Passing Arguments

[vgarza]

trying to use a void function below. How do I correct scope not declared for numYears and numChildren?

4#include <iostream>
5#include <cmath>
6using namespace std;
7
8// Function prototype
9void tellFortune(int);
10
11/***** main *****/
12int main()
13{
14 int numYears,
15 numChildren;
16
17 cout << "This program can tell your future. \n"
18 << "Enter two integers separated by a space: ";
19
20 cin >> numYears >> numChildren;
21
22 tellFortune(numYears, numChildren);
23
24
25 return 0;
26}
27
28/***** tellFortune *****/
29void tellFortune()
30{
31 numYears = abs(numYears) % 5; // Convert to a positive integer 0 to 4
32 numChildren = abs(numChildren) % 6; // Convert to a positive integer 0 to 5
33
34 cout << "\nYou will be married in " << numYears << " years "
35 << "and will have " << numChildren << " children.\n";
36}

pass them as references

void tellFortune( int& numYears, int& numChildern ){ 

don't copy the line numbers and put your code inside a code tag next time

For this, it doesn't seem like it needs to be pass by reference as it doesn't need them again.

Something like this will also work:

void tellFortune(int numYears, int numChildren)
{
     your code... 
}

Also make sure that both the function name and description match!

You have void tellFortune(int);

and void tellFortune()

when it should be

void tellFortune(int numYears, int numChildren);

AND

void tellFortune(int numYears, int numChildren)
{}
