+(+k--) expression in C

Question

I saw this question in a test in which we have to tell the output of the following code.

#include

int main(){
    int k = 0;
    while(+(+k--         


        

Answer 1

Here's a version of this that shows operator precedence:

+(+(k--))

The two unary + operators don't do anything, so this expression is exactly equivalent to k--. The person that wrote this most likely was trying to mess with your mind.
