Key points In C++In Java In order to give one line gap we use endl In C++ endl will give the one line gap and cursor will go to next line cout<<"entre radius"<<endl; In above instruction entre ra dius will print and <<endl will provide the one line gap Join string with variable we use string << variablename; In order to give one line gap we use System.out.println Here ln will give one line break if we use System.out.print it do not give one line break and print in the same line If we want to join string with variable value we use + sign
