Explanation

An overloaded function is really just a set of different functions that happen to have the same name. The determination of which function to use for a particular call is resolved at compile time.

Explanation

Variable scope refers to the extent of code in which a variable can be referenced.

Variables defined inside a function are called local variables.

The scope of local variables and dummy arguments is limited to the function in which they are defined.

Explanation

C++ and Java differ in their platform dependency, memory management, and use of classes.

C++ is platform dependent and needs to be compiled on every platform.

Java is platform-independent.

Once it's compiled into bytecode it can be executed on any platform.

Explanation

The valid output statement in C language among the given options is printf("Hello");.

In C programming, the printf() function is the standard library function used to display formatted output on the console.

It is part of the stdio.h header file, which needs to be included in your C program using #include <stdio.h>.

Options A, B, and C (display(), output(), print()) are not standard C library functions for outputting text to the console.

Explanation

do-until is not a valid loop structure in C programming.

C provides for, while, and do-while loops for iteration.

Explanation

The conditional operator (? :) is a shorthand for the if-else statement.

It evaluates a condition and returns one value if true, another if false.

Explanation

The format specifier %c is used in scanf to read a single character.

So, km must be a character variable, e.g., char km;.

Explanation

r is the carriage return escape sequence, which moves the cursor to the beginning of the current line.

It does not move to the next line, unlike n (newline).

Explanation

In C, 9 and 4 are integers, so 9 / 4 = 2 (integer division, fractional part is discarded).

Then, 2 * 2 = 4

Explanation

 The code ')A1B2' follows a specific format

Where it begins with a special character (alpha), followed by a numeric digit, a letter, and another numeric digit.

The correct option that matches this format is ')A1B2'.
