Need help with a C++ program I'm creating. I thought it would be easy but it's not.?

What is the problem in the following, I cannot run it because it has 17 erros..?????????





/*************************************...


Radius of a circle


This program calculates the radius of a cirle


**************************************...


#include %26lt;iostream%26gt;





using namespace std;





const float PI = 3.141593





int main()


{





float numbera;


float numberb;


float numberc;


float sum;


float radius;


cout %26lt;%26lt; "Enter an integer or a decimal number: ";


cin %26gt;%26gt; numbera;





cout %26lt;%26lt; "Enter a second integer or a decimal number: ";


cin %26gt;%26gt; numberb;





cout %26lt;%26lt; "Enter a third integer or a decimal number: ";


cin %26gt;%26gt; numberc;





sum = numbera + numberb + numberc;


radius = float(sum)/2 * PI;


cout %26lt;%26lt; "The radius is " %26lt;%26lt; radius %26lt;%26lt; endl;





return 0;


}

1.Multi line comments (as you have placed at the top) start with /* and end with */ .


2.Put a semi-colon ( ; ) after the statement:


const float PI = 3.141593


3.You are using the latest ANSI C++ IDE. So, you have to include std: before the cout and cin objects.





The correct program will look something like this:








/* __________ __Your comments_ _________


______here_______ ______ */


#include %26lt;iostream%26gt;





using namespace std;





const float PI = 3.141593;





int main()


{





float numbera;


float numberb;


float numberc;


float sum;


float radius;


std:cout %26lt;%26lt; "Enter an integer or a decimal number: ";


std:cin %26gt;%26gt; numbera;





std:cout %26lt;%26lt; "Enter a second integer or a decimal number: ";


std:cin %26gt;%26gt; numberb;





std:cout %26lt;%26lt; "Enter a third integer or a decimal number: ";


std:cin %26gt;%26gt; numberc;





sum = numbera + numberb + numberc;


radius = (sum/2) * PI;


std:cout %26lt;%26lt; "The radius is " %26lt;%26lt; radius %26lt;%26lt; endl;





return 0;


}





If the const statement doesn't work, just define Pi like this:


#define PI 3.141593


and place it just below the #include %26lt;iostream%26gt; line.

Reply:Don't pay too much attention to the number of errors reported by a compiler. Once they get confused, they tend to stay confused for a bit.





You have a comment which is unterminated. You are missing a semicolon at the end of a statement. These are likely the only two errors you have. I'll let you hunt a bit, rather than giving you the exact answer, as you will need to learn to track these things down.
Reply:u forgot sum semi-colons, getch();





im in ninth grade i took c++ for 1 semister, its over now
Reply:radius = float(sum)/2 * PI;





A while since i've done C++ but i really dont think u should put "float" on that statement.
Reply:#include %26lt;iostream.h%26gt;





dont forget the .h at the end
