Thread: local function definitions are illegal?? What the...??

You need to define the two functions that you want to use, just like you define the variable in your program

Code:

#include <iostream.h> 
#include <stdio.h> 
#include <stdlib.h> 

long double amount = 0; // these are global vars. it is safer to
long double earn = 0;     // move these inside of the main fun.
long double percent = 0; // and pass b/n functions.
int weeks = 0; 
int result = 0; 


void verOne(); // Define your functions too
void verTwo(); // Define your functions too


int main() 
{ 
	int choice; 
	cout << "Would you like to run version 1 or version 2? "; 
	cin >> choice; 

	switch(choice) 
	{ 
		case 1: verOne(); 
				break; 

		case 2: verTwo(); 
				break; 
	} 
	return 0; 
}

void verOne() 
{ 
	// get info 
	system("cls"); 
	cout << "Enter the amount of money that you would like to save:$"; 
	cin >> amount; 
	cout << "\n"; 

	cout << "Enter the amount of money that you earn each week:$"; 
	cin >> earn; 
	cout << "\n"; 

	cout << "Enter the percentage of your weekly earnings that you would\n"; 
	cout << "like to save each week: "; 
	cin >> percent; 
	cout << "\n"; 

	// calculate end result 
	percent = percent/earn * 100; 
	result = amount/percent; 

	if(result < 1) 
	{ 
		cout << "It would take you 1 week to reach your target.\n"; 
		exit(0); 
	} 
	else 
	{ 
		cout << "It would take you "; 
		cout << result; 
		cout << " week(s) to reach your target.\n"; 

		exit(0); 
	}
}

void verTwo() 
{ 
	//get info 
	system("cls"); 
	cout << "Enter the amount of money that you would like to save:$"; 
	cin >> amount; 
	cout << "\n"; 

	cout << "Enter the maximum amount of weeks that you have to save this money: "; 
	cin >> weeks; 

	// calculate result 
	result = amount/weeks; 
	cout << "You would have to save $"; 
	cout << result; 
	cout << " each week for "; 
	cout << weeks; 
	cout << " weeks."; 
	cout << "\n"; 

	exit(0); 
}
