Q1. Fibonacci Series in C/C++, i++ and ++i
Ans. 
Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones.
• In C/C++, i++ is post-increment operator which increments the value of i after the current operation is executed.

• In C/C++, ++i is pre-increment operator which increments the value of i before the current operation is executed.

• Example: Fibonacci series using i++ - int a = 0, b = 1, c, n = 10; for(int i = 2; i < n; i++) { c =...read more

Q2. Explain different types of flip flops ,.
Ans. 
Flip flops are sequential circuits used in digital electronics to store one bit of information.
• SR flip flop: basic flip flop with two inputs (S and R) and two outputs (Q and Q').

• D flip flop: data flip flop with single data input (D) and clock input (CLK).

• JK flip flop: versatile flip flop with J, K, and clock inputs.

• T flip flop: toggling flip flop with single input (T) and clock input.
