My first program! Is it correct? My school's c++ software is still being configured.

[fallen_warrior]

Here it is...

#include <iostream.h>

int main ()

{

int n1, n2

cout<<"Enter the number:";
cin>>n1;
cout<<"Enter the second number:";
cin>>n2;

// sum
int sum
sum=n1+n2;

//product
int product
product = n1 * n2;

//differance
int differance
differance = n1\n2;

//output
cout<< "The sum of these numbers are:";
cout<< sum;
cout<< "The diff of these numbers are:";
cout<< differance;
cout<< "The product of these numbers are:";
cout<< product;

return 0;

}

So how wrong is my program? My school sucks so much that I have to write my programs on a friggen piece of paper.

it looks good, except you forgot the ; after variable declarations

It is OK, but maybe for school the main function should be

main( int argc, char *argv[ ], char *envp[ ] )
{
program-statements
}

Why do that Vlatko? Very likely, he wont need the command line, and I doubt he will EVER need the environ strings.

Also, you tried doing difference with the vb integer division operator. The statement should (probably) be:

//quotient
int quotient
quotient = n1/n2;

 or...

//quotient
double quotient // most schools like doubles  o.O
quotient = double(n1)/n2;

Z.

Vlatko, he probably won't have VC++ at school and envp is Microsoft specific.

warrior, you should also add endl (end line) to your couts, or else it will all be one long line...

cout<< "The sum of these numbers are:"; 
cout<< sum << endl;

etc.

[Vlatko]

Well, i know that it is not likely that he will need the command line in apps like this, but i suggested that beacuse i know teachers must teach everything by the rules and many say that the main function should always be with argv and argc regardless of their need in the current app.

Also, iostream.h is deprecated. Use:

#include <iostream>

using namespace std;

int main(int argc, char **argv) {
    // Statements

    return 0;
}
