Question

2.2 Code Practice: Question 1
Ask the user to input an integer. Print out the next three consecutive numbers.

Answer 1

Answer:

num1=int(raw_input(enter your number))

print"next three consecutive numbers are",num1+1,num1+2,num1+3

Answer 2

Answer:

Following is the C++ code for the problem.

#include <iostream>

using namespace std;

int main() {

int z;

cout<<"Enter the number"<<endl;

cin>>z;//taking the input.

cout<<"Next three consecutive integers are as following:"<<endl;

for(int i=1;i<=3;i++) //for loop to print three integers.

{

    cout<<++z<<endl;//printing the integers.

}

return 0;

}

Output:-

Enter the number

5

Next three consecutive integers are as following:

6

7

8

Explanation:

I have used for loop to print next 3 consecutive integers after taking the input from the user.Loop is better method then writing three print statements.In the for loop I am printing ++z means print z+1. ++ is an increment operator which increases the value by 1.In our case it is pre increment operator.It first increases the value then operates on it.
