C programs

 -Fibonacci program
This program prints the Fibonacci series

#include<stdio.h>
#include<conio.h>
void main(void)
{
int i,j,k,n;
clrscr();
i=0;
j=1;
printf("%d %d ",i,j);
for(n=0;n<=5;n++)
{
k=i+j;
i=j;
j=k;
printf("%d ",k);
}
getch();
}

-Program to find the given num is Even or odd.



#include<stdio.h>
int main()
{
int n;
printf("\n Enter the number:");
scanf("%d",&n);
if(n>0)
{
n=n%2;
if(n==0)
printf("\n The given number is even");
else
printf("\n The given number is odd");
return 0;
}
}

output:
Enter the number: 222
The given number is even.

- AREA & CIRCUMFERENCE

#include<stdio.h>

int main()
{
float r, area, circum;
printf("Enter the radius of the circle:");
scanf("%f",&r);
area=3.14*r*r;
circum=2*3.14*r;
printf("\nArea=%f",area);
printf("\nCircumstance=%f",circum);
return 0;
}

Output:

Enter the radius of the circle:5
Area=78.500000
Circumstance=31.400000

-CELCIUS ---> FAHRENHEIT

#include<stdio.h>
int main()
{
float cel,faren;
printf("Enter the Celcius value...");
scanf("%f",&cel);
faren=(1.8*cel)+32;
printf("The fahrenheit value of the given value is %f",faren);
return 0;
}
 

Output:

Enter the Celcius value...8
The fahrenheit value of the given value is 46.400002

-LEAP YEAR

#include<stdio.h>
int main()
{ int year;
printf("Enter the year: ");
scanf("%d",&year);
if(year%4==0)
printf("It is a LEAP YEAR ");
else
printf("It is NOT A LEAP YEAR ");
return 0;
}

Output:

Enter the year: 2008
It is a LEAP YEAR

Enter the year: 2010
It is NOT A LEAP YEAR

 -FACTORIAL NUMBER OF GIVEN NUMBER

#include<stdio.h>
int main()
{
int fact=1,i,num;
printf("Enter the number:");
scanf("%d",&num);
for(i=1;i<=num;i++)
{
fact*=i;
}
printf("The factorial of given number is %d",fact);
return 0;
}

Output:

Enter the number:5
The factorial of given number is 120

-PALINDROME OR NOT

#include<stdio.h>
int main()
{
unsigned long int a, num, sum=0, rnum=0, rem;
printf("\nEnter the number");
scanf("%ld",&num);
a=num;
while(num!=0)
{
rem=num%10;
sum=sum+rem;
rnum=(rnum*10)+rem;
num=num/10;
}
printf("\nThe sum of the digits of %ld is %ld\n",a,sum);
printf("\nThe reverse number of the %ld is %ld",a,rnum);
if(a==rnum)
printf("\nThe given number is a palindrome");
else
printf("\nThe given number is not a palindrome");
return 0;
}

Output:
