Question

Write an assembly language program to convert hexadecimal number to decimal number for the n numbers in an array

Answer 1

// C++ program to convert a decimal

// number to hexadecimal number

 

#include<iostream>

using namespace std;

 

// function to convert decimal to hexadecimal

void decToHexa(int n)

{  

    // char array to store hexadecimal number

    char hexaDeciNum[100];

     

    // counter for hexadecimal number array

    int i = 0;

    while(n!=0)

    {  

        // temporary variable to store remainder

        int temp  = 0;

         

        // storing remainder in temp variable.

        temp = n % 16;

         

        // check if temp < 10

        if(temp < 10)

        {

            hexaDeciNum[i] = temp + 48;

            i++;

        }

        else

        {

            hexaDeciNum[i] = temp + 55;

            i++;

        }

         

        n = n/16;

    }

     

    // printing hexadecimal number array in reverse order

    for(int j=i-1; j>=0; j--)

        cout << hexaDeciNum[j];

}

 

// Driver program to test above function

int main()

{

    int n = 2545;

     

    decToHexa(n);
