String 是一个字符序列,可以包含零个或多个字符,而 char 是一个单一的字符。当你尝试将一个包含多个字符的字符串赋值给一个只能存储单个字符的变量时,编译器会抛出一个类型不匹配的错误,提示“string cannot be converted to char”。 2. 给出可能导致这个错误的常见场景 直接赋值:尝试将一个字符串直接赋值给一...

方法一：将char name[10];改成string name;方法二：将string变量转换成char[]变量；具体的实例如下：这个由于我们知道string的长度，可以根据length()函数得到，又可以根据下标直接访问，所以用一个循环就可以赋值了。这样的转换不可直接赋值。string pp = "dagah";char p[8];int i;for( i=0;i<...
