How do I use a increment operator in parallel in OpenMP

Question

I want to increment count variable in all of my threads if a condition is met. Is there a better way to do this other than enclosing the count variable in a critical block or using count[] as an array?

pragma omp parallel for num_threads(number_of_threads)

int id = omp_get_thread_num();    
for(i=1; i < ht; i++) { 
    for(j=1; j < wd; j++) {
                            
            // Some random code
                            
            double mag = sqrt(a[i] * a[i] + b[j] * b[j]); 
                
            if(mag > 100) {         
                  #pragma omp critical 
                  { 
                        count++;
                  }
            } else {
                  // do nothing
            }
        }
    }
}
