Write a C++ program to convert a Decimal number to its corresponding Hexadecimal number.

Write a C++ program to convert a Decimal number to its corresponding Hexadecimal number.

Program Code:

#include<iostream>

using namespace std;

int main()

{

long int deci, rem, q;

char hexa[100];

int i=1, j, temp;

cout<<"Enter any decimal number : ";

cin>>deci;

cout<<endl;

q = deci;

while(q != 0)

{

temp = q % 16;

if(temp < 10)

{

temp = temp + 48;

}

else

{

temp = temp + 55;

}

hexa[i++] = temp;

q = q / 16;

}

cout<<"Equivalent hexadecimal value of "<<deci<<" is : ";

for(j=i-1; j>0; j--)

{

cout<<hexa[j];

}

return 0;

} 

The program output is tested on www.jdoodle.com

Output:

Enter any decimal number : 45

Equivalent hexadecimal value of 45 is : 2D
