Program to access Element in Array

 #include <iostream>

#define m 100

using namespace std;


int main()

{

    int arr[m][m],r,c,i,j;

    cout<<"Enter Your Number of Row and Column: ";

    cin>>r>>c;

    for(i=0;i<r;i++){

          for(j=0;j<c;j++){

                cout<<"Enter "<<i<<" Row "<<j<<" Column :";

                cin>>arr[i][j];

          }

    }

    for(i=0;i<r;i++){

    for(j=0;j<c;j++){

          cout<<arr[i][j]<<" ";

      }

    cout<<endl;

    }

    cout<<"Enter Your Row and Column and you want to access: ";

    cin>>r>>c;

    cout<<"Your Element is "<<arr[r][c];

    return 0;

}


Check Palindrome Using c++

 #include <iostream>


using namespace std;


int main()

{

    int n,num=0,r;

    cin>>n;

    int a = n;

    while(n>0){

         r = n%10;

         num = num*10 + r;

         n/=10;

    }

//     cout<<num;

    if(num==a)

    cout<<"Palindrome";

    else

    cout<<"Not Palindrome";

    cout<<endl;


    return 0;

}
