Consider the two dimensional array A:
int A[ ] [ ] = new int  
where A  is at location 400, in a paged system with pages of size 400. A small process is in page 0 (locations 0 to 399) for manipulating the matrix; thus, every instruction fetch will be from page 0.
For three page frames, how many page faults are generated by the following array-initialization loops, using LRU replacement, and assuming page frame 1 has the process in it, and the other two are initially empty:
My answer:I workout 625 faults for above.Anyone correct me if i am wrong.Quote:
for (int j = 0; j < 100; j++)
for (int i = 0; i < 100; i++)
A[i][j] = 0;
