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:
Size of any array in c cannot be constantan variable.
Correct Answer: Looping
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: 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
Correct Answer: Cohesion is the OO principle most closely associated with making sure that a class is designed with a single, well-focused purpose
