# Decimal to Hexadecimal Conversion

“** Decimal to Hexadecimal Conversion**” is a one of the classic programming problem exercise for beginners. Here, we are given a Decimal Number, entered by user and our task is to write a program to convert the given Decimal Number to its equivalent Hexadecimal Number.

Hexadecimal Numbers uses 16 values to represent the number. Numbers from __0-9 are expressed by digits 0-9 and 10-15 are represented by characters from A – F__**. **

**Examples (Decimal to Hexadecimal Conversion):**

Decimal = 15 Hexadecimal = A Decimal = 78 Hexadecimal = 4E

The steps required for decimal to hexadecimal conversion are as follows:

- Initialize an empty string which will store hexadecimal number.
- Store the remainder when the decimal number is divisible by 16.
- If the remainder is less than 10, then convert the remainder number into character by (remainder + 48) and insert it to hexadecimal string at the front.
- Else if the remainder is greater than 9, then convert the remainder number into character by (remainder + 55) and insert it to hexadecimal string at the front.
- Divide the decimal number by 16.
- Repeat the steps from 2 to 5 until decimal number is greater than 0.
- Print the Hexadecimal number.

**C++ Program for Decimal to Hexadecimal Conversion is as follows:**

/* C++ Program for Decimal to Hexadecimal Conversion */ #include<bits/stdc++.h> using namespace std; int main() { /* Scan the Decimal Number */ int Decimal; cout<<"Enter the Decimal Number: "; cin>>Decimal; /* Converting Decimal to Hexadecimal */ string Hexadecimal; int temp = Decimal; while(temp!=0) { int remainder = temp % 16; if(remainder >=0 && remainder <=9) { char ch = remainder + 48; Hexadecimal = ch + Hexadecimal; } else { char ch = remainder + 55; Hexadecimal = ch + Hexadecimal; } temp = temp / 16; } /*Printing the result */ cout<<"The Hexadecimal of "<<Decimal<<" is "<<Hexadecimal; }

Enter the Decimal Number: 78 The Hexadecimal of 78 is 4EOUTPUT:
