Answer / alice
You can't. You have to construct a table of two-field
structures, where the first field is the function name as a
string, and the second field is just the function name
(which the compiler will convert to its calling address).
Then search the table to get a string match in the first
field, and use the second field to call the function.

Answer / hemant ware
A function can be called by object name and a function
name (sring ) with dot(.) operator.
e.g
class hi
{
void string()
{
cout<<"hello I am in string function";
}
};
void main()
{
hi h1;
h1.string();
}
