What's wrong with the code.. if I enter n value as 1 or 2, it prints some garbage value.. why it is so ?

Question

#include<stdio.h>
#include<math.h>
int main()
{
int n, i,third;
int f=0, s=1;
printf("enter the position to print the fib number: ");
scanf("%d",&n);
if(n==1)
{
printf("%d",f);
}
else if(n==2)
{
printf("%d",s);
}
else
{
for(int i=3; i<=n; i++)
{
third=f+s;
f=s;
s=third;
}
}
printf("%d",third);
return 0;
}

Answer 1

The garbage value is the value of variable *third* that you are printing at the end.

A simple fix is to move it inside the else statment
