C++ program to find out the exponent of given number

#include<iostream>
#include<conio.h>

int main()
{
    system("cls");

    int i,b,p;
    double res;

    std::cout<<"Enter the base of the number = ";
    std::cin>>b;
    std::cout<<"Enter the power of the number = ";
    std::cin>>p;

    res = 1;
    for(i=1;i<=p;i++)
    {
        res = res*b;
    }

    std::cout<<"The result is = "<<res;

    getch();
    return 0;
}

Enter the base of the number = 5
Enter the power of the number = 4
The result is = 625
