Please help to find mistake

Question

#include <stdio.h>
int fibonacci (int i)
int main() {
int i;
for (i=1;i<=10;i++)
{
printf ("%d\t\n",fibonacci(i));
}
}
int fibonacci (int i)
{
if(i==0)
}
if(i==1)
{
return 1;
}
return fibonacci (i_1)+fibonacci (i_2);
}

Man, Fibonacci implementation in C is a basic one, along with factorial. But you did some big mistakes.

#include <stdio.h>

int fibonacci(int fib); //semicolon is required on a prototype function

int main() {

int i = 0; //always initialize your variables
//you can read a variable from stdin (keyboard) to calculate Fibonacci until that number
int n = 0, m = 0;
scanf("%d", &n);
printf("Fibonacci series until the number: %d\n\n", n);

//replace 10 with n
for (i=1;i<=n;i++) {
printf ("%d\n",fibonacci(m));
m++;
}
return 0;
}

int fibonacci(int fib) {
if(fib==0 || fib==1) {
return fib;
}
else {
return fibonacci(fib-1) + fibonacci(fib-2);
}
}

LE: I commented and explained the above solution. It is recommended for beginners in C programming language.
