#include<stdio.h>

#include<math.h>

int main(){

   

    long int octal,decimal =0;

    int i=0;

    printf("Enter any octal number: ");

    scanf("%ld",&octal);

    while(octal!=0){

         decimal = decimal + (octal % 10) * pow(8,i++);

         octal = octal/10;

    }

    printf("Equivalent decimal value: %ld",decimal);

   return 0;

}
