broken code

[Acidburn]

Whilst I shouldnt have posted the entire code up, I see no other option :(

#include <iostream> // cout << endl ...
#include <fstream> // for reading in the file ...
#include <string> // for comparing strings ...

using namespace std;

	"if", "then" , "else", "function"};

void func_t(char &sym);

void func_E(char &sym);

int main()
{
	//cout << temp[10];
		file_input();
	cout << "Contents of global array is : " << ::temp << endl;
	char  * a;
	a = getsym();
 func_S(a);


return 0;
}

//sorts out the temp array and returns tokens.

I get the follow errors at compile time:

Can anyone help? Please

You're trying to pass a memory address of a character to a function that, as declared, expects you to pass an individual character. Passing a character by reference is not the same thing as passing a pointer to a character.
