4 Find out what kind of mathematical operation the following assembly program is trying to achieve and then write simple C codes to implement the same function. Assembly Program AREA factorial, CODE, READONLY EXPORT _main ENTRY _main PROC MOV r0, #1 ; r = result MOV r1, #5 ; r1 = n MOV r2, #1 ; r2 = i = 1 loop CMP r2, r1 BGT stop MULS ro, r2, ro; ADD r2, r2, #31 ; 3 compare i and n ; if in, stop result i i++ B loop stop B stop ENDP END C Program
