AIM

To write an assembly language program for finding the largest and smallest element of an array using 8085.

ALGORITHM

• Maximum number is stored in B register and Minimum number is stored in C register.

• Load counter in D register.

• Load starting element in accumulator, B and C register.

• Compare accumulator with B register.

• If carry flag is not set then transfer contents of accumulator to B. Else, compare accumulator with C register. If carry flag is set, transfer content of accumulator to C.

ALGORITHM

• Decrement D register.

• If D>0 take next element in accumulator and go to point 4.

• If D=0,store B and C register in memory.

• End of the program.
