How to use the function like this:
void entry (int i)?
Here is the source code:
#include<iostream>
using namespace std;
int main()
{
int i=0;
int phone_book[3]={ 1, 2, 3 };
void entry (int i) // simple use
{
cout<<phone_book<<" "<<"n";
}
}
I want to use the function : void entry (int i),
and let the program output the first value of the array phone_book,
but it falled.
How to use this kind of function, and what is wrong in my program?
Thank you, and sorry for my poor English. | 2. Re: How to use this kind of function? #2562 Posted by: 2003-08-26 14:09:52 | Edit:
cout<<phone_book<<" "<<"n"; should be:
cout<<phone_book<<" "<<"n";
still falled.
It seems that if I have already send out the post, I can't modify if. | 3. Re: How to use this kind of function? #2563 Posted by: 2003-08-26 14:15:11 |
#include<iostream>
#include<istream>
using namespace std;
int main()
{
int i=0;
int phone_book[3]={ 1, 2, 3 };
void entry (int i) {
cout<<phone_book[ i ]<<" "<<"n";
}
}
[code]
cout<<phone_book<<" "<<"n"; should be:
cout<<phone_book[ i ]<<" "<<"n";
Sorry, when I type the source code, all seem fine, but after I clcik the post button,
some symbols always are missed.

#include<iostream>
#include<istream>
/*
*first, a function can not be defined within another function.
*second, all the funciton except int main() must be called within the function int main().
*/
using namespace std;
void entry(int i); //the form of the function
int main()
{
int i;
cout<<"there are three recorders, please entry the value of the recorder number, 0, 1, or 2?n";
cin>>i;
entry(i); //call the function entry (int i) within the function main()
}
void entry(int i) //define a function
{
int phone_book[3]={ 3, 6, 9 };
cout<<"the recorder"<<i<<"is"<<phone_book<<"n";
}
Hope this make sense.
