Answer 1

#include <iostream>

#include <math.h>

using namespace std;

int main()

{int a[50][50],n,i,m,j;

cout<<"n=";cin>>n;

cout<<"m=";cin>>m;

for(i=1;i<=n;i++)

for(j=1;j<=m;j++)

{

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

cin>>a[i][j];

}

for(i=1;i<=n;i++)

{for(j=1;j<=m;j++)

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

cout<<endl;

}

cout<<endl;

cout<<endl;

for(i=1;i<=n;i++)

for(j=1;j<=m;j++)

if(a[i][j]%2==0)

a[i][j]=pow(a[i][j],3);

for(i=1;i<=n;i++)

{for(j=1;j<=m;j++)

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

cout<<endl;

}

}

Succes!
