Check the explanation

Explanation:

Code in C++::

#include <iostream>

using namespace std;

void PrintFactorial(int factCounter, int factValue){

int nextCounter = 0;

int nextValue = 0;

if (factCounter == 0) { // Base case: 0! = 1

cout << "1" << endl;

}

else if (factCounter == 1) { // Base case: Print 1 and result

cout << factCounter << " = " << factValue << endl;

}

else { // Recursive case

cout << factCounter << " * ";

nextCounter = factCounter - 1;

nextValue = nextCounter * factValue;

/* Your solution goes here */

/**

* We just need to call the function PrintFactorial() recursively

* and pass the two parameters that are just calculated as nextCounter for factCounter

* and nextValue as factValue.

*/

PrintFactorial(nextCounter,nextValue);

}

}

int main() {

int userVal = 0;

userVal = 5;

cout << userVal << "! = ";

PrintFactorial(userVal, userVal);

return 0;

}
