The %d code is a printf format specifier that says to take the next argument and convert it into a decimal, based on an int.
for (int i = -3; i < 4; ++i) printf ("i: %d i squared: %d\n", i, i*i);
will print
i: -3 i squared: 9
i: -2 i squared: 4
i: -1 i squared: 1
i: 0 i squared: 0
i: 1 i squared: 1
i: 2 i squared: 4
i: 3 i squared: 9
on stdout.

There is no meaning for the C in C-language. Previously , there was a language called BCPL (Basic combined programming language) ,Ken thompson improved this language and named as B language. After several modifications and inclusion of advanced features such as Pointers , Dennis Richie named it as C , (C comes after B in Alphabetical Order) So , name for that Language came in this way. Later Bjourne Strostrup included Object Oriented features to C , and Named 'C with Classes ' and later C++.
