prompt for pressing "enter"

[jagerhans]

I need to stop the output till one presses the <ENTER> key.
well , with BASIC I used to do this:
DO WHILE INKEY$ = ""
LOOP
with c++ , under DOS one could use
#include <stdlib.h>
#include <stdio.h>
int main()
{
system ("pause");
return 0;
}
but since I switched to Linux (and Kdevelop) all the old stuff is of no use.

another question: when I put a prompt with the cin >> something ; function how can I trap errors (eg a charachter instead of an int) ?

You could take everything as an array of characters and then on each check each character

bool CheckForInt(char[10])
{
for(int i=10; i<10; i++)
{
if ((int(char[i])<58)&&(int(char[i])>47)){return TRUE;}

return FALSE;
}
}


assuming you aren't going above ten digits

numeric chars are between the values 48-57

I guess you'd probably call that function in a do while condition the encloses the input promting so that it continually prompts until the user puts in a integer value

Somehow you'd have to convert it back to a number though.

There's probably a better way to do it.
