Question

An integer array a [30][40] is stored along the column in the memory. If the element a[20][25] is stored at 50000, find out the location of a[25][30].

Answer 1

Total number of rows= 30

Total size= 2 bytes

Base Address= 26500

LOC (P[I][J]) = BaseAddress+((I-LBR) + (J-LBC) * R)*W

Assuming Lower Bound of Row(LBR)=0

Lower Bound of Column(LBC)=0

Total number of Rows(R)=30

Size of each element(W)=2

LOC(P[20][10])= 26500 +((20-0)+(10-0)*30)*2

LOC(P[20][10])= 26500 +640

LOC(P[20][10])= 27140
