第一块

const int size = 500000000;
int sum =0;
int *num1 = new int[size];//initialized between 1-250
int *num2 = new int[size];//initialized between 1-250
for (int i = 0; i < size; i++)
{
    sum +=(num1[i] / num2[i]);
}

第二块

const int size = 500000000;
int sum =0;
float *num1 = new float [size]; //initialized between 1-250 
float *num2 = new float [size]; //initialized between 1-250
for (int i = 0; i < size; i++)
{
