C Exercises: Convert a binary number into a decimal using math function
C For Loop: Exercise-46 with Solution
Write a program in C to convert a binary number into a decimal number using math function.
Pictorial Presentation:
Sample Solution:
C Code:
#include <stdio.h>
#include <math.h>
void main()
{ int n1, n;
int dec=0,i=0,j,d;
printf("\n\nConvert Binary to Decimal:\n ");
printf("-------------------------\n");
printf("Input the binary number :");
scanf("%d",&n);
n1=n;
while(n!=0)
{ d = n % 10;
dec=dec+d*pow(2,i);
n=n/10;
i++;
}
printf("\nThe Binary Number : %d\nThe equivalent Decimal Number is : %d\n\n",n1,dec);
}
Sample Output:
Convert Binary to Decimal: ------------------------- Input the binary number :1010100 The Binary Number : 1010100 The equivalent Decimal Number is : 84

Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
