Mix (C++ and Assembly) Program to Convert BCD Number into Binary Format
This post demonstrates how to convert a Binary Coded Decimal (BCD) number into its binary equivalent using inline assembly within a C++ program. The conversion is done by isolating and processing each BCD digit and calculating its decimal equivalent.

This post explores how to reverse an array of integers using inline assembly within a C++ program. The program swaps elements from the start and end of the array using low-level assembly instructions.
#include<iostream.h>
#include<conio.h>
void main()
{
int nos[5], x, y;
cout << "\n Enter 5 numbers:";
int i, j;
for(i = 0; i < 5; i++)
{
cin >> nos[i];
}
for(i = 0, j = 4; i < 3; i++, j--)
{
x = nos[i];
y = nos[j];
_asm{
mov ax, x
mov bx, y
mov cx, ax
mov ax, bx
mov bx, cx
mov x, ax
mov y, bx
}
nos[i] = x;
nos[j] = y;
}
cout << "\n Reverse:";
for(i = 0; i < 5; i++)
{
cout << nos[i] << " ";
}
getch();
}
Mix (C++ and Assembly) Program to Check if String is Palindrome or not
This C++ program checks whether a given array of five integers is a palindrome (i.e., reads the same forwards and backwards) using inline 8086 assembly instructions. It utilizes basic comparison instructions and control flow to determine equality between symmetric elements.
#include<iostream.h>
#include<conio.h>
void main()
{
int nos[5], x, y;
cout << "\n Enter 5 numbers:";
int i, j;
for (i = 0; i < 5; i++) {
cin >> nos[i];
}
for (i = 0, j = 4; i < 3; i++, j--) {
x = nos[i];
y = nos[j];
_asm {
mov ax, x
mov bx, y
cmp ax, bx
jnz no
}
}
cout << "\n Array is Palindrome.";
goto end;
no:
cout << "\n Array is not palindrome.";
end:
getch();
}
Mix (C++ and Assembly) Program to Search an Element in an Array
This C++ program demonstrates how to search for a specific element within an array of 10 integers using 8086 assembly instructions embedded inline. The program uses the cmp and jz instructions to perform the comparison and detect a match.
#include<iostream.h>
#include<conio.h>
void main()
{
int nos[10], j, t;
int i, p;
cout << "\n Enter 10 numbers:";
for (i = 0; i < 10; i++) {
cin >> nos[i];
}
cout << "\n Enter number to be searched:";
cin >> j;
for (i = 0; i < 10; i++) {
p = i;
t = nos[i];
_asm {
mov ax, t // Load current array element
mov bx, j // Load number to be searched
cmp ax, bx // Compare current element with target
jz out // If match found, jump to output
}
}
cout << "\n No is not found.";
goto end;
out:
cout << "\n Number is found at " << p + 1 << " th position";
end:
getch();
}
Mix (C++ and Assembly) Program to Add Two 16 bit Numbers
While high-level languages like C++ are well known for abstracting away low-level operations, sometimes it’s beneficial to peek under the hood to see how things really work at the machine level. In this post, we’ll explore a simple C++ program that incorporates inline assembly to add two 16-bit numbers.
#include<iostream.h>
#include<conio.h>
#include<stdio.h>
void main()
{
clrscr();
int a,b,c;
cout<<"Enter First Number:";
cin>>a;
cout<<"Enter Second Number:";
cin>>b;
asm mov ax, a // Move first number into AX
asm mov bx, b // Move second number into BX
asm add ax, bx // Add BX to AX (binary addition)
asm mov c, ax // Move result into variable 'c'
cout<<"Result:";
cout<<c;
getch();
}
Mix (C++ and Assembly) Program to Add Two 16 bit Numbers (With DAA)
While high-level programming languages like C++ make arithmetic operations incredibly simple, delving into inline assembly offers valuable insights into how the CPU processes instructions under the hood. Hence in this post, we’ll walk through a simple program that uses both C++ and inline assembly to add two integer values. Additionally, we will carry out decimal adjust after addition.
