This is a simple example that adds two integers, using 32-bit registers EAX and EBX:
#include <iostream> using namespace std; int main() { int n, m, Result; // How to perform an addition on two integers // Result = n + m __asm { MOV n, 202 // Store 202 in n MOV m, 125 // Store 125 in m MOV EAX, n // Put the value of n in 32-bit register EAX MOV EBX, m // Put the value of m in 32-bit register EBX ADD EAX, EBX // Add the contents of EBX to the contents of EAX // and store the result in register EAX MOV Result, EAX // Retrieve the contents of EAX and put it in Result } cout << "n = " << n << endl; cout << "m = " << m << endl; cout << "Result: " << Result << "\n\n"; return 0; } |
This would produce:
n = 202 m = 125 Result: 327 Press any key to continue...
