Answer 1

#include<iostream.h>
unsigned a[20][20], i, j, n, s=0;
void main()
{
cout<<"n="; cin>>n;
for(i=1;i<=n;i++)
for(j=1;j<=n;j++)
{cout<<"a["<<i<<"]["<<j<<"]=";
cin>>a[i][j];
}
for(i=1;i<=n;i++)
for(j=1;j<=n;j++)
if(i>j)
cout<<a[i][j]<<" ";
cout<<endl;
for(i=1;i<=n;i++)
for(j=1;j<=n;j++)i
f(i<j && a[i][j]%2==0)
s=s+a[i][j];
cout<<s;
}
