In this post, we will write a **C++ program to find out the raise to the power of a given number by recursion**.

## C++ program to find out the raise to power of given number by recursion.

```
#include<iostream>
#include<conio.h>
#include<process.h>
int fun(int,int);
int main()
{
system("cls");
int a,b,res;
std::cout<<"Enter the base of number = ";
std::cin>>a;
std::cout<<"Enter the power of base = ";
std::cin>>b;
res = fun(a,b);
std::cout<<"The raise to power is = "<<res;
getch();
return 0;
}
fun(int a, int b)
{
int res;
if(b==0)
{
return(1);
exit(0);
}
else
{
res = a*fun(a,(b-1));
return(res);
}
}
```

### Output

Enter the base o number = 4 Enter the power of base = 5 The raise to power is = 1024
