• Important 2nd year computer chapter 11 short questions for Intermediate part-II students.
• What is a Control structure? : Ans: A control structure is a statement used to control flow of execution in a program or function. Control structure is used to combine individual instructions into a single logical unit. This unit has one entry point and one exit point. Program logic is implemented with the help of control structures. Three kinds of control structures are used to control flow of execution of instructions.

• What is meant by sequence-structure? : Ans: In sequence structure the instructions of program executes one after the other in the order in which are written. It is also called the default flow of a program. The program starts execution from the first instruction and all instructions are executed one by one in a sequence.

• What is a break statement? : Ans: Break is a keyword. It is the last statement in each case. It is used to transfer flow of control outside a code block. When break statement executes in switch statement the flow of control is transferred to the first instruction after switch block.
