OK, do you have any coding started? Hint; while loops and iterators.

this an example for a program i have made it

#include<iostream>
using namespace std;
int main()
{
int n,a,min,i=1;
cout<<"Pleas enter N";
cin>>n;
cout<<"\nPlease enter number<<i<<": ";
cin>>a;
min=a;
for(i=2;i<=n;i++)
{
cout<<"\nPlease enter number<<i<<": ";
cin>>a;
if(a<min)
min=a;
}
cout<<"\nThe min is:"<<min<<endl;
return 0;
}

The first assignment can be done the following way

const int N = 4;
int initial_value = 3;

for ( int i = 0; i < N; i++ )
{
   iota_n( std:ostream_iterator<int>( std::cout, " " ), N, initial_value++ );
   std::cout << std::endl;
}:

So all you need is to write algorithm iota_n yourself.

The second assignment can be done the following way

const int N = 4;
int initial_value = 3;

for ( int i = 0; i < N; i++ )
{
   iota_n( std:ostream_iterator<int>( std::cout, " " ), i + 1, initial_value++ );
   std::cout << std::endl;
}:

The third assignment can look as

const int N = 4;
int initial_value = 3;

for ( int i = 0; i < N; i++ )
{
   iota_n( std:ostream_iterator<int>( std::cout, " " ), N - i, initial_value++ );
   std::cout << std::endl;
}:

The forth assignment can be done as

const int N = 4;
int initial_value = 6;

for ( int i = 0; i < N; i++ )
{
   iota_n( std:ostream_iterator<int>( std::cout, " " ), i + 1, initial_value );
   std::cout << std::endl;
}:

Thx can u explain the codes please

[vlad from moscow]

It is your professor who should explain you code. As for you you shall write code yourself.

i don't have a professor i'm learning by my self
