展开全部
switch(choice){
case 1: price = 3.0; break;
case 2: price = 2.5; break;
case 3: price = 4.0; break;
case 4: price = 3.5; break;
default: price = 0.0; break;
}
应该是这样,不用加判断语句
case 1: price = 3.0; break;
case 2: price = 2.5; break;
case 3: price = 4.0; break;
case 4: price = 3.5; break;
default: price = 0.0; break;
}
应该是这样,不用加判断语句
