Fibonacci series code

#include<stdio.h>

int main() {

int n;

printf("Enter the number of terms: ");

scanf("%d", &n);

int a = 0;

int b = 1;

if (n == 1) {

printf("%dn", a);

return 0;

}

if (n == 2) {

printf("%d, %dn", a, b);

return 0;

}

printf("%d, %d", a, b);

for (int i = 3; i <= n; i++) {

int sum = a + b;

printf(", %d", sum);

a = b;

b = sum;

}

printf("n");

return 0;

}

Output :

Enter the number of terms: 4

0, 1, 1, 2
