Question 1

Where is the storage for the "hello" string literal allocated in memory when this program is run?

#include int main(void) { char * p = "hello"; printf("%s ", p); return 0; }

Question 1 options:

A	No memory is allocated to "hello".
B	On the heap.
C	Somewhere else.
D	On the stack.

Question 2

Where is the memory for array s allocated?

#include int main(void) { char s[] = "hello"; printf("%s ", s); return 0; }

Question 2 options:

A	On the stack.
B	Somewhere else.
C	On the heap.

Question 3

Is this initialization correct?

char c = "b";

Question 3 options:

A	True
B	False

Question 4

What does the following code print?

#include int main(void) { char c = '0'; if (c) printf("yes "); else printf("no "); return 0; }

Question 4 options:

A	None of the above.
B	It prints "no."
C	It crashes.
D	It does not compile.
E	It prints "yes."
F	The standard does not define what the program should print.

Question 5

What does the following code print (on a 32-bit machine)?

#include void printSize(char * p) { printf("%zu ", sizeof(p)); } int main(void) { char * p = NULL; printSize(p); return 0; }

Question 5 options:

A	It crashes.
B	It does not compile.
C	1
D	4

Question 6

What's the value of sizeof(char)?

Question 6 options:

A	8
B	It depends on the compiler and operating system, but it's at least 8.
C	1
D	It's either 4 on a 32-bit machine or 8 a 64-bit machine.

Question 7

What happens when you compile and run this program? (To print the return value you can use echo $? in the command-line window right after running the program.)

#include int main(void) { char c = NULL; return c != '\0'; } 

Question 7 options:

A	It returns -1.
B	It compiles just fine, even with -Wall -Wextra.
C	It produces a compilation error.
D	It crashes.
E	It produces a compilation warning, but then it returns 0.

Question 8

Consider the following program.

/* Return the first character of a string. * If passed a NULL pointer or an empty * string, return '\0'. */ char firstChar(char const * str) { if (!str) return '\0'; return *str; } 

Does it handle the empty string input according to the specification?

Question 8 options:

A	True
B	False

Question 9

What does the following program print when executed?

#include int main(void) { char c[] = "3G"; c[0]++; printf("%s ", c); return 0; } 

Question 9 options:

A	4G
B	G
C	It prints nothing because it crashes when it tries to modify read-only memory.
D	3H

Question 10

What does the following program print when run?

#include int main(void) { char str[] = "complement"; char * p = str; p[sizeof(str)-6] = 'i'; printf("That's quite a %s! ", str); return 0; } 

Question 10 options:

A	That's quite a compiement!
B	That's quite a complement!
C	The program does not compile.
D	That's quite a compliment!
