int [] arrayInt={3,54,90,22,32};
To print the last element in the arrayInt you will write:
a.
System.out.println(arrayInt[5]);
b.
System.out.println(arrayInt[0]);
c.
System.out.println(arrayInt[length]);
d.
System.out.println(arrayInt[4]);
В.width; }
{ t = B.type; w =
{ T.type = C.type; T.width = C.width; }
T → B
C
В > int
{ B.type = integer; B.width
4; }
В — foat
{ B.type = float; B.width =
8; }
{ C.type = t; C.width
= w; }
C - [ num] C1 = array(num. value, C1.type);
{ C.type
C.width
= num. value x C1. width; }
int A[3] [4]={{ 4, 6, 7, 9},{ 1, 3, 4, 3},{-5, 6, 7, 2}};
int sum, row, col;
sum
= 0;
for (col=0;col<=3;i++)
sum+=A[0] [col];
what is the value of sum calculated
the number of elements on row 0
the total addition of elements on row 0
the total addition of first 3 elements on row 0
the total addition of all the elements
