Write a C Program to Convert Binary Number to Decimal Number

 #include <stdio.h>
 #include<math.h>
 int binaryToDecimal(long binarynum)
{
    int decimalnum = 0, temp = 0, remainder;
    while (binarynum!=0)



    
    {
        remainder = binarynum % 10;
        binarynum = binarynum / 10;
        decimalnum = decimalnum + remainder*pow(2,temp);
        temp++;
    }
    return decimalnum;
}

int main()
{
    long binarynum;
    printf("Enter a binary number: ");
    scanf("%ld", &binarynum);

    printf("Equivalent decimal number is: %d", binaryToDecimal(binarynum));
    return 0;
}



          

Output:

 Enter a binary number: 0101
 Equivalent decimal number is: 5
