Correct Answer: Error occurs because we have mixed the ANSI prototype with K & R style of function definition When we use ANSI prototype for a function and pass a float to the function it is promoted to a double When the function accepts this double into a float a type mismatch occurs hence the error The remedy for this error could be to define the function as : int fun (float aa) { }
Correct Answer: The Lord of the Rings
Correct Answer: 0..1..2
Explanation:
enum assigns numbers starting from 0, if not explicitly defined.
Correct Answer: 00 00 AC 40
Correct Answer: Here in this declaration public static void main string[] args, each keyword has its importance 1 public - Here public is an access specifier which allows the main method to be accessible everywhere 2 static - static helps the main method to get loaded without getting called by any instance/object 3 void - void clarifies that the main method will not return any value 4 main - It's the name of the method 5 String[] args - Here we are defining a String array to pass arguments at the command line args is the variable name of the String array
Correct Answer: Compilation error
Explanation:
Size of any array in c cannot be constantan variable.
Correct Answer: TRUE
Explanation:
A function cannot be defined inside the another function, but a function can be called inside a another function.
Correct Answer: Compilation error
Explanation:
We cannot use special character ? in the variable name.
Variable name can have only underscore.
Correct Answer: String operations
Explanation:
SNOBOL is a high-level computer programming language used especially in manipulating textual data. It is mainly used for string operations and was developed between 1962 and 1967.
Correct Answer: Compile time error
