VTU C PROGRAMMING LAB – 15] Write a Program to Convert a Binary Number into a Decimal Number.
15. C PROGRAMMING – Algorithm
- Step-1: Start
- Step-2: Read the binary number value
- Step-3: Call the function find by passing arguments
- Step-4: Check if number entered is zero than return 0 otherwise compute using formula-
- ( pow ( 2, count ) * ( x % 10 ) + find ( x /10 , count + 1 ) )
- Step-5: Repeat the step-4 until recursive condition find becomes false
- Step-6: Return the result of converted number
- Step-7: Stop

C PROGRAMMING -15 Program source code
#include <stdio.h>
#include <math.h>
int find(int x, int count)
{
if (x == 0)
return 0;
else
return(pow(2, count) * (x%10 ) + find(x/10 ,count+1));
}
void main()
{
int binary;
printf("Enter a Binary number");
scanf ("%d",&binary);
printf(" The decimal value for binary %d is",binary);
printf("%d", find(binary,0));
}
Output
Enter a Binary number
1010
The decimal value for binary number 1010 is 10
