help again please

c:\documents and settings\owner\my documents\lessons\untitled1.cpp: In function `int main()':
c:\documents and settings\owner\my documents\lessons\untitled1.cpp:5: parse error before `<'
c:\documents and settings\owner\my documents\lessons\untitled1.cpp:6: parse error before `:'

#include <iostream.h>
int main ()
{
int thisisanumber
cout <<"please enter a number; " ;
cin >>thisisanumber :
Cout<< "you entered: " <<thisisanumber;
return 0;
}




what is the problem with this code?

Start by changing

int thisisanumber

to

int thisisanumber;

Cout<< "you entered: " <<thisisanumber;

to

cout<< "you entered: " <<thisisanumber; (maybe not sure if it's case-sensitive)

cin >>thisisanumber :

to

cin >>thisisanumber ;

You forgot a ; after your int declaration and you used a : instead of a ; after your cin statement.

Gretchen

#include <iostream.h>
int main () {
int thisisanumber;
cout <<"please enter a number";
cin >> thisisanumber;
cout <<"you entered: " <<thisisanumber;
getch();
return 0;
}

this should work.

actually, getch() is in conio.h

C++ _IS_ case sensitive.

For people who do not know what case sensitivity is-
means joe can be made into 7 different variables by using different case's-

JOE
JoE
Joe
JOe
jOe
jOE
joE

O yeah, forgot about conio.h header :P

thanks for pointing me with this.

Come on -- powers of 2! Not 7 possibilities, it's 8!

There's 3 letters each with 2 possibilities. That's 2^3 which is 8 different possibilities, not 7.

As a programmer, just look at it as a 3 digit binary number. 3 binary digits can represent 8 different values.

In case you're wondering, the one you missed was joe (all lowercase).

Wow, you're really something else, Poly. 'Just think of it as binary.' Yeah, like that'll help the newbies remember how to calculate statistics:rolleyes: ;)

lol...the newbies can ignore it though. they'll eventually learn it.:)

The first thing I learned before C++ was binary. Isn't that sort of standard? I learned binary, octal and hex before doing any coding.

getch() is a non-standard function. Its good coding practice to avoid non-standard functions.

I believe that you wanted the output screen to just PAUSE at the end of the execution, why don't you try

system("give the OS command that is used to pause within this quote");

// stdlib.h is the headerfile for system


you could even have a dummy input statement instead

I wonder how "Polymorphic OOP" missed this ????

Sorry, math is not my strongest point. LOL. Thanks for correcting me.

actually the dummy input statement is a good idea. but the system calls are OS dependent.

poly, I haven't really learned much, I know some binary, the idea of powers of two, and 0 is false and 1 is true. maybe because i'm still in high school. I probably will in college, learn binary, hex, etc. and technically, i would say, i'm still a newbie.
