Answer:

For any program that we write the basic things that we need to do is take the input and print the expected output.

In C++ you can take the input using cin and print the output using cout.Unlike C where you need the format specifier in printf and scanf, here you can use cin and cout.

Taking Input:

If you want to input a number: cin>>n , where n is the number.

If you want to input a number and a string: cin>>n>>s, where s is the string.

Printing output:

If you want to output a single number: cout<<n

If you want to output a number and a string separated by a new line: cout<<n<<endl<<s (where endl moves the pinter to the new line and then string gets printed.)
