Printing Fibonacci Series

C Program

1.For Loop

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int x,y,n,z;
    printf("Enter Any Number:");
    scanf("%d",&n);
    x=0;
    y=1;
    for(n=n;n!=0;n--)
    {
        printf(" %d",x);
        z=y+x;
        x=y;
        y=z;
    }
}

2.While Loop

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int x,y,n,z;
    printf("Enter Any Number:");
    scanf("%d",&n);
    x=0;
    y=1;
    while(n!=0)
    {
        printf(" %d",x);
        z=y+x;
        x=y;
        y=z;
        n--;
    }
}

3.Do While Loop

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int x,y,n,z;
    printf("Enter Any Number:");
    scanf("%d",&n);
    x=0;
    y=1;
  if(n!=0)
  {
     do
      {
        printf(" %d",x);
        z=y+x;
        x=y;
        y=z;
        n--;
     }while(n!=0);

  }
}

Java Program

1.For Loop
