[whocares21]

hey. i have a function in a struct and i want to call it from main function

Here is the a part of my code:

struct X{

int search(char *);
};

and in the main func:

X test;
char ch='a';
test.search(ch);//ERROR LINE 

and here is the error msg: error: invalid conversion from 'char' to 'char*'|

Change char ch='a'; to char* ch = "a";
