hi frd,

just see if u can find this appropriate….

#include <iostream><br />
using namespace std;<br />
<br />
main(){<br />
<br />
int a[10];<br />
int n,i,j=0,k;<br />
<br />
cout<<"Enter the value for n: ";<br />
cin>>n;<br />
k=n;<br />
<br />
for (i=0 ;i < 10; i++)<br />
a=i + 1;<br />
<br />
while(k>0){<br />
        for(i=(0+j);i<n;i++)<br />
                 cout<<a<<" ";<br />
        for(i=n-2;i>=(0+j);i--)<br />
                 cout<<a<<" ";<br />
        cout<<endl;<br />
        j++;<br />
        for(i=0;i<j;i++)<br />
                 cout<<"  ";<br />
        k--;<br />
}<br />
<br />
return 0;<br />
}<br />
<br />
Output :<br />
<br />
Enter the value for n: 5<br />
1 2 3 4 5 4 3 2 1<br />
2 3 4 5 4 3 2<br />
    3 4 5 4 3<br />
      4 5 4<br />
        5  </iostream>

#include <iostream>

using namespace std;

main(){

int a[10];

int n,i,j=0,k;

cout<<"Enter the value for n: ";

cin>>n;

k=n;

for (i=0 ;i < 10; i++)

a=i + 1;

while(k>0){

for(i=(0+j);i<n;i++)

cout<<a<<" ";

for(i=n-2;i>=(0+j);i--)

cout<<a<<" ";

cout<<endl;

j++;

for(i=0;i<j;i++)

cout<<" ";

k--;

}

return 0;

}

Output :

Enter the value for n: 5

1 2 3 4 5 4 3 2 1

2 3 4 5 4 3 2

3 4 5 4 3

4 5 4

5 </iostream>
