C programming (for loops)

Code:

#include<stdio.h>
int main(){
int i=1;
for(i=0;i=-1;i=1) {
         printf("%d ",i);
if(i!=1) break;
    }
return 0;
}

The output for this is: -1. Can some explain to me why?

Code:

for(i=0;i=-1;i=1) {

= is for assignment, == is for comparison. Now, think about the anatomy of a for loop:

Code:

for (initial; loop condition; loop increment)

Every time through the loop, you have to check (execute) the loop condition to see whether you should keep looping or stop.

Thank you for your help
