Question

2.3 Code Practice: Question 3

Write a program that accepts a time as an hour and minute. Add 15 minutes to the time, and output the result.

Example 1:

Enter the hour: 8
Enter the minute: 15
It displays:

Hours: 8
Minutes: 30
Example 2:

Enter the hour: 9
Enter the minute: 46
It displays:

Hours: 10
Minutes: 1

Answer 1

Code in C++

Step-by-step explanation:

C++ Code

#include<iostream> //for input and output

using namespace std;

int main()

{

int hour;

int minute;

cout<<"Enter the hour:";

cin>> hour;

cout<<"Enter the minute:";

cin>>minute;

minute = minute+15;

if(minute>=60){

hour++;

minute=minute-60;

}

if(hour>=24){

hour=0;

}

cout<<"Hours: "<<hour<<endl;

cout<<"Minutes:"<<minute;

return 0;

}

Code Explanation

First we need to declare two int variables to hold hour and minute values input from user.

Check if by adding 15 minutes into minute entered by user is greater then or equal to 60 then increment into hour and subtract 60 from minute.

Another check is that if user enters more then 24 hour or by making increment into hour, the hour values i greater then or equal to 24 then we need to change the hour to 0.

Result

Case 1:

Enter the hour:8

Enter the minute:15

Hours: 8

Minutes:30

Case 2:

Enter the hour:9

Enter the minute:46

Hours: 10

Minutes:1
