ERROR: expected primary-expression

[quayda]

I'm getting

expected primary-expression before '=' token

for lines 40 and 43, sum and sumHits. I don't know what I'm doing wrong :/. Why am I not getting the same error for average?? Thanks!!

#include <iostream>
#include <stdio.h>
using namespace std;

#define H = 1
#define h = 1
#define O = 1
#define o = 1
#define W = 0
#define w = 0
#define S = 0
#define s = 0
#define P = 0
#define p = 0

int main ()
{
    int player;                 //Assign player number
    double sum;                 //Assign variable for sum of H, h and O, o
    double sumHits;             //Assign variable for sum of only H and h
    double average;             //Assign variable for average of H and O
    char size[100];             //Allows compiler to view user input as array
    int b;                      //Assign variable for integer size

         while (size[b] != 0)
         if (( size[b] = 'h','o','w','s','p') || (size[b] = 'H','O','W','S','P'))
         { letters++; b++; }}

    sum = H + h + O + o;
    
    //Summate 
    sumHits = H + h;
    
    //Calculate batting average
    average = sumHits/sum;

This is how you define something:

#define number 1

not:

#define number = 1
