14. Let an array A is defined as int A[3][5]={1..5,6..10,11..15}, where an integer takes 4 bytes of memory. If the base address of A is 1000 then the memory location of A[1][4] will be:
Correct : A
Explanation:
In a 2D array like A[3][5], the memory is allocated in a contiguous manner. The elements are stored row-wise. The formula to calculate the address of an element in a 2D array is given by:
Address of A[i][j]=Base Address+(i x Number of Columns+j) x Size of Data Type
Given that the base address of A is 1000 and each integer takes 4 bytes, and you want to find the address of A[1][4]:
Address of A[1][4]=1000+(1 x 5+4) x 4= 1036.

19. The correct option for Primary Key and Unique Key is :
Correct : C
Explanation:A primary key is a column or set of columns in a relational database table that uniquely identifies each record. A relational database can only have one primary key. A table can only have one primary key. A unique key is a set of one or more columns in a table that identifies a record in a database table. Unique keys are similar to primary keys, but they can only accept one null value for a table column.
20. Find the decimal equivalent of binary number :
(1101.0111)2=(?)10
Correct : B
Explanation:
To convert the binary number1101.0111 2< to decimal, we can separate the whole number part from the fractional part and convert each part individually.
Whole number : 1101 2 =1x2 3 +1x2 2 +0x2 1 +1x2 0 =8+4+1=13
fractional part : 0.0111 2 =0x2 - 1 +1x2 - 2 +1x2 - 3 +1x2 - 4 =0.25+0.125+0.0625 = 0.4375
1101.0111 2 =13+0.4375=13.4375
