Answer:
Following are the program in C++ language :
#include <iostream> // header file
using namespace std; // using namespace
int main() // main method
{
int amount,total=0; // two int variable declaration
cout<<" enter amount:";
cin>>amount; // read input amount first time
total=total+amount; // first calculation
cout<<" enter amount:";
cin>>amount; //read input amount second time
total=total+amount;// second calculation
cout<<" enter amount:";
cin>>amount;// read input amount third time
total=total+amount;// third calculation
cout<<"total:"<<total; // display total
return 0;
}
Output:
enter amount:12
enter amount:12
enter amount:12
total:36
Explanation:
Following are the explanation of program which is mention above
- Declared the two variable total and amount of int type .
- Initialize the variable total to "0".
- Read the 3 input in "amount" variable in one by one by using cin function and adding their value to the "total "variable .
- Finally display the total.

class divide {
public static void main (String[] args) {
Scanner num=new Scanner(System.in);//scanner object.
int userNum=num.nextInt();
while(userNum>1)//while loop.
{
userNum/=2;//dividing the userNum.
System.out.print(userNum+" ");//printing the userNum.
}
}
}
Input:-
40
Output:-
20 10 5 2 1
Input:-
2
Output:-
1
Input:-
0
Output:-
No Output
Input:-
-1
Output:-
No Output.
Explanation:
In the program While loop is used.In the while loop it divides the userNum by 2 in each iteration and prints the value of userNum.The inputs and corresponding outputs are written in the answer.
