C Language Basic Quiz Test!

1. C language developed on pdp11 computer in bell laboratory?

True

False

The statement is true. C language was indeed developed on the PDP-11 computer at Bell Laboratories. The language was created by Dennis Ritchie in the early 1970s as a successor to the B programming language. The PDP-11 computer was a popular machine at that time, and its hardware architecture heavily influenced the design of the C language.

2. Ternary opretor is subsitute of?

Switchcase

If..else

Do..while

While

The correct answer is if..else. The ternary operator can be used as a substitute for an if..else statement in certain cases. It provides a concise way to write conditional statements and allows for a more compact code. The syntax of the ternary operator is "condition ? expression1 : expression2", where the condition is evaluated and if true, expression1 is executed, otherwise expression2 is executed. This makes it a suitable alternative to if..else statements when there are simple conditional checks that need to be made.

4. Pointer has how many special characters?

One

Two

Three

Four

The correct answer is "two" because a pointer can have two special characters, which are the asterisk (*) and the ampersand (&). The asterisk is used to declare a pointer variable and to dereference a pointer, while the ampersand is used to get the address of a variable.

5. What's wrong in this:for(;;)

Infiniteloop

Compile error

Warrning

None of above

The given code "for(;;)" is a shorthand way of writing an infinite loop. In this case, there are no conditions specified in the loop, so it will continue indefinitely. Therefore, the correct answer is "infiniteloop".
