ex5 C++請用常態分佈或student t分佈亂數產生20筆身高、體重，並計算bmi

請用常態分佈亂數產生20筆身高、體重，並計算bmi

提示：

mt19937 RV(time(0));
normal_distribution<double> X(175, 7);

double height[20];
for(int i=0; i<20; i++)
{
height[i]=X(RV);
.....

常用的機率分佈：

uniform_int_distribution

uniform_real_distribution

bernoulli_distribution

binomial_distribution

poisson_distribution

student_t_distribution
