Wrong Answer:
Percentage: %
- A. Data file
- B. stderr
- C. string
- D. stdin
Remarks:
Explanation: string
- A. char *
- B. struct
- C. void
- D. none of the mentioned
Remarks:
Explanation: none
- A. A function that calls another function
- B. A function that returns a pointer to another function
- C. A function that calls itself
- D. A function that takes no arguments
Remarks:
Explanation:
Answer: C) A function that calls itself. A recursive function is a function that calls itself either directly or indirectly. It is useful for solving problems that can be broken down into smaller sub-problems that are identical or similar in nature to the original problem.
- A. int
- B. void
- C. float
- D. buit
Remarks:
Explanation:
Answer: d. buit
Explanation: In C language, a function can return any data type including int, void, float, double, char, pointers, structures, and unions. However, buit is not a valid data type for function return value.
- A. A recursive function cannot call itself.
- B. A recursive function must have a base case to terminate the recursion.
- C. A recursive function must have a return type of void.
- D. A recursive function cannot be called from another function.
Remarks:
Explanation:
Answer: b. A recursive function must have a base case to terminate the recursion.
Explanation: A recursive function is a function that calls itself. To prevent infinite recursion, a recursive function must have a base case that terminates the recursion. The base case is a condition that is tested at each recursive call to determine whether the recursion should continue or terminate.
- A. Function arguments are always passed by value.
- B. Function arguments are always passed by reference.
- C. Function arguments can be passed by value or by reference.
- D. Function arguments can be passed by value, bot not by reference
Remarks:
Explanation:
Answer: c. Function arguments can be passed by value or by reference.
Explanation: In C language, function arguments can be passed by value or by reference. When an argument is passed by value, a copy of the argument value is passed to the function. When an argument is passed by reference, a reference to the argument variable is passed to the function.
- A. To define the implementation of a function.
- B. To declare the return type of a function.
- C. To declare the function name and its parameter types.
- D. To declare the function name and its return type.
Remarks:
Explanation:
Answer: c. To declare the function name and its parameter types.
Explanation: A function prototype is a declaration of the function name and its parameter types, but not its implementation or return type. It allows the compiler to know about the function before it is called, so that it can perform type checking and generate appropriate code.
- A. Call by value passes the address of the argument to the function, while call by reference passes a copy of the argument value.
- B. Call by value passes a copy of the argument value to the function, while call by reference passes a reference to the argument variable.
- C. Call by value and call by reference are the same thing.
- D. Call by value passes a reference to the argument variable, while call by reference passes a copy of the argument value.
Remarks:
Explanation:
Answer: b. Call by value passes a copy of the argument value to the function, while call by reference passes a reference to the argument variable.
Explanation: In call by value, a copy of the argument value is passed to the function, while in call by reference, a reference to the argument variable is passed to the function. Call by reference allows the function to modify the argument variable, while call by value does not.
- A. void
- B. int
- C. char
- D. Both A and B and C
Remarks:
Explanation:
Answer: D) Both A and B.
A function in C can have either a return type of void or an integer type (int, char, short, long, etc.) or a pointer type.
- A. A function that takes no arguments
- B. A declaration of a function that specifies the function's name, return type, and parameter types
- C. A function that returns a pointer to another function
- D. A function that has a variable number of arguments
Remarks:
Explanation:
Answer: B) A declaration of a function that specifies the function's name, return type, and parameter types. A function prototype is a declaration of a function that appears before the function is defined or called. It specifies the function's name, return type, and parameter types.
