#include <iostream> #include <math.h> using namespace std; int main() { int num, temp, rem, oct = 0, i = 0; cout << "Enter an octal number : "; cin >> num; temp = num; while(temp != 0) { rem = temp % 10; oct += rem * pow(8, i++); temp = temp / 10; } cout << "\nDecimal equivalent of " << num << " is : " << oct; return 0; } |
Output
Enter an octal number :
7
Decimal equivalent of 7 is 7.
