Problem:

Please find out the problem in my code and let me know where I am wrong.

#include <iostream>
#include <string>
using namespace std;

string userInput();
int wordLengthFunction(string word);
int permutation(int wordLength);

int main()
{
    string word = userInput();
    int wordLength = wordLengthFunction(string word);

    cout << word << " has " << permutation(wordLength) << " permutations." << endl;

    return 0;
}

string userInput()
{
    string word;

    cout << "Please enter a word: ";
    cin >> word;

    return word;
}

int wordLengthFunction(string word)
{
    int wordLength;

    wordLength = word.length();

    return wordLength;
}

int permutation(int wordLength)
{    
    if (wordLength == 1)
    {
        return wordLength;
    }
    else
    {
        return wordLength * permutation(wordLength - 1);
    }    
}

Solution:

You should not be repeating the string part when sending parameters.

Write like this instead of the wrong one.

int wordLength = wordLengthFunction(word);

problem: I'm new to C++ and programming, and have run into a mistake that I can't sort out. At the point when I attempt to run the program, I get the accompanying blunder message: stringPerm.cpp: In capacity 'int main()': stringPerm.cpp:12: mistake: expected ... int permutation(int wordLength) { if (wordLength == 1) { return wordLength; } else { return wordLength * permutation(wordLength - 1); } }

Problem: In the implementation file, I get the above error on line 2 of the implementation code. I have used this same exact syntax in another program with successful compilation and correctly functioning results, so I am quite confused. There are three different function ... their respective lines. I assume I am making a small error but I really can't seem to figure it out. PLease guide
