c program to convert octal to equivalent decimal number

// C Program to Convert Octal to Decimal
#include <stdio.h>
#include <math.h>
int main()
{
long int octal, decimal = 0;
int i = 0;
printf(“Enter 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;
}



Output:

Enter octal number: 27
Equivalent decimal value: 23
