C/C++ :: Getline Not Allowing To Read A Sentence
Apr 15, 2014
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...

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?

Having an issue with the following code. I read in a decimal value from a text file, use atof (or strtod, either gives the same error) to convert the read value into a floating point number. When putting the output of atof in a double, it works fine. However when putting the output of atof into a float, the decimal places get lost. Putting the result in a double, then into a float gives the same result. This only happens when using getline.
I've tried using temp arrays to put the result of pch in, sprintfs and such to try and work around it, but whenever a value originates from the getline command, the float value always loses decimal places. I've also tried varying the precision in the printf statement, but its always the same. When I write the float result to a file via FILE.write in binary mode, the result comes out without the decimal places when I read it back in later.
The simple solution is to not use float and use double, but there are a number of reasons I'm using float to begin with and don't want to change that.
Side note, this code works fine on a windows machine, the error is coming from using g++ on a mac.
Code:
printf("Reading from File
");
ifstream FILE(argv[2],ios::in);
char BU[128];
char *pch;
[Code] ....
Code output :
Reading from File
338769.0109
338769.010900
338769.000000

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;
[Code] ....

I've written a program that finds the maximum of a function. I now want to change it a little so that instead of evaluating the function y=x^2-7x-18, the program will ask the user to input an equation and then evaluate that equation. I'm really not sure of how to do so.
#include <iostream>
#include <cmath>
#include <cstdlib>
using namespace std;
int main() {
int a, b, delta, x, y;
double max= -1.8 * pow(10, 308);

This code is near complete, the only task that is left is allowing the user to input a decimal and then two integers, or automatically using .00 decimal.
The automatic part: /*This is not correct.
printf(".%.2d
", number);
*/
But that does no good for me. Question: Do I have to create a some sort of while loop again, to allow the user to input a decimal followed by integer?
Code:
#include <iostream>
#include <cstdlib>
using namespace std;
int main() {
int j , i = 0, k = 0;
int number;

I've been writing some code and this is part of it:
Code:
...
URLDownloadToFile(NULL, _T("http://something/something.txt"), path, 0, NULL);
return 0;
}
The file gets downloaded successfully but the downloader wont exit (return value 0). So it remains active.
I am sure the problem is URLDownloadToFile()
I am using Visual Studio 2010 Express.

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

I've just started learning from "Jumping into C++". Great book. Unfortunately, I've also encountered my first snag. Practice problem number 3 from chapter 4 tells me to make a small calculator that takes one of the four arithmetic operations and its two arguments as input and give the result as output. Here's what my newbie mind came up with:
Code:
#include <iostream>
#include <string>
using namespace std;
int main()
[Code] .....
The thing that I don't get is why doesn't the function "getline" work. It's worked in previous programs. The program seems to work if I simply replace getline with a simple "cin". I could easily use that as a cheap fix but I am interested in knowing why "getline" refuses to work anymore....

I'm currently trying to write a while loop that checks if the text file has read all the contents inside. I've tried using
while(!in.eof())
but as usual it executes my loop an extra iteration, printing my last output twice. I am reading my data in from a method inside a class, so I cannot use getline as my while test to check if the file has read input or not. Is there any way to force my loop to check if the end of file has been read before the eof() test is executed?

I am just trying to get a code going for a mock test and to get use to the getline and IF operations, but it seems I have ran into an issue[URL] is a link to the code I have written, and I can use getline to give a value to my variable, but it seems like it gets lost once I try to use the IF function. Am I not using the right variable type?

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.

I have to write a program to reverse a sentence like
cat

I have just started working through "Jumping into C++". I am at the section on appending strings. The tutorial mentions the getline function but I can not seem to get it to activate. There is no mention of any other inclusions.
Code:
#include <iostream>
#include <string>
using namespace std;
[Code] ....
I note that the getline function color remains black while other functions are green. I presume this means that Codeblocks has not associated it with any of the listed header files. Has the tutorial omitted this detail?

How the getline function works.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main() {
[Code] ......
getline(&inputstr, 128, NULL); getline gets a line in a data file.
I assume that inputstr[128] is the name of the file? why is the number of the array in the getline function....

why does this happen that if i use
string ans;
for(int i=1; i<3; i++)
{
cout << "enter an option" << endl;
getline(cin,ans)
}
in a loop it always skips the first time but in the next times it asks?

I am trying to use getline as the conditional for a while loop as seen below.
string filename, guard_name;
int call_number;
vector <Seniority> SeniorityList;
ifstream SeniorityFile;
[Code] ....
However, when I compile the code, I get the following error message on the line with the while loop.
error C2780: 'std::basic_istream<_Elem,_Traits>
&std::getline(std::basic_istream<_Elem,_Traits>
&,std::basic_string<_Elem,_Traits,_Alloc>
&)' : expects 2 arguments - 3 provided
The program will be reading in a .csv file, so I need my program to be able to deal with values separated by commas. Is there a reason why it will not accept that conditional statement?

I used getline to import EMPLOYEE's First and Last Name from a txt file. After calculating the weights ans stuff. Now when i try to write to output txt file am having the below issue in which its not putting it in one line.
***CODE***
fout << "Note: This report for " << employee << " was prepared according to the fair practice of the University." << endl ;
***THIS IS WHAT ITS PRINTING***
Note: This report for FIRSTNAME LASTNAME was prepared according to the fair practice of the University.
I also tried like this;
***CODE***
fout << "Note: This report for " << getline(fin, employee) <<" was prepared according to the fair practice of the University." << endl ;
***THIS IS WHAT ITS PRINTING***
Note: This report for 0 was prepared according to the fair practice of the University.
this second code puts everything in one line but its showing 0 (zero) instead of the employee's first and last name.
