c programming Convert Binary Number to Decimal

Examples

// Convert Binary Number to Decimal #include <stdio.h> #include <math.h> int convertBinaryToDecimal(long long n); int main() { long long n; printf("Enter a binary number: "); scanf("%lld", &n); printf("%lld in binary = %d in decimal", n, convertBinaryToDecimal(n)); return 0; } int convertBinaryToDecimal(long long n) { int decimalNumber = 0, i = 0, remainder; while (n!=0) { remainder = n%10; n /= 10; decimalNumber += remainder*pow(2,i); ++i; } return decimalNumber; }
Output
Enter a binary number: 110110111 110110111 in binary = 439
