Can anybody fix it?

Answer 1

^ is reserved for bitwise XOR

Answer 2

Why not use pow function from <math.h>?

Answer 3

maybe use for loop and multiply itself on each iteration?

Answer 4

pow() function:

C++ operators:

Answer 5

#include <iostream>
using namespace std;
int pow(int a, int b) {
int base = a;
for(int i=1;i<b;i++){
a*=base;
}
return a;
}

int main()
{
int a;
int b;
cout << "Vnesi stevili za eksponent in osnovo: " << '\n';
cin >> a;
cin>>b;
cout << "Rezultat = " << pow(a,b);
return 0;

}

Answer 6

I still do not know what expression is returning in pow() definition.

Answer 7

There is no special arithmetic operator.

Answer 8

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

double power(double a, int b) {
return pow(a,(double)b);
}

int main()
{
double a = 3.2;
int b = 5;
cout << "Vnesi stevili za eksponent in osnovo: " << '\n';
cin >> a >> b;
power(a,b);
cout << "Rezultat = " << pow(a,b);
}

you can use this way or else use loop
for (int i=1;i<=b;i++)
a*=b;
return a;
here a stores power value where a raised to b

Answer 9

Ye, it works. I know that here is type conversion but I have not how to do that.

Answer 11

Chicu, in your example I think you use pointer, right?

Answer 12

Marjan, no he uses recursion, which is not a good implementation because of memory consumption and program optimization.

Answer 13

Vasile i'm not going to argue with you on memory and optimisation since this is a simple function not a game engine,i'm wondering why you didn't said that it should be done in assembly
