binary output in C++ and saving binary string in array

I've corrected the code:

//binary string input: if i enter abcd it gives its binary rep in 0's and 1's

secondly,i want to loop over the array when the binary string is being saved for instance:

int main() {

string msg;
int i;
int j;
int k;
int m[8];
int array[100];
int s;
int p_array[100];


// Taking a string as input from user............................................input

cout << "Please enter your msg :\n>";
getline(cin, msg);
//cout << "You entered: " << data;
for(i=0;i<=msg.size();i++){
for (j=0;j<8;j++){
    m[j]= msg[i] % 2;  //remainder gives us binary value
        msg[i] = msg[i]/2;
}
int top, k,p;
for(k=0,top =7; k<8; k++,top--){
p_array[p]= m[top];

}

cout << array;
return 0;
}

problem1: The output gives me this value for abcd = 0x22fbd0. why? i want the value in binary. if i dont use the array and only take cout<< m[top] i get the binary form for abcd.

problem 2: i want to fill the p_array this way: the next 8 bits after array is filled from top = 7 to 0, to start filling in from position 8 in array, and then the next 8 bits after that from position 15 and so on. how should i make that possible?

why do i want to do this:

because after this is done, then from the entire p_array i need to pick 16 bits at a time and save it to a new array this way:

p_array (first 16 bits) + new array (0 initially) = newarray next 16 bits from p_array + new array = newarray .....and so on till i get the final sum in new array.
