C++ 为什么我所有的布尔人都是真的？

我通过打印这些值来测试我的代码，看看为什么它没有输出我应该得到的值。我发现我所有的用于弦乐的布尔人都被认为是真的，我似乎不知道为什么。我试着在网上搜索，但什么也找不到。我对代码的理解不够深刻，无法理解这里出了什么问题

cout我认为这是因为您没有初始化布尔变量。没有一行设置为“false”。因此，它们得到随机值，即任何非零值都被视为“true”

设置布尔值的默认值
bool-fer=false、bump=false、zip=false、pir=false、test=false；


如果

错误，则使用的是

if（zip=true）//如果zip=true

if（zip==true）//如果zip=true
？


如果需要，请使用else

//骑
如果（乘坐=“摩天轮”）{
rp=rp+75.00；
fer=真；
}

否则，如果（行驶=“碰碰车”）{
rp=rp+50.00；
凹凸=真；
}


骑乘不能与“摩天轮”和“碰碰车”相提并论同时。
请在问题中包括输入输出和预期输出您正在访问未初始化的值
rp=rp+75.00；
，导致未定义的行为您也不初始化其他变量，并且
fer=true
赋值不比较请注意编译器警告。如果设置正确，您的代码将被删除oes未编译：谢谢！！我已经解决了问题！！这是一个问题，但不是问题所在。
if（zip=true）
中的条件计算为
true
是否初始化了
zip
