C Exercises: Convert decimal to binary
C Function : Exercise-6 with Solution
Write a program in C to convert decimal number to binary number using the function.
Pictorial Presentation:
Sample Solution:
C Code:
#include<stdio.h>
long toBin(int);
int main()
{
long bno;
int dno;
printf("\n\n Function : convert decimal to binary :\n");
printf("-------------------------------------------\n");
printf(" Input any decimal number : ");
scanf("%d",&dno);
bno = toBin(dno);
printf("\n The Binary value is : %ld\n\n",bno);
return 0;
}
long toBin(int dno)
{
long bno=0,remainder,f=1;
while(dno != 0)
{
remainder = dno % 2;
bno = bno + remainder * f;
f = f * 10;
dno = dno / 2;
}
return bno;
}
Sample Output:
Function : convert decimal to binary : ------------------------------------------- Input any decimal number : 65 The Binary value is : 1000001

C Programming: Tips of the Day
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().
