C++ :: How To Read A Sentence From A File
Dec 28, 2014
So I'm working on that program that uses .txt files to store data, and I have one problem: I can't recover one full name from the .txt file
It's a school library program and it uses the <fstream> library for file operations, it stores theBookSignature >> theNameOfTheAuthor >> theBooksName.
I understand that C++ stops the input of a line when it stumbles upon a space, but isn't there something like a getline(cin, variableName) for file streams?

I wrote this program:
#include <iostream>
#include <ctime>
#include <ctype.h>
#include <vector>
#include <string>
#include <sstream>
using namespace std;
[Code] ....
LETTER OR '.' ? s
LETTER OR '.' ? f
LETTER OR '.' ? b
LETTER OR '.' ? e
LETTER OR '.' ? a
LETTER OR '.' ? g
LETTER OR '.' ? .
VECTOR : [ SFBEAG ]
SENTENCE ?
But after this i can't write anything. Do you know why? I've never had problems with getline... when i used cin >> it read but only one word. Now it doesn't even let read...

I am trying to write a program that ask the user to enter a sentence and then a word to be searched for in the sentence. The program must then search for the word in the sentence in a loop and continue to output each place the word is found. For example if the sentence is : I like pickles, pickles, pickles
and you searched for pickles it would return pickles found at 7, pickles found at 16, pickles found at 25.
I am having trouble writing the equation to make the find keep searching after each occurrence of the word being searched. Here is the code I have so far
HTML Code:
#include <iostream>
#include <string>
using namespace std;
int main() {
string paragraph;

I've created a class that is supposed to store first name, last name, date of birth, date of death, and a fact about a person (all variables within the class). Im trying to fill these variables with a read function. it reads a .txt file like this
Firstname Lastname 1987 1988 this guy did this
The problem is, I don't know how to handle the last variable. the variable needs to hold the entire "this guy did this" sentence. i made it a string, just because i was clueless, and as expected, it only holds "this"
this is my .h:
#include <string>
#include <fstream>
#include <iostream>
using namespace std;
class Person {
public:
Person();
Person(const Person & person);
[Code] ....
Here is the read function in the .cpp:
bool Person::Read(ifstream & input) {
return (input >> fname >> lname >> dob >> dod >> fact);
}

I thought maybe there was something in C that could read full sentences from stdin
Code:
scanf("%100[^
]s", string);
But that's not working for me. so i came up with my own function and its not giving me the results i want. here is the function including the call from main:
Code:
/* * * * * * * * * * * * * *
* FROM MAIN *
* * * * * * * * * * * * * */
printf("
Adding a new part...
");
printf("Enter part name: ");
get_string(new_part.pname);
[Code] .....
/* * * * * * * * * * * * * * * * * * * * * * *
* UNDESIRED OUTPUT *
* * * * * * * * * * * * * * * * * * * * * * */
8newpart
Where is the eight coming from? i thought fpurge clear the buffer. Also, I'm trying to add spaces in between words... i thought maybe putting within the while loop but outside of the if statement string[length +1] = '' would work, but it doesn't. so i put it outside of the loop but that i knew that wouldnt work either.
Problem #2 is reading from a file.. so far i have the following code which reads everything perfectly except the .txt file has a new line character at the end and i think its reading it:
Code:
/* * * * * * * * * * * * * * * * *
* READS FROM FILE *
* * * * * * * * * * * * * * * * */
if(read_in != NULL)
{
while ((fgets(read_string, MAX_PARTS ,read_in) != NULL) && (array_position < MAX_PARTS))
[Code] ....
0 in stock i want it to stop after reading the ball bearings line. a lot of issues for one post, but all related to reading inputs so i put it all on one.

I 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?

So I'm trying to reformat a paragraph where the first letter of each sentence is capitalized and the rest are lower case. This is my function thus far. I'm trying to read for the end marks . ! and ? and have it so that once the are encountered the next word is capitalized. I used ispunct initially but it read for things like ,'s as well.
int PunctCount(string Text)
//Counts the end marks. {
int Total = 0;
for (int i = 0; i < Text.length(); i++)
if (Text == '.' || Text == '?' || Text == '!')
Total++;
return Total;
}
Right now I get error: no match for âoperator==â in âText == '!'â

My program will ask the user to enter the number of lines for the sentence "I will always use object Oriented programming. " if for example, the user enters 3, it should print out
I will always use object Oriented programming. I will always use object Oriented programming. I will always use object Oriented programming.
the second part of my program asks the user to enter the line which we want to make a typo. If they enter 2, it will replace the "I will always use object Oriented programming. " with "I will always use object Oriented programing." in the second line.
this is how it should look like but I am having trouble putting the second part together. I don't know how to remove the sentence and replace it with the second part.
Enter the number of lines for the punishment: 6
Enter the line for which we want to make a typo: 3
I will always use object oriented programming. I will always use object oriented programming. I will always use object oriented programing. I will always use object oriented programming. I will always use object oriented programming. I will always use object oriented programming.

