I'm so proud of myself  . I made first workign program in C++ LOL.
I coded the thing all on my own the only thing i give credits to is
Cx for cin.get and cin.ignore., other than that i did all by myself
*play im a big boy know song* LOL, k so. ill post the .exe with source if anyone wants. (10-15 lines of code but w/e )
here ya go!
-... can't post the exe or the source file.... ill just copy paste code....
| Code: |
#include <iostream>
#include <cstdlib>
using namespace std;
int main()
{
int num1, num2, num3;
cout << "Enter your first number" << endl;
cin >> num1;
cout << "Enter your second number" << endl;
cin >> num2;
cout << "Enter your third number" << endl;
cin >> num3;
cout << num1 << "+" << num2 << "+" << num3 << "=" << num1+num2+num3 << endl;
cin.ignore();
cin.get();
return 0;

| im trying to make it so that you can enter 3 numbers and then have it devide by 3 to find the average, but the math is off... do you know if the command for division is "/" ?

this is my modified code from what i added in the start of the thread
| Code: |
#include <iostream>
#include <cstdlib>
using namespace std;
int main()
{
int num1, num2, num3, num4;
num4 = 3;
cout << "Enter your first number" << endl;
cin >> num1;
cout << "Enter your second number" << endl;
cin >> num2;
cout << "Enter your third number" << endl;
cin >> num3;
cout << "The average of your numbers" << "=" << num1+num2+num3/num4 << endl;
cin.ignore();
cin.get();
return 0;
}
|
i use / and the math ends up all wrong...
example: i enter 5,5,5 for my number which = 15 and then it should divide (/) by num4= 3 and 15/3 = 5. it gets 11 ...

/ = divide
% = modulus (remainder)
Order of operations
(a+b+c) / d
It will add first then divide

Try using Parenthesis on the math. Remember the Order of Operations. Adding comes last, so division and multiply come first.
Whatever is in the parenthesis in math, the compiler does first, stores it somewhere, and uses it to add whatever number you requested.

| Code: |
num1+num2+num3/num4

will this know to add numbs 1-3 then divide by num4, or do i have to put like a pause, then tell to divide.

(num1+num2+num3) / num4
so basicly
First perform any calculations inside parentheses.
Next perform all multiplications and divisions, working from left to right.
Lastly, perform all additions and subtractions, working from left to right.

thanks xD it was probably think 1/4 of the num3.
IT WORKED!
