Here 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**

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*

RehmanI need a C code to convert Binary to BCD and vice versa. But code should be with explanation as I am new to programming. Please need your help.
