class A{

public:
A(const char *l="Nothing");
void show()const;
};
A::A(const char*l):list(l){ //the compiler fails to initialize "list"
}
void A::show()const{
for(int i=0;i<10;i++){
cout<<list[i]<<'\t';
if(i%5==4)
cout<<endl;

cout<<endl;

int main(){
char name[10]="hello";
A a(name);
A b;
cout<<"Before assignment, b="<<endl;
b.show();
b=a;
cout<<"After assignment, b="<<endl;
b.show();
A c(a);
cout<<"After initialization, c="<<endl;
c.show();
}
The program fails to compile and throws an error message, saying that"incompatible types in assignment of 'const char*' to 'const char[10]". How can I achieve in initializing the const member list?
