C Program to generate n fibonacci Series.

 #include<stdio.h>

main()

{

int f1=0,f2=1,f3,n,i;

clrscr();

printf("\nEnter the nth number");

scanf("%d",&n);

printf("\nFirst %d Fibonacci numbers are :",n);

if(n==1)

{

printf("\n%d",f1);

}

if(n==2)

printf("\n%d %d\t",f1,f2);

else

{

printf("%d\t%d\t",f1,f2);

i=2;

while(i<n)

{

f3=f1+f2;

printf("%d\t",f3);

f1=f2;

f2=f3;

i++;

}

}

getch();

}

Output: Enter the nth number 5 First 5 Fibonacci numbers are: 0     1       1       2       3 Enter the nth number 10 First 10 Fibonacci numbers are: 0       1       1       2       3       5     8       13      21    34
