What am I doing wrong with this for loop in C?-CodePudding

I'm trying to implement the below code in a for loop, to avoid needing to have every XOR term written out separately.

unsigned int check_0 = P0^en[2]^en[4]^en[6]^en[8]^en[10]^en[12]^en[14]^en[16]^en[18]^en[20]^en[22]^en[24]^en[26]^en[28]^en[30];

This is what I've written, but it doesn't work. Can someone please let me know what I'm doing wrong?

unsigned int check_0z = P0;
unsigned int check_0 = 0;

 int i = 2;
  for (i = 2; i > 30; i  = 2){
    check_0 = check_0z^en[i];
    check_0z = check_0;
  }

CodePudding user response：

I can use while or do... while instead of for loop. That is suitable.

first of all P0 and en are not declared. Please elaborate what you are trying to do. Also in for loop there should be i<=30.
