(C++) Write code to complete RaiseToPower(). Sample output if userBase is 4 and userExponent is 2 is shown below. Note: This example is for practicing recursion; a non-recursive function, or using the built-in function pow(), would be more common.4^2 = 16Given: #nclude using namespace std;int RaiseToPower(int baseVal, int exponentVal){int resultVal = 0;if (exponentVal == 0) {resultVal = 1;}else {resultVal = baseVal * //your solution goes here;}return resultVal;}int main() {int userBase = 0;int userExponent = 0;userBase = 4;userExponent = 2;cout << userBase << "^" << userExponent << " = "<< RaiseToPower(userBase, userExponent) << endl;return 0;}
