Write a program to generate Fibonacci number using do while loop.

#include<stdio.h>
#include<conio.h>
void main()
{
int n1=0,n2=1,n3,n,i=0;
printf("enter the value of n:");
scanf("%d",&n);
    do
    {
    n3=n1+n2;
    n1=n2;
    n2=n3;
    i++;
}
while(i<n-2);
printf("the fibonacci number is %d",n3);
}
