do is the top of a loop
I'm not going to answer the question you posted -- write a small test program and see for yourself what the answer is. Just post that code in a main() function and you have it done.

; it will print out "76"
; do means an action will happen and then it will check if the while ;statement is true, if so again it will go to do or else it will exit from ;do while loop
I = I + 25; // it will add 25 to I
while ( I > 50 ); // then it will check if I is more than 50, if so it will again add 25 to I
else
it will print I out.

Practice problems mean you type them into your compiler, compile them, and see how they work. That's the best way to figure out how things work. For these, forget the internet -- pretend it doesn't exist. All you have is you, your computer, and your compiler.
