C++ -- expected primary-expression before ' '

Question

I am new to C++ and programming, and have run into an error that I cannot figure out. When I try to run the program, I get the following error message:

stringPerm.cpp: In function ‘int main()’: stringPerm.cpp:12: error: expected primary-expression before ‘word’ 

I've also tried defining the variables on a separate line before assigning them to the functions, but I end up getting the same error message.

Can anyone offer some advice about this? Thanks in advance!

See code below:

#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);     }     } 

Answer 1

You don't need "string" in your call to wordLengthFunction().

int wordLength = wordLengthFunction(string word);

should be

int wordLength = wordLengthFunction(word);

Answer 2

Change

int wordLength = wordLengthFunction(string word); 

to

int wordLength = wordLengthFunction(word);
