Table C.1 Relational and logical operands inMatlab,Fortran 77, and C++.
TheMatlaband C++ columns are nearly identical.

#include<iostream>

using namespace std;

int main()

{

cout << "Hello Themistocles \n";

return 0;

}

The output of the code is:

Hello Themistocles

InMatlab, the same code consists of one line alone:

disp "Hello Themistocles"

InFortran 77, the same code consists of two lines:

write (6,*) "Hello Themistocles"

end

Note that six blank spaces must be inserted at the beginning of each line.
