I have a program I have to do that counts the number of words in a text file. I have tried the code on 2 computers now since my programming teacher told me the code was fine. Here is my code:
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main() {
ifstream infile;
infile.open("tj.text" , ios::in);
[Code] .....
the text file looks like: one hello hi twenty-five billion fifty maths three thousand and two
output: count the number of text numbers: 4
I have a .txt file that contains, together with a few characters, columns of values that I want to save in different files like is written in the program (file 1, file2, file3 - a with x, b with y, c with z). The pattern of the source text file is like this:
known_vector frame1 151 65 0 frame2 151.000763 64.538582 0.563737
known_vector frame1 152 65 0 frame2 152.000702 64.542488 0.560822
known_vector frame1 153 65 0 frame2 153.000671 64.546150 0.558089
Until now I could manage to split the files, but the output gives me only zeros. First the program count the number of lines of the read text file, then it should display the desired columns of double values in three other .txt files.I've got for the three .txt files columns like this:
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
C program to count the number of lines in a text file and reverse the contents in the file to write in an output file.
ex :
input
one
two
three
output:
three
two
one
I have written below program to count number of words and lines and print the all the words.
#include <iostream>
using namespace std;
#include<fstream>
#include<string.h>
int main() {
ofstream outfile;
[Code] .....
Its compiling fine but when executed its displaying I infinite times...
#include <fstream>
#include <iostream>
#include <string>
[Code].....
When I try to run my program I get:
1>LINK : error LNK2001: unresolved external symbol _mainCRTStartup
1>C:UsersDocumentsVisual Studio 2010ProjectsCS 111Lab10Lab10DebugLab10.exe : fatal error LNK1120: 1 unresolved externals
What I'm trying to do is get my program to count the number of words in an inputted data file. I've attached the assignment directions
Attached File(s) : lab10_data_.zip (9.27K)
I want to count number of words from my textfile and then make the first word ToUpper and second word ToLower and do that for the rest of the textfile.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
namespace ConsoleApplication3 {
internal class Program {
private static void Main(string[] args) {
[Code] ....
I've a text file with 9 words and each word is written in a line. for exemple this is the list :
APPLE
ORANGE
MOON
CAR
CANDY
...
END
I'm gonna choose the fourth line and select the word that is in this line and work on. I tried lot of way but no result.
I have an assigment to make program which deletes from sentence all words with character count which is equal to pair number , for example - [ I like C ] and the result of this program should be [I C] because the word like contains 4 characters which is pair and it should be removed.
So I started writing my program and I am stuck at this block of code -
#include <stdio.h>
#include <stdlib.h>
main () {
char text[100], blank[100];
int c=0,d=0,i,j;
gets(text);
[Code] ....
To explain what is happening - I go through all string and search for first ' ' space symbol and check its value. If it is pair then my program prints that it is not pair[because last character before space had not pair number of characters], but the hardest part comes in when i have two not pair words , because space takes one character and now when i check if i%2 == 1 the answer is false [0] for the second word .
I want the user to enter the word and I want to check if it exists in a text file or not. I tried
int flag=0;
char word[50], input[50];
cout<<"Enter word to search for";
gets(input);
[Code] ....
But it does not seem to be working. Should I make changes to it or is there another way?
I need to compare the words from a text file with words from an array (which i got from another file) and count the instances of those words. I thought about making another array but that doesn't make sense since the text file may have a lot of words in it.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
int main() {
FILE *myFile;
char words[100][40], test;
[code]...
the test variable in the last for loop is wrong i know i was just trying something.
I'm supposed to write a program to read a text file and display the following:
a) alphabetic letters //finished with
b) digits // finished with
c) other characters that are not alphabetic letters and not digits //finished with
d) total characters read
The bold part above confused me, by total characters, does it mean the alphabetic letters + other characters? how would I put that in my code?
Code:
#include <stdio.h>
int main (void)
{
int curCh;
int countCh = 0;
[Code]....
I have to count the letters from a text file into an array so the first spot is the number of A's second spot number of B's and so on then take the array and sort it in decending order how could i do this without loosing track of where the numbers go so if there are more b's than a's they switch but how will i know where each letter has moved in the array after it has been sorted?
View 1 Replies View RelatedI'm trying to make program that will read text from a file and show what words occur how many times. I'm trying to make it so that if a new string comes, it saves it into wlist[], and counts 1 to wcount[]. If the same word is there, it will just add 1 to wcount[]. The program will end when it gets to the end of a file.
I don't know the reason, but I can't get strcmp and strcpy to work. I had to put a pointer in curword, just to make it compile.
Code:
#include <stdio.h>
#include <string.h>
#define LIST_MAX 100
#define WORD_MAX 20

I am trying to read in player names (ex: first last) from a text file into the people[].name data struct. I can successfully read in my card file, but I cannot get this to work. I get a seg fault. I believe this is because nothing is actually being read in for my while loops. I can't use std::strings so these must be c-style strings aka char arrays.
// deck of cards
// below are initializations
#include <iostream>
#include <fstream>
#include <ctime>
#include <stdlib.h>
#include <string>
using namespace std;

const int maxCards = 52;

