C Program to Display Fibonacci Sequence

Write a program of Fibonacci Series

#include <stdio.h>
	
void fiber(int n)
 {
     static int previous=1,preprevious=0,current=0;
     printf("%d ",preprevious);
     if(n>1)
     {
         current = previous + preprevious;
         preprevious=previous;
         previous=current;
         fiber(n-1);
     }
    
 }

void  main()
 {
     printf("Fibonacci: ");
    fiber(5);
 } 

Output :

Fibonacci: 0 1 1 2 3  

Write a program of Pointer

#include <stdio.h>


int pointer(int * a)
{
    int p=8;
    printf("What is the value of adsress pointer %d value  of a before ++a  : %d\n",a,*a);
    
    *++a=p;
    
    return *a;
}

int main()
{
    
    int  p=100;
    printf("After the value  of increment ++p %d\n",pointer(&p));

    return 0;
}

Output :

What is the value of adress pointer  82182492 value  of a before ++a  : 100                                                                                            
after the value  of ++p 8
