Question
1. After this line of code executes what will be the value of “result”? int result = 10 % 5;
2. After this line of code executes what will be the value of “result”?
int result = 20 + 5 * 2 * 3 / 10 – 6 + 12 / 4;
3. What will be the value of “sumtotal” when this code is executed?
int n1 = 3, n2 = 6, n3 = 2, sumtotal = 4;
if (n1 ! = 4)
sumtotal -= n3;
else if (n3 <= 5)
sumtotal = ++n2;
else sumtotal += n1;
4. What is the final value of “y” after this for loop is finished? for (y = 3; y<=14; y+=5)
5. What will the following C code print out?
int x = 7, y = 5;
if (x > 5)
if (y > 5)
printf(“x and y are > 5”);
else
printf(“x is <=5”);
a) “x and y are > 5”
b) “x is <=5”
c) nothing will be printed
6. In which of the following is “y” not equal to 5 after execution? X is equal to 4.
a) y = ++x; b) y = x = 5; c) y = 5; d) y = x++;
Examine the following code and answer questions 7 below. IGNORE COMPILE ERRORS.
int j = 0;
for (j = 0; j <= 9; j++)
{ printf( “%d”, 1 + ( rand() % 5 )); }
7. What are the POSSIBLE range of numbers that will be printed by the “printf()” statement above?
8. Examine the following code. What will be the output from the “printf()” statement below?
#define S_SIZE 10
char s[10] = { ‘g’ , ’o’ , ’m’ , ’i’ , ’z’ , ’z’ , ’o’ , ’u’ };
int j = 0;
for (j = S_SIZE -2; j > 4; j--) { printf( “%c”, s[j]); }
Using the definitions below (IGNORE ALL COMPILE ERRORS):
char s1 [ 50 ] = “JACK”, s2 [ 50 ]=”FRED”;
