Question

An integer array of size 10 is declared in a C program. The memory location of the first byte of the array is 1000. What will be the location of the 8th element of the array? (Assume integer takes 4 bytes of memory and the element stored at 1000 is identified as 1st element).
a) 1028
b) 1032
c) 1024
d) 1036

Answer 1

Concept

• An array is a collection of memory locations, or "boxes," each of which contains a single piece of data and which has the same name as the others.
• An array is a group of related data pieces kept in close proximity to one another in memory.
• The sole way to retrieve each data piece directly is by using its index number, making it the most basic data structure.

Explanation

• first element location = 1000
• 2nd element location = 1004
• like wise...8th element location = 1000+28=1028 that is; 1000+(N-1)*4 = 1000+(8-1)*4 so it will be 1028

Hence the  the location of the 8th element of the array will be 1028 which is option (A)

Answer 2

Answer:

The  the location of the 8th element of the array will be 1028 which is option (A)

Explanation:

• An array is a collection of memory locations, or "boxes," each of which contains a single piece of data and  has the same name as  others.

• it is a group of related data pieces kept in close proximity to one another in memory.

• The sole way to retrieve each data piece directly is by using its index number, making it the most basic data structure.

1st element location = 1000

2nd element location = 1004

like wise...8th element location = 1000+28=1028 that is; 1000+(N-1)x4 = 1000+(8-1)x4 so it will be 1028

Hence the  the location of the 8th element of the array will be 1028 which is option (A)
