我正在为一项任务制作一组派生类。我被指示使用 char 数组(c 字符串)。当我编译时,我不断收到错误:
Homework11.cpp: In function âint main()â:
Homework11.cpp:72: error: conversion from âchar [10]â to non-scalar type âBusinessâ requested
Homework11.cpp:73: error: conversion from âchar [10]â to non-scalar type âBusinessâ requested
Homework11.cpp:74: error: conversion from âchar [10]â to non-scalar type âAccountâ requested
Homework11.cpp:75: error: conversion from âchar [10]â to non-scalar type âAccountâ requested
我相当确定我的问题源于我尝试将实例变量 Name 设置为发送的参数。这是我的代码,其中包含我认为可能存在问题的注释。
