Source Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

#include <iostream> #include <cmath> using namespace std; int octalToDecimal(int octalNumber); int main() { int octalNumber; cout << "Enter an octal number: "; cin >> octalNumber; cout << octalNumber << " in octal = " << octalToDecimal(octalNumber) << " in decimal"; return 0; } // Function to convert octal number to decimal int octalToDecimal(int octalNumber) { int decimalNumber = 0, i = 0, rem; while (octalNumber != 0) { rem = octalNumber % 10; octalNumber /= 10; decimalNumber += rem * pow(8, i); ++i; } return decimalNumber; }

Enter an octal number: 2341
2341 in octal = 1249 in decimal
