Also, if you don't want it to go over 100% if(pages > total) { cout << "Blah blah"; } else {

Also, if you don't want it to go over 100%

Code:

	if(pages > total)
	{
             cout << "Blah blah";
     } else {

I just learned about the if and else if and while if else if and all them loops. lolz.
I could do that, which I will end up making the code more complex, just as a way to test my skills I am learning, but as of the pause, I haven't learned that yet. How would I do that?

system("PAUSE"); works

but

cin.get(); is probably better

Class:

Code:

#include <iostream>

	void DisplayHP();

hehe. probably should have put the combats into classes, but i did this a long time ago. missing some stuff cuz it would be way too long.

EDIT: @the noob on top of me. why the hell would the program close randomly because of int main()? ya sure u aint sleepin in class?

Thats from thatr Guy in youtube. Or its from C++ for Dummies

uhm no its not. those vids and C++ for dummies is bullshit

really cus im taking a Comp sci class and im in the 3rd level of it and if we use int main we get kicked out of class for good.
we must use void main
our teacher is also the same guy who helps IBM Dell and microsoft
but i guess you kno more then him so ok....you win...dont use void main use int main and let your program end for no reason and then wonder y its doing so

if you include conio.h then you can use getch();
to pause it for one char input with out stopping the program for the time

p hasn't been defined, and pages is also not defined. I know HOW to do that, but no matter what, your code there WILL not work, unless you change a couple of things. ;-)

yea i noticed i messed up there a bit so im trying to do it now by doing it in my compiler, at first i just wrote it out in the reply box then as i posted i noticed the errors so im rewriting it now i will post back in a minute
and p was defined in the int calcu as an input (u need to use different names as u pass values thru functions so in main it is pages in the function it is p

I am.

I am determined to learn C++ as a language, so I can make stuff that I can use for ANYTHING.
Not just for hacks.

Now, I know that's what my inspiration WAS to start this determination, but my inspiration changed now.

But ANYWAYS, I figured I would release that code, since it's proof that I AM in fact learning SOMETHING, cuz I wrote that all on my own.

nice i believe in you bro im learning it also so we can help each other i have actually made on hack but im trying to get it so it can not dc

what compiler are you usen.
the one im usen wont let me use system("PAUSE");
ever but im usen turbo c++ 3.0 IDE

also i did this but the funtion still returns nothing

all tho its the same structure as i use in all my programs
but im tired its Saturday and i dont want to think to much so i give up on trying it but thats the way i was taught to code by my teacher at school

Code:

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

int calcucpp(int p,int CPP){
    int temp;
    temp = p/CPP;
    temp = temp * 100;
    return temp;
}

void main(){
    clrscr();
    double CppPrimer = 1225;
    double total = 2501;
    int pages;

    double temp;

    cout<<"Enter the total amount of pages read so far : \n\n";
    cin>>pages;

    cout <<"% of CppPrimer "<<calcucpp(pages,CppPrimer)<<endl;

    cout <<"% of total pages "<<pages/total * 100<<endl;
    getch();
}#include <iostream.h>
#include <conio.h>
#include <math.h>
const int CppPrimer = 1225;
const int total = 2501;

int calcuCPPP(int p){
    int temp;
    temp=(p/CppPrimer)*100;
    return(temp);
}
int calcutotal(int p){
    int temp;
    temp = (p/total)*100;
    return(temp);
}

void main(){
    int pages;

    cout<<"Enter the total amount of pages that you've read so far:\n";
    cin>>pages;
    cout<<endl;

    cout<<"Percentage outta the C++ Primer Plus: 5th Edition: "<<calcuCPPP(pages)<<"%"<<endl;
    cout<<"Percentage outta all the books: "<<calcutotal(pages)<<"%"<<endl;
    getch();
}

hey dick can it

the return 0; he was missing would crash if he had a longer program ive done it before and ended up losing the work.

if you have

Code:

int main(){
//lots of code here
}

then it can crash

but

Code:

int main(){
cout<<"Hey";
}

theres no need for it cus the program ends before theres a chance for it to lose the track of main

as for

Code:

void main(){
//code here
}

its not trying to return or look for the return of the value of main
so it wouldnt have an issue at all
if you would get your head out of the books telling you the wrong information and learn the RIGHT way you would see this.

that version of c++ is dulled down for the easy of use

if you use an older compiler it will make it alot harder to get errors fixed and make you really learn the syntax of c++ so you dont make errors as much

vc++ pretty much tells you exactly where the error is

my compiler will tell you the line and the error not that your missing a ";" at line 12 col 33
but "unexpected end of line at line 12"
