}
double get_jecketsize(double height,double weight,int age)
{if(age <= 30)return 1.0*(height * weight)/288;//elsereturn 1.0*(height * weight)/288 + ((age - 30)%10)*(1.0/8);
}

{if(age <= 28)return weight / 5.7;//elsereturn weight / 5.7 + ((age - 28)%2)*(1.0/10);
}

结果：

Enter the height,the weight and the age :
69 185 50
The size of cap is 7.78
The size of jecket is 44.32
The size of waist is 32.46
