I am using the most up-to-date eclipse IDE for C/C++. I have the below code. It seems simple enough. My problem is that no printf will display on the console until the main has finished (return 0). This means I get a prompt in console asking for input before I get the message telling me what to do. I fill in a number like 10 and I see 10 is now displayed in stdout followed by the first and second printf. Can anyone explain why this is? What am I doing wrong?
Code:#include <stdio.h> int main(void) { int n = 0; int i = 0; int left = 1; int right = 1; int temp = 1; printf("Enter an index: "); scanf("%d", &n); printf("Index: %d", n); if (n < 0 || n == 0) { printf("\nFibonacci index: %d\n", -1); } if (n == 1) { printf("\nFibonacci index: %d\n", 1); } for (i = 0; i < (n - 1); i++) { temp = right; right = left + temp; left = temp; } printf("\nFibonacci index: %d\n", left); return 0; }
