Explanation:
oid changeCase (char char_array[], int array_size ) {
__asm{
// BEGIN YOUR CODE HERE
mov eax, char_array; //eax is base image
mov edi, 0;
readArray:
cmp edi, array_size;
jge exit;
mov ebx, edi; //using ebx as offset
shl ebx, 2;
mov cl, [eax + ebx]; //using ecx to be the storage register
check:
//working on it
cmp cl, 0x41; //check if cl is <= than ASCII value 65 (A)
jl next_indx;
cmp cl, 0x7A; //check if cl is >= than ASCII value 122 (z)
jg next_indx;
cmp cl, 'a';
jl convert_down;
jge convert_up;
convert_down:
or cl, 0x20; //make it lowercase
jmp write;
convert_up:
and cl, 0x20; //make it uppercase
jmp write;
write:
mov byte ptr [eax + ebx], cl //slight funky town issue here,
next_indx:
inc edi;
exit:
cmp edi, array_size;
jl readArray;
mov char_array, eax;
// END YOUR CODE HERE
}
}
