.
Code:
#include <stdio.h>
int main(void){
FILE *input_file, *output_file;
int c, chars_copied=0;
if((input_file=fopen("C:workmarks.txt", "r"))==NULL)
