array problems Hello boys and girls,
I'm wondering around with arrays and I'm trying to get one up so that it grabs a user inputt'd char and adds it on then prints out the contents of the array so far
ie "Enter character" :
User enters : 'A'
Prints out A on screen
"Enter character" :
User enters B
Printsout A and B on screen.
I've got no problem populating and printing out arrays, but I cant figure this one out.
I've thought adding to strings but no luck there.
I've got this so far but it doesnt help at all and I know why but not sure how to defeat this...
[code]
...
int i;
for (i = 0 ; 1 < 5 ; i++)
{
cin >> buffer[i];
}
for (i = 0 ; i < 5; i++)
{
cout << buffer[i]
}
whilst this code doesnt do what ask'd
I thought'd about how to get one step closer:
for (i = 0 ; 1 < 5 ; i++)
{
cin >> buffer[i];
{
for (i = 0 ; i < 5; i++)
{
cout << buffer[i]
}
}
}
but still fails....can anyone help us out here?

what do you mean "it failes"? it won't compile? it won't run? what error(s) do you get? Note: unless its just a posting error, it needs a semicolor at the end of the cout line. Also, how is buffer declared?

i tried this and it worked fine
#include<iostream.h>
int main()
{
char buffer[5][10];
for (int i = 0 ; i < 5 ; i++)
{
cin >> buffer[i];
}
for (i = 0 ; i < 5; i++)
{
cout << buffer[i];
}
return 0;
}
#include<iostream.h>
int main()
{
char buffer[5][10];
for (int i = 0 ; i < 5 ; i++)
{
cin >> buffer[i];
}
for (i = 0 ; i < 5; i++)
{
cout << buffer[i];
}
return 0;
}

did you try this
char buffer[6]; for(int i = 0; i < 5; i++) cin >> buffer[i]; buffer[5] = 0; cout << buffer << endl;

Sorry to put a downer on things but I've built these, the next objective was to create something like this:
user enters A
konsole windows prints A
user enters B
konsolewindow prints AB

By "user enters A" what exactly do you mean? one character? a whole string of characters? a number?
std::string buffer[5];
for(int i = 0; i < 5; i++)
{
cout << "Enter string #" << i+1;
getline(cin,buffer[i]);

Re: array problems i guess this will solve your problem
#include<iostream>
using namespace std;
int main()
{
char buffer[6];
for(int i=0;i<6;i++)
{
cin>>buffer[i];
for(int j=0;j<=i;j++)
cout<<buffer[j];
}
return 0;
}
#include<iostream>
using namespace std;
int main()
{
char buffer[6];
for(int i=0;i<6;i++)
{
cin>>buffer[i];
for(int j=0;j<=i;j++)
cout<<buffer[j];
}
return 0;
}

yes thats the one!
man a simple code seem'd so hard to do, thanks back to my game now....
why does it not register the first char input?
