Question

Write a program (C++) that requests the current time and a waiting time as two integers for the number of hours and the number of minutes to wait. The program then outputs what the time will be after the waiting period. Use 24-hour notation for the times. Include a loop that lets the user repeat this calculation for additional input values until the user says she or he wants to end the program.You can assume the wait time will always be less than 24 hours. You must meet the following requirements as well:

Your program must have three functions:

1. One to get the current time and the wait time using four reference parameters.
2. One to calculate the time after the wait time. This function will have six parameters:
   1. The current hour
   2. The current minutes
   3. The wait time hours
   4. The wait time minutes
   5. The finish time hours (reference parameter)
   6. The finish time minutes (reference parameter)
3. A function to output the finish time in 24-hour time notation with a colon in between the hours and the minutes and a zero before the minutes if the minutes are less than 10.

Answer 1

Please find the code below::::

#include<iostream>
using namespace std;

void getTime(int & currHour,int & currMin, int & waitHour, int & waitMin){
   cout<<"Enter current hours : ";
   cin>>currHour;
   cout<<"Enter current minutes : ";
   cin>>currMin;
   cout<<"Enter wait hours : ";
   cin>>waitHour;
   cout<<"Enter wait minutes : ";
   cin>>waitMin;
}

void calculateTime(int & currHour,int & currMin, int & waitHour, int & waitMin,int & finishHour,int & finishMin){
   finishHour = currHour + waitHour;
   finishMin = currMin + waitMin;
   //if minute is greater than 60 increase hour
   finishHour += finishMin/60;
   finishMin /= 60;
}

void printTime(int & finishHour,int & finishMin){
   if(finishHour<10){
       cout<<"0"<<finishHour;
   }else{
       cout<<finishHour;
   }
   cout<<":";
   if(finishMin<10){
       cout<<"0"<<finishMin;
   }else{
       cout<<finishMin;
   }
}
int main()
{
   int currHour,currTime,waitHour,waitMin,finishHour,finishMin;
   getTime(currHour,currTime,waitHour,waitMin);
   calculateTime(currHour,currTime,waitHour,waitMin,finishHour,finishMin);
   cout<<"Finish time is ----> ";
   printTime(finishHour,finishMin);
   return 0;
}

output:
