Problem Statement
Write a c program to convert the binary digits to decimal number.
Solution
#include<stdio.h>
int main()
{
int n,rem,base=1,decimal=0;
scanf("%d",&n);
while(n>0)
{
rem=n%10;
decimal=decimal+rem*base;
n=n/10;
base=base*2;
}
printf("%d",decimal);
}
Input
1111
Output
15
Program Explanation
- In this c program, we are going to see how to convert binary digits into decimal number.
- Here we declare header file stdio.h for input and output standard function files and integer variables as n, rem, base and decimal.
- Using scanf function we are accepting the input binary digits.
- Then using while loop converting the binary digits into decimal number stored in the decimal variable.
- Printing the final result value of this program using printf function.
