An integer is a whole number with no fractional part. In assembler, the variables are created by data allocation directives. Assembler declaration of integer variable assigns a label to a memory space allocated for the integer.
The atoi() function converts a character string to an integer value. The input string is a sequence of characters that can be interpreted as a numeric value of the specified return type. The function stops reading the input string at the first character that it cannot recognize as part of a number.
When I add two values in 16 bit assembly, what is the best way to print the result to console?
At the moment I have this code:
;;---CODE START---;;
mov ax, 1 ;put 1 into ax
add ax, 2 ; add 2 to ax current value
mov ah,2 ; 2 is the function number of output char in the DOS Services.
mov dl, ax ; DL takes the value.
int 21h ; calls DOS Services
mov ah,4Ch ; 4Ch is the function number for exit program in DOS Services.
int 21h ; function 4Ch doesn't care about anything in the registers.
;;---CODE END---;;
I think that dl value should be in ASCII code, but I'm not sure how to convert ax value after addition into ASCII.
