    <p>Okay this is similar to my last question but what I ended up doing was way too complex for something as simple as this. I simply need to get a single character or number (I will know which of these I am receiving) from the console after I press space, instead of pressing enter. I'm sure there must be a way to have the terminal read input after a space instead of a '\n'. I need to read inputs from the console in which the succeeding data types will vary depending on what the first input is, and I think reading the entire line, parsing it into strings, then parsing some of those into ints is a bit unnecessary.</p> <p>So Is this actually not possible in C++ or have I just not found it yet?</p> <p>EDIT:</p> <p>For anyone who has had this problem I'm posting my solution, because I feel like an idiot now.</p> <pre><code>#include &lt;iostream&gt; using namespace std; int main() { int command = 0, x = 0, y = 0, z = 0; char c; do { cin &gt;&gt; command; switch(command) { case 1: cin &gt;&gt; c &gt;&gt; x; cout &lt;&lt; c &lt;&lt; " " &lt;&lt; x &lt;&lt; endl; break; case 2: cin &gt;&gt; x &gt;&gt; y &gt;&gt; z; cout &lt;&lt; x &lt;&lt; " " &lt;&lt; y &lt;&lt; " " &lt;&lt; z &lt;&lt; endl; break; } } while (command); //Exits when command = 0; return 0; } </code></pre> <p>The following cin's inside the switch statement will read from the same buffer as the first cin, so there is no need to read what the command is beforehand anyway. As you can see this works fine for different types and amounts of inputs after the first cin, so there's no need to use any other solution.</p> <p>Just posting this for anyone else who may have the same problem, and not a great understanding of the way cin works.</p>

    1. CONot sure if i have understood your needs but what about std::cin >> anInt >> aChar >> aFloat ? Input of the three variables does occur on the same line, each separated by a space.

    2. COYeah that was the problem essentially, but the types of the values I had to get varied based on whatever the first input was, and I didn't realize that I could read those inputs from the same line without having to register the first character after I was done typing it. Essentially I found out that I could read different inputs from the first line that had already been typed, after I hit enter.

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.
