int main() { cin >> words; output = "";

>>58724645
never mind the cout at the end, I already fixed that to output.

>>58724645
the error is on the line output += ... and pertains to words.at[i] I presume

>>58724645
Wow, that's embarrassing

>>58724645
>isn't a string inherently an array of characters

Yes, but C++ (correctly) tries to hide this from you. Something like words.c_str()[i] might work.

>>58724887
It runs with that but it doesn't print anything

>>58724645
Yes but a function is not an array of characters.

>>58724927
and debugging didn't give me any valuable insight

>>58724927
Probably because you're exiting your for and while loops immediately by putting a semicolon before the loop body

>>58724927
>>58725050

Explain to us exactly what your code is doing here (hint: your error is there):

for (i = 0; i < size; ++i); {
    while (i < size); {
    output += (":regional_indicator_" + words.at[i] +':');
    }                
}

>>58724645

 words.at 

is a function. You're trying to index a fucking function.

words[i]
//or alternatively
words.at(i)

Your fucking loops end with a semicolon;

for (i = 0; i < size; ++i)/*----->*/; // <--- see this little nigger?
while (i < size) /*----->*/; // <--- he's fucking your shit up

for and while execute the statement or block that follows it. Statements are delimited with a semicolon. Your code basically does this.

for (i = 0; i < size; ++i)
    ;
{
    while(i < size)
        ;
    {
        output += (":regional_indicator_" + words.at[i] +':');
    }
}

Fucking remove those shitstain semicolons.

Now fuck off with your shitty bait.

Only two anons have stated the blatant problem of this code, fuck neo-/g/.

>>58725136
Thanks. I took out the trouble semi colons. Now when the program is ran and text is entered, it creates a new line and does not close. After a minute it's using 356 MB of my memory...

>>58725136
and sadly this isn't bait. this is the extent of my coding prowess from what I can remember of the programming class I took 4 years ago.

what do you think this does:

  while (i < size) {
    output += (":regional_indicator_" + words.at[i] +':');
  } 

#include "stdafx.h"
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;

string output;
string words;
int i;

int main()
{
        cin >> words;
        output = "";
        int size = words.size();
        for (i = 0; i < size; ++i) {
            while (i < size) {
                    output += (":regional_indicator_" + words.c_str()[i] +':');
                }                
            }

        cout << output << endl;
    return 0;
}

This is where I'm at now. Takes input text then goes into some sort of memory hogging loop and doesn't print the output.

>>58724645
That is some spaghetti code.

>>58725515
From what I'm seeing you need to take a step back and start at square one, anon. Relearn for and while loops and how they're structured.

>>58725508
adds each character in a string to output plus the string of text and char.

>>58725544
Yeah, the second line does the concatenation as you say. But what about the first and last lines, do you really need this block surrounding it? If yes, why?

>>58725515
The while loop will run forever as there is no chance for the i to get an increasement. Remove it

>>58725084
This

This is a sad thread

>>58725515
If as I think you want to display each word of your input with a prefix, you should rather the standard 'std::split' method to get a word array, then use a loop (use a standard iterator if you feel brave enough)

>>58725709
negative, each letter.

#include "stdafx.h"
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;

string output;
string words;
int i;

int main()
{
        cin >> words; // gets words from user
        output = ""; // readys the output string
        i = 0;      // warms up the calculator
        int size = words.size();  // size matters
        while (i <= size; ++i) { // loops through each character in "words" (can't increment in the function?)
                    output += ":regional_indicator_" + words.c_str()[i] +':'; // appends output with each letter from words plus a suffix and prefix
                }                

        cout << output << endl; // prints the ouput
    return 0;
}

Where did it all go so wrong?

>>58724645
Get rid of the while loop (also the while loop has nothing inside of it because of your ;
If you want to get the character that the i position of words just do words[i].

>>58725949
I took the ; out of the while loop function and added && + i to the code of the loop.
Now the console gives me

hello world
[6 blank square characters]
Press any key to continue . . .

>>58724645

>stray semicolon strikes again

OH MY GOD

>>58725205
I count 3 before you and two more calling OP an idiot.

Now when I input "hello world" it outputs "osss" ...

>>58726717
did I accidentally create a new open-source encryption algorithm?

>>58724645
what the fuck are you even trying to accomplish with that nested loop ?

>>58724645
IF this isn't bait, just quit now.
There is no hope for you, if you are this unaware or stupid.

>>58726887
it seems a lot of people here were born knowing C++ syntax. What is your nationality?

pls help im so confused
