    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.
