Question about some threads

For example, if an ‘if statement’ is included in a for statement as shown below, is it difficult to achieve parallel processing using threads?
The results of one thread’s calculations are never used by another thread.

int a[100] = {0};
int b[100]; //save some value..

for(d = 0; d < 100; d++){
	a[d] = 0;
	if(b[d] != 0){
	 	for(i = 10; i < 100; i++){
			a[d] = i - 2;			
		}
	}
}

This would possibly be parallelized in a way that the for loop with i variable would be done in parallel by 32 threads.
But then a[d] stays the same and different values are written into it. So perhaps it is enough to store the last value?
