C Program to generate the Fibonacci Series starting from any two numbers

#include<stdio.h>
#include<conio.h>

int main()
{
int first,second,sum,num,counter=0;
clrscr();

printf("Enter the term : ");
scanf("%d",&num);

printf("Enter First Number : ");
scanf("%d",&first);

printf("Enter Second Number : ");
scanf("%d",&second);

printf("Fibonacci Series : %d  %d  ",first,second);

while(counter< num)
    {
    sum=first+second;
    printf("%d  ",sum);
    first=second;
    second=sum;
    counter++;
    }
getch();
}

Output :

Enter the term : 5
Enter First Number : 1

Enter Second Number : 3

Fibonacci Series : 1 3 4 7 11 18 29
