Hello,

Say I have a file with two lines:

// file
20 21

//end of file

How do I get the numbers into integer variables from the file in an efficient way?

Hi,

Is there a way to output data to a file without erasing its contents?

Thanks

Neil

Its only caps.

so for example i need to sort the string "TEST" to "ESTT".

Do you have some code? I'm lazy ;)

Hello,

Does anyone have an algorithm or know a function that can sort a std::string for me?

Say i have:

string one = "test";

sorting it alfabetically would result in > "estt"

Thanks Lindley!

Sure, here's the code. Its a program that reads a file. The first to lines are int, first int states how many rows there are after the 2 lines that have been read. The second int says how much colums...

Thanks for your reply, I understand. Would using a std::string in this case be more efficient (as in faster to make)?

Hi,

Is it possible to delete certain items from a char sequence or string?
Say i have:

char test[5] = {'a','b','c','d','e'};

Is it possible to delete 'a' for example?

Thanks!

Thank you, Lindley. That helped!

@ Philip, is there a way i can read it directly into int?

Thanks for your quick reply, i get an error whilst compiling though.

Heres my code:
<code>

#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
using namespace std;