Write a program that prompts the user for the name of a file. Then it opens the file, and counts the number of words and lines in the file, and prints out those counts.
I think I possibly could somehow use a counter to increment using getLIne() until getLine() returns NULL, but the problem is, I'm worried if I try that, a file that looks like this:
Bla bla bla bla bla lkfdljkfaklafdskjladsjkdfkjlkdfjdfshafdsjkjrerjkkjfaddjkfsafkjdjakdfsjkasfjkjkfdskjldfjkfjkdjfkdsakdjfkjfdkjdfskjfdsk
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjdfkerea
blkjadkjlfdskjldfkjlfdkjfdjkdfsjkldfskljfksfdljfd
Only register four lines and not get the one after the fourth line.
So I was thinking of something like
Code:
#include <iostream>
#include<ifstream>
#include<cstring>
#include<string>
#include<vector>
#include <cstdlib>
using namespace std;
iostream keyboard;
ifstream file;
iostream cin;
[Code] .....
Did I do that right? Will that count the number of words and number of lines correctly?
write a program that counts the number of digits in a file?
For example the file contains:
5 6 7 -8 9obvsefs
6 7 8i uhbnm
8 8
And the program returns: "The number of all digits is 10"
I have this code for a computer project... (store management) but the character strings are not copied on text file..
#include<iostream.h>
#include<conio.h>
#include<fstream.h>
class Store {
public:
char *item_name[5];
store()
[Code] .....
Now when i run the program, it gives a error :::
ERROR
address 0x0
How can i write these strings to the text file?
I have a text file like below read.txt:
1.0 2.0 3.0 4.0
2.0 3.0 4.0 6
5.0 7 1.0 5.0
calc.cpp:
void main() {
FILE *fp;
fp=fopen("read.txt","r");
double *read_feature = new double*[3];
[Code] ....
I want to count all the numbers in my text file (read.txt). Read text file consist of floating and integer number. Answer for the above file would be integer=2 and float =10.
Here is what i have so far:
#include<fstream>
#include<iostream>
#include<string>
[Code].....
I also need to do a loop that scan the count array and check if the element is bigger than the previous one.
I want to input data into text file while not deleting the original data in the file and I use something as
ofstream writefile;
writefile.open("example1.txt");
if (writefile.is_open()) {
for(j=0; j<N; j++) {
[Code] ....
But this will delete the original data.
I wanna read data from txt file with space divided each value like
1.00518 2.01903 3.01139 4.01343 5.02751 5.99913 7.00011 7.99851 8.99506 9.98015 10.9901 11.992 12.9923 13.9932 14.996 16.0034 17.012 18.0255 19.0366 20.0485 21.0505 22.0664 23.0455 24.0383 25.0374 26.0439 27.0378 28.0376 29.0576 30.066
I know the size of the data is 2*500.
In matlab I can use like
fid = fopen('example.txt');
data = fscanf(fid,'%f,',1499500);
how should I write in C++?
I need to copy data from one text file to another.This is how data in file looks like:
2 -3 8 5 0
3 5 1
2 -2 3 1 7 6
5 -3 15 0 1
I succesfully managed to copy those numbers but with one mistake.The last number is written twice. My output file looks like this:
2 -3 8 5 0
3 5 1
2 -2 3 1 7 6
5 -3 15 0 1 1
This is my code:
int a;
string str;
stringstream line;
[Code]....
read some information from a text file. The program I'm working on is like a simple betting program.
What I need to read are:
match_code - team1 - team2 - odd1 - odd0 - odd2
139 Atletico Madrid - Real Madrid 2.853.40 2.35
But the spaces between datas are not known. We only know that both team names may contain more than one word and there is one space, exactly one dash and one more space (" – ") between team names.
Also match_code is an int and odds are double values.
while(getline(input, line)) {
istringstream ss(line);
ss >> match_code >> team1;
string temp;
while(ss >> temp) {
[Code] .....
In that missing part, I need to get the second word of team name if there is one; and the three odds that are odd1 odd0 and odd2.
Each line of the text file has first name, last name, and a salary. Something along the lines of this:
john doe 4000
bob miller 9000
I want my program to take the first name, last name, and salary of each line and assign them to strings. I have tried this so far:
while (inFile){
inFile >> firstName;
inFile >> lastName;
inFile >> grossPay;
cout << firstName << " " << lastName << " " << grossPay << endl;
}
When it outputs the names and the salary, the last line of the text file gets output twice by the program.
Requirements in filtering the text file.
1. first my professor required me NOT to change the MAIN function(because he made it)
2. I have to make 3 getlogs() STRING FUNCTIONS:
a. string getlogs(); - accepts no paramters, SHOWS ALL THE CONTENTS OF TEXT FILE
b. string getLogs(const string & a); - accepts 1 parameter -SHOWS ONLY THE LINE WHICH CONTAINS THE SPECIFIED DATE FROM MAIN FUNCTION which is "2014-08-01"
c. string getLogs(const string & b, const string & c); - accepts 2 parameters, SHOWS ONLY THE LINES FROM THE DATE START to DATE END specified at THE MAIN FUNCTION which is date start-"2014-08-01";DateEnd = "2014-08-10";
3. all COUT should be in the MAIN FUNCTION
TEXTFILE CONTAINS:
2014-08-01 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-02 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-03 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-04 06:13:14,Name,4.5,CustomUnit,CustomType
