The last number in the numbers.txt file is: -1, and I am not allowed to include it in the calculation of total, average, etc.
I tried to make an if statement to not include -1 but, I can't figure it out. This compiles with or without my num == -1 statement.

I wrote a code that counts numbers of words in a sentence, simply by counting spaces... but instead of showing a true number it shows a wrong number.
#include <iostream.h>
#include <conio.h>
int check(char eh[10000]) {
int he=0;
for (int i=0; i<=10000 ;i++) {

How I would go about counting lines from a file at the same time as extracting words? I need to know the line number to output what line the word is misspelled on. I tried getline and using sstreams but I could not get it to work.
void SpellCheck::checkValidWords(const string& inFileName) {
string eachword;
ifstream istream;
istream.open( inFileName.c_str() );
if ( !istream.is_open() ) {

I 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 Relatedit looks like a popular method for determining the total lines in a file is to read the entire file character by character in search of ' '. I have a file with 5 lines, but for some reason this code isn't finding any instances of ' '. Is this possible? Is there a better way to get the number of lines in a file?
The file looks like this:
Code:
NAME: John
FRIEND 1: Steve
FRIEND 2: Andrea
FRIEND 3: Ken
OCCUPATION: Programmer
Code:
FILE *f = fopen(currentFile, "r");
if (f == NULL) perror ("Error opening file.

I was trying to make a function that would return how many lines are in a certain file. I was looking at [URL] which talks about how to count how many characters are in a text file. I just want the number of lines with in a file.

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)?
How can I count the occurrences of each character in a text file and then organize them by most occurring?
View 1 Replies View RelatedI'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)
perror("input file open failed");

The user will first enter the file name to be processed. The program can do the following 5 tasks:
1. Count the number of words
2. Count the number of alphabets (without punctuation marks)
3. Count number of sentences.
4. Count the frequency of each vowel.
5. Count frequency of the following three words individually: FAST, computer and engineering
There should be a proper menu through which the user can select the desired task. The program should continue until the user asks to terminate it.
Here is what i have done so far:
#include <iostream>
#include <cstring>
#include <fstream>
#include <cstdlib>
using namespace std;
int main(void)
{
int opt=0; //option number
ifstream fin;
string filename;

There are a few problems.
1- When I enter option 'q', an infinite loop starts.
2- The first time, the program gives the correct value. After that, each time it gives answer ZERO.
3- The last part is not working. I experimented something which failed. I don't know how to do the last part.
I have to write a program (on linux) which will count character, words and lines like wc linux command. I'm trying to write this for last 3 days... First part of app I did and it works fine - command line options to choose. Then I've got a function read_file which I have to use to read a file. One of the options is to get the file name from user and if user will not type any name then the standard file is ubuntu dict file /usr/share/dict/words, this is not working as well...
Counting characters and lines is working fine but because I don't know how to get text from read_file wrote code to read file interior this functions. Words counting is working partly - everything is fine until there are two or more spaces, tabs one after another then counts extra words. Finally I need child processes in words and lines counting functions. Parent process should waits for all childs to finish and should be pipes to submit character counts back to parent process. How to do all this things with processes...
Code:
#include <getopt.h>
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#include <errno.h>
/*size of character buffer to read in a file. */
#define BUFFSIZE 1000000

I've been struggling with this for a while, I have to write a function that accepts a word (in my case the word is "the") and file pointer, and counts the number of times the given word appears (case insensitive) within the file associated with the pointer. This means the two words "the" and "THE" should both be counted.
Here is my code:
int WordCount :: countWords(string wrd) {
int counter=0;
string temp = "";
while (getline(*file,temp)) {
for (int i = 0; i < temp.length();i++) {
[Code] ....
This is what I have come up with, but I get an incorrect value. It was suggested to us to consider using the strcpy() or strstr() functions, but I don't know how to use them.

So I'm trying to count the number of lines in a text file that is inputted by the user. Also the code doesn't sum up the last number of the text file (exmp it calculates and print only 14 from 15 numbers). I'm a beginner in c++ programing.
View 3 Replies View RelatedI'm creating a program to read information about class schedules at my school, reformat the information, and allow the user to search for specific semesters. There are eight fields of information. I'm reading the info from a text file using eight parallel arrays, but I'm having trouble declaring the arrays. I can run this code in one compiler (Dev-C++) with no problems, but I get errors when trying to compile it using Visual Studio stating that arrays must be declared with a constant value. I have a loop to run through the text file, with a counter to increment with each subsequent line, then I create a constant int equal to the counter, and declare the arrays of size equal to the constant int. Here's the section of code in question:
// Counting the number of lines in the text file
inFileForLines.open("CIS225HW1DA.txt");
string countLine;
int numberOfLines = 0;
//Discarding the first line of the text file containing only column headings
getline(inFileForLines, countLine);

Write a program which reads a stream of numbers from a file, and writes only the positive numbers to a second file. The user should be prompted to enter the names of both the input file and output file in main(), and then main() will open both files. Another function named process() must then be called to read all the numbers from the input file and write the positive numbers to the output file. Note that you must pass the open stream variables for each file as arguments to the process() function, and that you need to (always) double check that the files opened successfully before using them.
This is what I have so far but its not working out!

So I'm supposed to create a program that will read off words from a .txt file,and use a function to count the number of vowels in each word and then display the specific vowels and their frequencies. ex. if the word is: butter the output would be:

o:0
u:1

2. when user typed the integer not between 0 to 9999, the program print out the numbers of integers that were typed.

How to make this program that the output is a number that counts up to infinite (or we say just like a timer but there's no minute just all whole number counting up ) using for loop ? and when the number changes it also change in color !
and the color of a number is according to the color attribute of console output.
