Given two 3x3 arrays of integer, x1 and x2, write the code needed to copy every value from x1 to its corresponding element in x2.

#include<iostream>

#include<iomanip>

using namespacestd;

int main ()

{

int x1[3][3]={1,2,3,4,5,6,7,8,9};

int x2[3][3];

int i,j;

for(i=0;i<3;i++)

for(j=0;j<3;j++)

x2[i][j] = x1[i][j];

cout<<"copy from x1 to x2 , x2 is :";

for(i=0;i<3;i++)

for(j=0;j<3;j++)

cout<<x2[i][j]<<" ";

cout<<endl;

system("pause");

return 0;

}

/* Sample output

copy from x1 to x2 , x2 is :1 2 3 4 5 6 7 8 9

Press any key to continue . . .