The Objective Of This Program Is To Create A File To Write Text And Read Back The File Content. To Do That I Have Made Two Function writeFile() To Write And readFile() To Read.The readFile() function works just fine but writeFile() doesn't.
How writeFile() function Works? when writeFile() function Execute It Takes Characters User Type And When Hit Enter(ASC|| 10) It Ask "More?(Y/N)" That Means What User Want? Want To Go Next Line Or End Input?
If "Y" Than Inputs Are Taken From Next Line Else Input Ends.
But The Problem Is When Program Encounters ch==10 It Shows "More?(Y/N)" And Takes Input In cmd variable.If cmd=='Y' I Mean More From Next Line Than It Should Execute Scanf Again To Take ch I Mean User Input.But Its Not!!! Its Always Showing "More?(Y/N)" Again And Again Like A Loop.
Code:
#include <stdio.h>
void writeFile(void);
void readFile(void);
int main(){

I am writing a simple file/text parser to read a config file for some code I am working on. It's dead simple and not particularly smart but it should get the job done. The code reads a config file:
Code:
readlength=2500000
start=0
finish=25000000
cutoff=20000
samplingfreq=250000
poles=10
filterpadding=500
}
[code]....
Here is where it gets wierd. You'll notice that there is an unused variable (filepath) in the config struct. This variable is not referenced or used anywhere in the code, ever. Yet if I comment out the declaration of char filepath[1024], the code segfaults partway through the read_config() function.
My best guess is that there is a buffer overflow elsewhere and it just so happens that the memory allocated for filepath happened to be there to catch it up until now, but I can't work out where it might be happening. With the declaration commented out, the read_config() function gets as far as reading the "padding" variable before it crashes. Yet when the declaration is there, then all the variabled are read correctly and everything seems to work.

Im writing a c program that reverses the words in a sentence,
Example:
you can cage a swallow can't you?
you can't swallow a cage can you?
I have it all working, except the fact that I dont know how to get the words themselves to turn around. Heres my code and an example of the output im getting.
Output Im getting:
Enter a sentence: you can cage a swallow can't you?
Reverse of sentence: uoy t'nac wollaws a egac nac uoy?
Code:
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#define MAX 200 /*Decent number of chars for a sentence*/

Write a program that calculates statistics on word length for a sentence. The sentence isterminated by a ',' For each found length of a word the number of words of that length is printed. Only those lengths that are found in the input are printed. Only letters from a-z or A-Z are allowed to form words. Words are separated by a space. No punctuation characters other than ',' are allowed. If any other input character is recognized or the input is longer than 80 characters the program displays "NOT VALID" (see Hints).
Note, that in the case that no word is present in the input, nothing is printed.
% u6_stats
Enter a sentence: Bolt was expected to use the super bark.
Length 2: 1
Length 3: 3
Length 4: 2
Length 5: 1
Length 8: 1
% u6_stats
Enter a sentence: Something wasn't right.
NOT VALID
Thats what i've already done.
Code:
#include <stdio.h>
#include <conio.h>
void main() {
char s[100];
int numOfWords, lengthOfWord = 0;
[Code] ....
So, the problem is that if i inpute a text like"abc abcd abc abc" the result will be like
"length 3: 3 length 4: 1 length 3: 2".
So when the program already compared 1st (here 3) element with others, this element will not be comparing again, but i have the 3d element with same length, and it that case, the program compare it with remained elements and print 2. How can i rework my code, if i don't wont to compare already compared elements.
Second problem is that i need to get results from lowest length till highest.

I want to count all the vowels in a string (a, e, i , o, u) and display it as a text-based histogram for example:
[INPUT] The black cat sat up on the orange mat!
[OUTPUT]
A: *****
E: ***
I:
O: **
U: *
The asterisks are supposed to correspond to the number of vowels that are counted (using increments and the function setfill()).
#include <iostream>
#include <string>
#include <iomanip>

This is my output during compilation:
[OUTPUT]
The black cat sat up on the orange mat! 0 0 0 0 0

Write a function that accepts a pointer to a C-String as an argument and capitalizes the first character of each sentence in the string. For instance, if the string argument is "hello. my name is Joe. what is your name?" the function should manipulate the string so it contains "Hello. My name is Joe. What is your name?" Demonstrate the function in a program that asks the user to input a string and then passes it to the function. The modified string should be displayed on screen. Optional Exercise: Write an overloaded version of this function that accepts a string class object as its argument.
#include<iostream>
#include<cctype>
#include<cstdlib>
using namespace std;
void capitalize(char sentence[], int const SIZE);
[Code]...
Not even sure if I'm headed in the correct direction, but I'm getting the following errors:
E:CPT-233Sentence Capitalizer.cpp In function `void capitalize(char*, int)':
34 E:CPT-233Sentence Capitalizer.cpp call of overloaded `strstr(char&, const char[2])' is ambiguous
note E:CPT-233<internal>:0 candidates are: char* std::strstr(const char*, const char*) <near match>
note E:CPT-233<internal>:0 char* std::strstr(char*, const char*) <near match>

I have been trying to get this to work for a while now - with no success.
Basically I am trying to write a function which the returns the first word of each input sentence in a single string - this is part of a larger cryptography program I am working on.
So for example, if this string was passed into the function:
"This is what I mean. Is it right? A poor puppy abandoned. Secret torturing of dogs are happening. Message: be on the watch."
It should return:
//declared in class "steganalyse"
string cyphertext;
string punctuation = ".?!;:'";
book is_first_word
[Code] .....
But this only returns the first word:
This
Any other way to return the first word of each sentence in a string.

I'm not sure what the program's purpose is?
1) Ask the user to enter a sentence. Until you reach the end of the sentence, test each character to count the number of spaces and letters.
2) For every space counted, print "SPACE", then print one "!" for every letter counted on an indented line underneath the "SPACE".
Your test sentence to use is: "The potash feldspars are important rock-forming minerals in plutonic, volcanic, and metamorphic rocks."
HINT: You do not need any strings. You need one while loop and two for loops. <cctype>
