C++ Institute CPA-21-02 Sample Questions:

01. The complete program below includes <iostream> and <string>.

std::string s = "a\tb\n";

std::cout << s.size();

What output does the program produce?

a) 6

b) 5

c) 4

d) 2

02. Four lines mentioning the same function appear in a program.

Which one invokes it?

a) total = area(3, 4);

b) int area(int w, int h);

c) int area(int w, int h) { return w * h; }

d) extern int area(int, int);

03. A student proposes four ways of declaring the entry point of a C++ program.

Which one is not a valid form of main()?

a) int main()

b) void main()

c) int main(int argc, char *argv[])

d) int main(void)

04. Two pointer declarations differ only in where const appears.

int n = 0, m = 0;

const int *p = &n;

int *const q = &n;

Which statement describes them correctly?

a) p may be written through but not reseated; q may be reseated but not written through

b) Both forbid reseating and both forbid writing through, so the two are equivalent

c) p may be reseated but not written through; q may be written through but not reseated

d) q is rejected, because const may not follow the star in a declaration

05. A hierarchy defines the two classes below, and a caller writes Stream *s = &file; s->flush();.

class Stream { public: void flush(); };

class FileStream : public Stream { public: void flush(); };

Which function runs, and why?

a) FileStream::flush, because the pointer addresses a FileStream object

b) Neither, because the two declarations conflict and the program is rejected

c) FileStream::flush, because a derived function always hides and replaces the base one

d) Stream::flush, because a non-virtual call is always resolved from the pointer's declared type

06. Two std::string objects are compared with the member function a.compare(b).

What does the call return when the two strings are equal?

a) 1

b) 0

c) true

d) The length of the common prefix

07. Four literals are written for the same intended value.

Which literal does not denote 255?

a) 0xFF

b) 0377

c) 0255

d) 255

08. Assume <iostream> is included and that the lines below execute in order.

for (int i = 0; i < 6; ++i) {

if (i % 2 == 0) continue;

std::cout << i;

}

What does the fragment print?

a) 135

b) 024

c) 13

d) Nothing, because continue in a for loop skips the increment and the loop never advances

09. The statements below run inside main(), with <iostream> included.

int a = 1, b = 2, c = 3;

a = b = c;

std::cout << a << b << c;

What does the fragment print?

a) 133

b) 333

c) 123

d) 223

10. Consider the complete program below.

#include <iostream>

#define LEVEL 2

int main() {

#if LEVEL > 2

std::cout << "high";

#elif LEVEL > 0

std::cout << "mid";

#else

std::cout << "low";

#endif

return 0;

}

What does the program print?

a) mid

b) high

c) low

d) midlow
