Convert Binary to Decimal in C

ere you will get program to convert binary to decimal in C.
We can obtain a decimal number by multiplying each digit of binary number with power of 2 and adding each multiplication result. The power starts from 0 and goes to n-1 where n is the total number of digits in binary number.
Below is the program to implement this in C.

Convert Binary to Decimal in C

#include<stdio.h> #include<math.h> int main() { long int i,n,x=0,a; printf("Enter any binary number: "); scanf("%ld",&n); printf("\nThe decimal conversion of %ld is ",n); for(i=0;n!=0;++i) { a=n%10; x=(a)*(pow(2,i))+x; n=n/10; } printf("%ld",x); return 0; }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

#include<stdio.h> #include<math.h>   int main() {     long int i,n,x=0,a;     printf("Enter any binary number: ");     scanf("%ld",&n);     printf("\nThe decimal conversion of %ld is ",n);          for(i=0;n!=0;++i)     {         a=n%10;         x=(a)*(pow(2,i))+x;         n=n/10;     }          printf("%ld",x);          return 0;     }

Output
Enter any binary number: 111
The decimal conversion of 111 is 7
