Firstly, do you know what is recursion?
void a(int z){
if(z>0){
a(z-1);
cout<<z;
}
}This is a type of recursion. Calling a(5) will output:
12345
Calling stack:
a(5){a(4){a(3){a(2){a(1){a(0){};
cout<<1;};
cout<<2;};
cout<<3;};
cout<<4;};
cout<<5;}
Any idea on it now? We are not supposed to help you write the whole code, but to teach.
