What's the actual size of the buffer of printf() function in VC2010?
As we know, printf() will print the string from the buffer in 3 situations, the buffer is full / getting user input / meet '/n' character.
However, I got a situation which didn't satisfy those 3 situations unless the buffer of printf() is less than 1 char....
In the following code, the string "H" only occupy the buffer 1 char unit, but still be printed before the for-looping.
*I'm using ANSI C in programming
#include <stdio.h>
#include <limits.h>
int main(void)
{
int n;
printf ("H");
for (n = 1; n < INT_MAX; n++)
{
}
printf ("i");
getchar();
return 0;
}
