    <p>I've corrected the code:</p> <pre><code>//binary string input: if i enter abcd it gives its binary rep in 0's and 1's </code></pre> <p>secondly,i want to loop over the array when the binary string is being saved for instance:</p> <pre><code>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 &lt;&lt; "Please enter your msg :\n&gt;"; getline(cin, msg); //cout &lt;&lt; "You entered: " &lt;&lt; data; for(i=0;i&lt;=msg.size();i++){ for (j=0;j&lt;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&lt;8; k++,top--){ p_array[p]= m[top]; } cout &lt;&lt; array; return 0; } </code></pre> <p>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&lt;&lt; m[top] i get the binary form for abcd.</p> <p>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?</p> <p>why do i want to do this:</p> <p>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> <p>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.</p>

    1. CO'gives an error', what error, what line of code? What does 'my binary string of zeros and 1s declared under type int' mean? Are you using a string or an int, it's not clear.

    2. COThe code you have posted has multiple syntax errors, none of which have anything to do with the question you have asked. If that is your real code then fix the syntax errors first, `for (k=0, j=7; k<=7; k++, j--)` for instance and `array[k] = m[j];}`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
