![I am try to create a program that takes a user typed MIPS instruction (ex: add $6 $8 $10) then
turns that into its binary value.
but for some reason it will not work correctly. Also the code is not fully done but it shouldn't
effect anything

printf("Enter MIPS: ");
//Asks for the MIPS statement even with spaces
fgets(str, 50, stdin);
sscanf( str, "%s %s %s %s", op, rs, rt, rd );
//For R type of instructions
