Hello, I am trying to figure out a way to remove whitespace inside a string. Can anyone help me a little on this.
Example: input:ha ha ha
output:hahaha

I manage to only remove one space inside a string
like: input:ha ha ha
output:hahaha
Following are the code I have gotten so far:
#include <iostream>
#include <string>
using namespace std;


int main()
{
string input;
int i = 0;
int space_appearance = 0;

getline(cin, input, '\n');

for(i = input.find(" ", 0); i !=(int)string::npos; i=input.find(" ", i))
{
input.erase(i, 1);
space_appearance++;
i++;
}


cout << input << endl;
cout << space_appearance << endl;
}



I would really appreciate for anyhelp, thank you very much!

hi
its working code. for input a b c d
i got output abcd 3

Is this homework?

"_" denotes spaces for easy reading
input:ha_ha_ha
output:hahaha correct

input:ha_ha__ha
output:haha_ha incorrect

input:__ha_ha_ha
output:_hahaha incorrect

As you can hopfully see from the output you are not far away from getting what you want but there is a logical error here. Can you see what it is?

As a side note please include "return 0;" at the end of your main func as it should return an int.

<edit> maybe '_' wasnt the best char to use to show the error, does this make it clearer.
'/' denotes space
input:ha/ha/ha
output:hahaha correct

input:ha/ha//ha
output:haha/ha incorrect

input:////ha/ha/ha
output://hahaha incorrect

dmail, I see the logical error here. The loop only interate the string once, and it only delete one character at a time. I was stuck on this as well, had a hard time to get over wtih it.
I am able to correctly delete whitespace in front and after the string, but not inside the string.

haha dmail!!!
I got it
stupid "i++"!!!!!
thank you for your hints.!!

Well done. I didnt want to just give you the answer.
