Accepted answer
The reason why your teacher didn't bother to initialize i to zero when it was declared is because this is the default value for a global int variable (i.e. a variable declared outside all functions) in any case.

In general, default values correspond to all bits being zero which, in the case of an int, represents a value of zero.

that really works, but I am wondering why my teacher wrote it like that: int i;
with no Zero

Also why we use zero anyway.

Regards.

The problem lies with this line:

for (i=10; i>=1; i --)}

The curly brace at the end is the wrong way around. It should be:

for (i=10; i>=1; i --){

int i=0;
int main ()
{
for (i=10; i>=1; i --)
{
printf("%d ",i);
}
}
