Yes thanks alot. I got my code to work now.
Here's the final code that worked:
#include <iostream>
using namespace std;
int menu(void);//Menu is ran so user can select their choice
double prob1(void);//Declares prob1
double prob2(void);//Declares prob2
double prob3(void);//Declares prob3
double prob4(void);//Declares prob4
int main (void)
{
cout << "INTRAVENOUS RATE ASSISTANT\n\n";//Title at begining of program
int task;//Selection chosen for if statments
do//Runs users task and repeats menu if user selects correct value
{
task = menu ();//Tasks are brought in so user can decide which one to run
if (task == 1)//Runs task 1 and returns value
cout << "The drop rate per minute is "<<prob1()<<"."<<"\n\n";
else if(task == 2)//Runs task 2 and returns value
cout << "The rate in milliliters per hour is "<<prob2()<<"."<<"\n\n";
else if(task == 3)//Runs task 3 and returns value
cout << "The rate in milliliters per hour is "<<prob3()<<"."<<"\n\n";
else if(task == 4)//Runs task 4 and returns value
cout << "The rate in milliliters per hour is "<<prob4()<<"."<<"\n\n";
}while(task !=5);//Runs do statment as long as task does not equal 5
cout <<"\nProblem: 5\n";//Quits program when task = 5
cout <<"Goodbye...\n\n";
system("PAUSE");
return 0;
}
int menu(void)
{
int task;//Declares users task
cout << "Enter the number of the problem you wish to solve.\n\n";
cout << "GIVEN MEDICAL ORDER IN: CALCULATE RATE IN:\n\n";
cout << "1) ml/hr and tubing drop factor drops/min\n";
cout << "2) 1 L for n hrs ml/hr\n";
cout << "3) mg/kg/hr and concentration in mg/ml ml/hr\n";
cout << "4) units/hr and concentration in units/ml ml/hr\n";
cout << "5) QUIT\n";
cout << "Enter your selection: ";
cin >> task;//User enters their task
return task;//Returns task to main
}
double prob1(void) //First menu option, User types 1 the following will be used
{
double mlhr=0.0, dropfactor=0.0, droprate=0.0;//Declares variables for prob1
cout << "\n\nProblem: 1\n";

cout.setf(ios::fixed);
cout.precision(0);//Numbers are rounded to nearest whole number
droprate = ( mlhr * dropfactor) /60;//Formula for calculation
return droprate;//Droprate returned to main
}
double prob2(void) //Second menu option, User types 2 the following will be used
{
double hours=0.0, droprate=0.0;//Declares variable for prob2
cout << "\n\nProblem: 2\n";
cout << "Enter the number of hours: ";
cin >> hours;//User enters the number of hours
cout.setf(ios::fixed);
cout.precision(0);//Rounds to the nearest whole number
droprate = 1000/hours;//Formula for calculation
return droprate;//Returns droprate to main
}
double prob3(void) //Third menu option, User types 3 the following will be used
{
double mgkghr=0.0, kg=0.0, mgml=0.0, droprate=0.0;//Declares variable for prob3
cout << "\n\nProblem: 3\n";
cout << "Enter rate in mg/kg/hr: ";
cin >> mgkghr;//User enters mg/kg/hr
cout << "Enter the patient weight in kg: ";
cin >> kg;//User enters patient weight in kg
cout << "Enter the concentration in mg/ml: ";
cin >> mgml;//User enters concentration in mg/ml
cout.setf(ios::fixed);
cout.precision(0);//Rounds to the nearest whole number
droprate = (mgkghr * kg)/mgml;//Formula used for calculations
return droprate;//Returns droprate to main
}
double prob4(void) //Fourth menu option, User types 4 the following will be used
{
double unitshr=0.0, unitsml=0.0, droprate=0.0;//Declares variable for prob4
cout << "\n\nProblem: 4\n";
cout << "Enter the rate in units/hr: ";
cin >> unitshr;//User enters rate in units/hr
cout << "Enter the concentration in units/ml: ";
cin >> unitsml;//User enters units/hr
cout.setf(ios::fixed);
cout.precision(0);//Rounds to the nearest whole number
droprate = unitshr/unitsml;//Formula for calculation
return droprate;//Returns droprate to main
