Consider:
#include "stdio.h"
int main()
{
int a=3, b=4, c=5;
printf("%d %d %d\n", (a, b, c));
}
And the result is:
5 2280760 2281472
What is the explanation?
You have caused an undefined behavior:
This –
(a,b,c)is evaluated as the last parameter, e.g.c, so the first printed number is 5 (c = 5) the other two are uninitialized parameters.
