Binary to Decimal Conversion in C

✅ Binary to Decimal Conversion in C

#include<stdio.h>
int main( )
{
    int num, decimal = 0, remainder, j = 1;
    printf("Enter binary number:\n");
    scanf("%d", &num);
    while(num != 0)
    {
        remainder = num % 10;
        decimal = decimal + remainder * j;
        j = j * 2;
        num = num / 10;
    }
    printf("The decimal value is %d\n", decimal);
}
  

📘 Explanation:

This program converts a binary number (input as an integer) into its decimal equivalent.
- It extracts each digit (right to left) using modulus and multiplies it by powers of 2.
- The value is added to a `decimal` variable.
- `%d` is used in printf to display the result in decimal format.

🧾 Sample Output:

Enter binary number:
1010
The decimal value is 10
