Q424.Suppose z is an integer while z and y are long variables. If you write z = z + y; in your C program, which of the following will happen?
Correct Answer: D
In C, the operands in z + y are promoted to the larger type (long). After addition, the long result is truncated back to int to be assigned back to z.
Q425.In C programming, the loop that is executed at least once (even if the condition is false) is called ______ loop.
Correct Answer: A
A do-while loop is a post-test loop where the body is executed before checking the condition, ensuring at least one full execution.
Q426.Which of the following is TRUE for a variable defined with the keyword const and initialized to a value in C language?
Correct Answer: C
The const modifier makes a variable read-only after initialization, preventing any modification to its value during runtime.
Q427.Which of the following does NOT qualify to be the name of a variable in C language?
Correct Answer: D
The term 'define' is a reserved preprocessor directive keyword in C and cannot be declared as a custom variable name.
Q428.A set of programs containing instructions to coordinate all the activities of a computer is called ______?
Correct Answer: C
The Operating System is the primary system software package that coordinates hardware resources, runs applications, and provides a platform for users.
Q429.Which of the following is NOT a productivity software?
Correct Answer: A
Audio and video players are categorized as media or entertainment applications rather than professional office productivity software.
Q430.Track of location of all files stored in a system is kept by _____?
Correct Answer: B

Q434.Which one is the complete information about the database?
Correct Answer: C
A record (row or tuple) contains a complete set of related fields providing complete, structured information about a single entity inside a database table.
Q435.Plug and Play (PnP) technology allows an operating system to recognize connected devices without requiring manual installation of a ______?
Correct Answer: C
Plug and Play (PnP) automatically detects and configures hardware components, eliminating the need to manually install device drivers.
Q436.Which loop control statement is the opposite of the 'break' statement and is also referred to as a bypass statement?
Correct Answer: B
The 'continue' statement is the opposite of 'break'. It skips the remainder of the current loop iteration and 'bypasses' it to start the next iteration.
Q437.In assembly language programming, the symbolic names or codes used in place of raw binary instructions are called ______?
Correct Answer: B
Mnemonics are English-like abbreviations (e.g., ADD, SUB, MOV) used in assembly language to represent underlying binary machine instructions.
Q438.The 'getche()' C/C++ library function reads a single character from the keyboard and immediately ______ it on the screen.
Correct Answer: B
