1) What is the range of values that can be stored by int datatype in C?

• -(2^31) to (2^31) - 1

• -256 to 255

• -(2^63) to (2^63)-1

• O to (2^31) - 1

2) How is an array initialized in C language?

• int a[3] = {1, 2, 3};

• int a = {1, 2, 3};

• int a[] = new int[3]

• int a(3) = [1, 2, 3];

3) What is the output of the following code snippet?

#include <stdio.h>

int main()

{ int a[] = {1, 2, 3, 4};

int sum = 0;

for(int i = 0; i < 4; i++)

{

sum += a[i];

}

printf("%d", sum);

return 0;

}

• 1

• 4

• 20

4) How are String represented in memory in C?

• An array of characters.

• The object of some class.

• Same as other primitive data types.

• LinkedList of characters.

5) How is the 3rd element in an array accessed based on pointer notation?
