The code
int funct(char, char);
is:
1. A function prototype
2. A function definition
3. A function call
4. None of the above - answer A function prototype
What is the return type of the following prototype:
int func(char x, double t);
1. char
2. int
3. double
4. func
5. void
6. char and double - answer int
Which of the following is a valid function call in C++ (assuming a
function called 'funct' exists):
1. funct;
2. funct x, y;
,3. funct();
4. int funct(); - answer funct();
Given the function prototype:
int funct(char x, double y, bool z);
which of the following would be the MOST correct call:
1. int funct(char x, double y, bool z);
2. funct(char x, double y, bool z);
3. funct('a', 2.5, true);
4. funct 'a', 2.5, true;
5. int answer = funct('a', 2.5, true); - answer int answer = funct('a',
2.5, true);
The function prototype
int foo (int y, int x = 4);
means:
1. The parameter y is passed by value.
2. The parameter x has a default value of 4.
3. The function foo returns an int value.
4. All of the above. - answer All of the above.
When two functions with the same name are defined in the same
scope, the function is:
1. static
2. inline
3. overridden
, 4. overloaded - answer overloaded
Overloaded functions must have:
1. different return types
2. different executable statements
3. different types and/or number of arguments
4. all of these - answer different types and/or number of arguments
Given the following code, what would the output be:
#include <iostream>using namespace std;
void func_one();void func_two();void func_three();
int x = 1;
int main() {int x = 2;func_one();cout << x << " ";func_two();
return 0;}
void func_one() {int x = 3;cout << x << " ";func_three();}
void func_two() {cout << x << " ";func_three();}
void func_three() {cout << x << " ";}
1. 3 1 2 1 1
2. 3 3 2 2 2
3. 3 2 2 2 2 - answer 31211
Consider the following statements and assume the standard
iostream library has been included:
void doub(int x) { x = x * 2; }void trip(int & x) { x = x * 3; }
int main () {
int x = 1;
