if-else 的格式
if(boolean)
single line expression;
else if(boolean)
single line expression;
else
single line expression;
if(boolean)
{
multi lines expression;
}
else if(boolean)
{
multi lines expression;
}
else
{
multi lines expression;
}
if (age >= 30)//
if (age >= 28)//no ";" is needed
Hat_size = (weight/height)* 2.9;
Jacket_size = (height * weight) / 288;
Waist_size = weight / 5.7;
double 型的函数怎么可以直接等与 int型的那？
hat_size = (int)weifht/(int)height*2.9
剩下依次改就行了
还有 if else 要加 括号
if
{
}
else
{
}
