C/C++ :: Can't Read In String From Text File
Feb 17, 2014I'm trying to make a program that will read in names and grades from a text file and print them in the console. However whenever I try to use the OpenFile.get function I get an error saying that there is "no instance of overloaded function"

C++ :: Read A String Of Unknown Length From Stdin
Oct 10, 2014I want to read a string of unknown length from stdin. I tried to follow the approach from this link. URL....My code is like this:
#include <iostream>
#include <string>
using namespace std;
int n;
cin >> n;
cout << "The value of n is " << n << endl;
}
[code]......
What I have noticed is that if I take integer input from cin (cin >> n;) in the above code before getline, the control does not stop on getline to take str as input from the console. If I don't do (cin >> n) before getline then the control stops on getline and takes the string as input.What is the best way to read from console multiple strings of unknown length in combination with the integers?
C++ :: How To Read All Content From A Text File Into A String
Sep 24, 2013I'm trying to read all content from a text file into a string. This is the code I'm using for it (I know there are other, maybe better ways to do it but I'd like to stick to this for now):
char* buffer;
std::string data;
FILE* fp = fopen("textfile.txt", "rb");
if (!fp) {
printf("Can't open file");
[Code] ....
So my problem is that I get an exception when I try to free the memory -> 0xC0000005: Access violation reading location 0x51366199
I even get the exception when I try to free it immediately after calloc() but why this is.
And if I use buffer = (char*)malloc(lSize); I don't get any exceptions.
So, why this fails and what I'm doing wrong.

C Sharp :: How To Read And Split File As String
Apr 16, 2013how to do this in C#. Need to connect to Oracle db, take a file from directory then read every line of the file. Lines are like this:
123234847656|8800359898818177|A|20130401 14:51:42|
123234847212||D|20130401 14:52:08|
123234847212||M|20130401 14:55:38|
Then will split as string on every '|' char and according to this flag |A|, |D| or |M| I will add/delete/modify information inside. I have trouble with this part with the connection and read/split file and check for the flag A, D or M.

I haven't done any programming in C before and I don't know how to handle strings and characters in C.
C++ :: 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.
