![c – 错误：从’const char *’到’char’的无效转换[-fpermissive]](/img/no_img.png "c – 错误：从’const char *’到’char’的无效转换[-fpermissive]")
参见英文答案 > invalid conversion from ‘const char*’ to ‘char’ 2个
#include<stdio.h>
#include<iostream>
#include<fstream>
#include<string.h>
using namespace std;
class base {
public:
int lookup(char c);
}; // class base
int base::lookup(char c)
{
cout << c << endl;
} // base::lookup
int main() {
base b;
char c = "i";
b.lookup(c);
} // main
在编译上面的代码我得到以下错误：
g++ -c test.cpp test.cpp: In function ‘int main()’: test.cpp:20:10:
error: invalid conversion from ‘const char*’ to ‘char’ [-fpermissive]
最佳答案
尝试更换
char c = "i";
同
char c = 'i';
