error

[4jzvC542]

I am trying to compile this program but it is showing errors
I am using Microsoft Visual Studio 2006 standard edition.
This is my source code:


-------------------------------------------------
#include <iostream>
#include <conio.h>

using namespace std;

void main()
{
int ch;
int chcnt = 0;
int wdcnt = 1;

while ((ch = getche()) != "\r")
{
if (ch == " ")
wdcnt++;
else
chcnt++;
}
std::cout << "No of Character Entered : " << chcnt << "\n";
std::cout << "No of Words Entered : " << wdcnt << "\n";
}
----------------------------------------------------------------


On compiling it shows this error :

Firstly ch should be a char and not an integer...
You should consider replacing the double quotation mark with a single one (ie: instead of "\r" use '\r' -- line 11 and instead of " " use ' ' -- line 13).
However, I also recommend moving the assignment from line 11 ch = getche() to, let's say, line 10.

Hope it helps.


Kind regards,

i think getch() or getche() are returning nothing(these are void functions)

[AbstractionAnon]

No, they are int functions, not void functions.
They return the keycode read.
