WAP in C++ to Convert Octal number to a hexadecimal

The Program in C++ to Convert octal number to a hexadecimal number is given below:

``````#include <iostream>
#include <math.h>
using namespace std;

int main() {
int decimal = 0, octal, remainder, product = 0;
cout <<"Hello Codeauri Family,Enter an octal number to get converted into hexadecimal number:\n";
cin>>octal;

// convert octal to decimal
while(octal != 0) {
decimal += (octal%10) * pow(8,product);
++product;
octal /= 10;
}

while (decimal != 0) {
remainder = decimal % 16;
if (remainder < 10) {
} else {
}
decimal /= 16;
}

cout << "Well,the number in the hexadecimal form is: " << hexadecimal;
return 0;
}
``````

Output:

Hello Codeauri Family,Enter an octal number to get converted into hexadecimal number:
5
Well,the number in the hexadecimal form is: 5

Pro-Tips💡

This program works by first converting the input octal number to a decimal number using mathematical operations,

and then converting the decimal number to a hexadecimal number using a similar process.

The user is prompted to input an octal number, and the final hexadecimal number is outputted to the user.

The program uses remainder and a while loop to successively find the least significant digit of the decimal number and converts the digit to its corresponding hexadecimal digit.
