Text: Read the following C program and answer questions 6) to 7)
int func(int arr[], int n) {
int result = 0, i = 0;
for (i = 0; i < n; i++)
result ^= arr[i];
return result;
}
6) What value will be returned if the function call is func(arr, 5) while the passed array has elements 1, 2, 2, 3, and 3 in it?
(a) 1
(b) 2
(c) 5
(d) None of the above
7) What does the function func do?
(a) Get the first element from the array.
(b) Count the number of elements in the array.
(c) Remove pairs of elements with the same value from the array.
(d) None of the above
8) Assume 'A' has an ASCII code 65, i is an int type variable and has a value of 2, c is a char type variable. After the execution of c = 'A' + 011, the value of c is:
(a) 'D'
(b) 68
(c) 'C'
(d) None of the above
9) Which statement below is not equivalent to the other two (assuming that the loop bodies are the same)?
(a) for (n = 0; n < 10; n++)
(b) for (n = 0; n < 10; ++n)
(c) for (n = 1; n <= 10; n = n + 1)
(d) for (n = 0; n++ < 10; )
10) Assume that a program contains the following declarations:
char c = 65;
int i = 2;
double d = 5.5;
Give the data type of the following expressions:
(1) (c + i) / d
(2) d - c
(3) c * i
(a) double, double, int
(b) int, double, int
(c) int, double, char
(d) None of the above
