finding the fibonacci series between the ranges each and every series 5-8 like this in c language

 #include<conio.h>

#include<stdio.h>

int main()

{

     int r1=5,r2=7,a,b,c;

     for(int  i= r1; i<=r2; i++){

         printf("The fibonacci series of %d :: ",i);

         a=0,b=1; 

         printf("%d %d",a,b);

        for(int j=2; j<i; j++){

            c=a+b;

            printf(" %d",c);

            a=b;

            b=c;

        }

        printf("\n");

        

     }

     return 0;
