Which software is used for assembly language programming?

These include MASM (Macro Assembler from Microsoft), TASM (Turbo Assembler from Borland), NASM (Netwide Assembler for both Windows and Linux), and GNU assembler distributed by the free software foundation.

How do you show 2 digit numbers in assembly language?

1. AAM ; nice trick instruction divides by 10.
2. ; result AH=high decimal digit, AL=low decimal digit.
3. ADD AX,03030h ; adds a “0” ASCII digit to both digits.
4. ; now AX contains the 2 decimal ASCII digits, you can do with them as you please, display on the screen, save, etc.

How do you output a string?

If we want to do a string output in C stored in memory and we want to output it as it is, then we can use the printf() function. This function, like scanf() uses the access specifier %s to output strings. The complete syntax for this method is: printf(“%s”, char *s);

How do we write a program in assembly language?

In assembly language, we use symbolic names to denote addresses and data. A number of such examples are dealt with in the successive chapters. Thus writing a program in assembly language has advantages over writing the same in a machine language. Assembly language programs are platform dependent.

How is assembler written?

There’s nothing special about how an assembler is written. All it does is parse an assembly syntax and spit out machine code for a particular architecture. If your preferred programming language can read text and write binary, you can create an assembler with it.
