Assembly language program to add three numbers

In the first program, we have been implemented the addition of two numbers. In this, we demonstrate the addition of D numbers. Firstly, the resulting sum of the first 2 numbers will be stored. To perform this sum, the third number will be added.

This process will be repeated until all the numbers of series are added. A conditional jump instruction will be utilized to implement the counter checking logic. The comments describe the purpose of each instruction.

The use of statement ORG H in this program is not necessary. We have used this statement here only to explain the way to use it. It will not affect the result at all. When a program loaded into the memory whatever is the address assigned for CODE, the executable code begin at the offset address H due to the above statement.

Same to DW, the directive DB reserves space for the list of 8-bit numbers in the series. The process for entering the program, coding and execution has already been discussed. ROR : Rotate Right without Carry: This instruction rotates the contents of destination operand to the bit-wise right either by one or by the count specified in register CL, exclud.

By default type of numbering system is Decimal. If you do not specify any letter then the number is understood to be Decimal By default. Data Segment, 2. Code Segment, 3. Stack Segment, and 4.

You also don't need to terminate a statement with a semicolon in assembly. What you're doing is starting an empty comment. It's harmless, but confusing. The cmp instruction doesn't write to either of its operands, so you're basically setting the flags for ax-bx, then overwriting the flags with ax-cx. Whatever ax was originally is printed, so your algorithm won't work as you intend.

You need to either print the correct register, or move the correct value to AX, and that means a conditional test, which means a jump:. N fractal.
