Write a program that inputs the number of hours you are taking this semester and outputs how much time outside of class you should spend studying. (hint: every 1 credit hour = 2-3 hours spent outside of class).

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

   int a,b,c;

   //ask to enter semester hours

   cout<<"Enter the number of hours in the semester:";

   // read the semester hours

  cin>>a;

  //print the semester hours

  cout<<"You have taken "<<a<<" hours in semester."<<endl;

  // find the time spend outside of the class

  b=a*2;

  c=a*3;

  // print the time outside class

  cout<<"you should spend "<<b<<"-"<<c<<" hours outside of class"<<endl;

return 0;

}

Explanation:

Read the hours taken in the semester from user and assign it to "a".

Then find its 2 and 3 time.This will be the time user should spend outside

of the class.

Output:

Enter the number of hours in the semester:15

You have taken 15 hours in semester.

you should spend 30-45 hours outside of class  

a variable of array type holds a reference of object

array are commonly used in computer program to organize data so that a related set of values

array are using zero base indexing it start with 0.

all component of array have same type, two different types doesn't use in single array

if array are store 10 quantities its index value varies from 0 to 9.

it stores 1st quantity value in index value 0 and this process will same till index value 9.
