correct me a c++ progrm!

Question

#include<iostream>

#include<stdlib.h>
using namespace std;
int func(int p,int i,int n,int val)
{
int a[10]={55,41,12,78,15,69,45,36,105};
cout<<"value of array before insertion\n";
for(i=0;i<=9;i++)
{

cout<<a[i]<<" ";
cout<<endl;
}
while(1)
{
cout<<"\n enter position to insert new value =";
cin>>p;
n=10;
if(p>n||p<0)
{
cout<<"invalid position\r";
getch();
}
else
break;
}
while(n>=p-1)
{
a[n+1]=a[n];
n--;
}
cout<<"enter new value to insert=";
cin>>val;
a[p-1]=val;
cout<<"values of array after insertion\n";
for(i=0;i<=10;i++)

cout<<a[i]<<" ";

getch();
}

int main()
{

cout<<func(p,i,n,val);
}
whats wrong with this code !its two different code which i'm merge into one code plz coorect me ! its cannot work

Answer 1

It's kind of hard to see what you're trying to do (and I'm not really cut out for debugging on a smartphone) but from what I can see:

- The two codes you are trying to merge together, one of them is to delete elements inside arrays, the other is to add elements to arrays.

- The way you placed main() in int main() is invalid. For your code to at least compile, you will have to move everything inside main() to int main().

Answer 2

Let user decide on which function to run. E.g.

int user_choice;

cout << "Please input user choice.";
cout << " 1. Add array" << endl;
cout << " 2. Delete array" << endl;
cin >> user_choice;

switch (user_choice)
{
case 1:
// codes needed to add array
break;
case 2:
// codes needed to delete array
break;
default:
// input validation
}

cout << "Press any key to continue";
getch();

Answer 3

thanks buddy I make my day

Answer 4

ok got it! but where I'm used getch means how I can manage one code over another code in only int main()! I'm confused

Answer 5

how it's work?
