Thread: help involving powers and a clock?

okay, I need some help, I need to write a program where I can enter a first number, then a second one, and it raises the second one to the first one, only problem is I don't know how to do powers, if some one could write me a short quick example it would be much appreciated.
edit: here is my code so far, but it isnt working for some reason, could be because I'm not doing the powers right

Code:

#include <iostream>
#include <cmath>
using namespace std;

void powfun(int, int);
int main()
{
    int exp, fnum;
    
    cout << "Please enter an interger for an exponent" << endl;
    cin  >> exp;
    cout << "Now please enter an interger to be raised" << endl;
    cin  >> fnum;
    powfun(exp, fnum);
    system("pause");
    return 0;
}

void powfun(int exp, int fnum)
{
        cout << fnum << "Raised to the power of " << exp << " is " << fnum ^ exp << endl;
        
        return;
        
}

my second problem is basically to write a program that converts time passed (since program was opened) into the equivilant hours mins and seconds, this is what i have so far and it doesn't really work. basically it kind of counts the seconds, but not exactly

Code:

#include <iostream.h>
#include <time.h>
using namespace std;
int main ()
{
int sec_counter, min, hour, sec;
for (sec_counter = 1; sec_counter <= 60; sec_counter++)
{
cout << "Seconds Within the for loop: " << clock()/CLOCKS_PER_SEC;
system("pause");
}
system("pause");
return 0;
}

thanks for any help in advance

Code:

#include<windows.h>
#include<iostream.h>
using namespace std;

int main()
{
     int seconds, minutes, hours;
     bool running = false;
     minutes = 0;
     hours = 0;
     while(running == false)
     {
          Sleep(100);
          seconds++;
          if(seconds == 60)
          {
               seconds = seconds - 60;
               minutes++;
          }
          if(minutes == 60)
          {
               minutes = minutes - 60;
               hours++;
          }
          if(kbhit())
          {
              running = true;
          }
      }
       cout <<hours<<":"<<minutes<<":"<<seconds;
       Sleep(1000);
}

Don't know if that works, just a very basic time counter.

And to transform variable 1 into the base and variable 2 into an exponent.

Code:

#include<iostream>
using namespace std;

int main()
{
   int variable1,variable2;
   variable1 = 0; variable2 = 0;
   cout <<"Input Number for variable1:";
   cin>>variable1;
   cout <<"Input Number for variable2:";
   cin>>variable2;
   while(variable2 > 0)
   {
       variable1 = variable1 *variable1;
       variable2--;
   }
   cout <<variable1;
   system("pause");

And i didnt bother to look for power but this might work for you.
