Write a c program to convert binary number to decimal number

C code for binary to decimal conversion:

#include<stdio.h>

int main(){

   

    long int binaryNumber,decimalNumber=0,j=1,remainder;

    printf("Enter any number any binary number: ");

    scanf("%ld",&binaryNumber);

    while(binaryNumber!=0){

         remainder=binaryNumber%10;

        decimalNumber=decimalNumber+remainder*j;

        j=j*2;

        binaryNumber=binaryNumber/10;

    }

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

    return 0;

}

Sample output:

Enter any number any binary number: 1101

Equivalent decimal value: 13
