Fibonacci numbers ( sequence ) is a set of numbers that start with 1 or 0 followed by a 1 proceeds on the rule that each number. 

Fibonacci number is equal to the sumof the preceding two numbers.

F(n) = 0, 1, 1, 2, 3, 5, 8, 13......

Write a program to find the fibonacci series the given number ( size of series ) by user.


int main(){
    int n;
    printf("Enter the size of series : ");
    scanf("%d", &n);
    int a=0, b=1, c;
    printf("%d %d", a, b);
    for(int i=2; i<n; i++){
        c = a + b;
        a = b;
        b = c;
        printf(" %d", c);
    return 0;

Output :

Enter the size of series : 10
0 1 1 2 3 5 8 13 21 34
