Thread: Exponents??

Pardon the "n00b" question, but if there's a sqrt() function in <math> then why the heck doesn't

Code:

std::cout<<i^2;

give me i squared? (I know, ^ is some kind of logical operator.)

Where are the dang exponents?

Code:

#include <iostream>

int main ()
{
int i = 1;
while (i <= 10)

    {
    std::cout<<i*i<<std::endl;
    ++i;


    }
    
system("PAUSE");
return 0;
}

I've googled and searched the site but I'm sure you guys can answer this in far less time that it will take me to flounder around.

Thanks!

Perfect! Thanks!

Code:

#include <iostream>
#include <cmath>

int main ()
{
int i = 0;
while (i <= 16)

    {
    std::cout<<pow(2,i)<<std::endl;
    ++i;
    }
    
system("PAUSE");
return 0;
}

if you want to make a power function yourself:

Code:

double power(double base, double exp)
{
    if(exp == 1)
        return base;
    if(exp == 0)
        return 0;
    else
       return base * power(base, exp - 1);
}
