Programa para convertir decimal a hexadecimal

Dado un número decimal como entrada, necesitamos escribir un programa para convertir el número decimal dado en un número hexadecimal equivalente. es decir, convertir el número con valor base 10 al valor base 16.

Los números hexadecimales utilizan 16 valores para representar un número. Los números del 0 al 9 se expresan con dígitos del 0 al 9 y del 10 al 15 con caracteres de la A a la F.

// 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);
 
    return 0;
}
