C++ local variables pass to functions

#include <iostream>
using namespace std;
#include <iomanip.h>
pr_init(char initial);  // Prototypes discussed later.
pr_other(int age, float salary);
int main()/*from   ww  w. ja va2s . c om*/

   int age;

   // Fill these variables in main().
   cout << "What is your initial? ";
   cin >> initial;
   cout << "What is your age? ";

   cin >> salary;
   pr_init(initial);
   pr_other(age, salary);  
   return 0;
