    <p>Im working on my homework assignment and I stuck because in the assignment we have to ask the user to enter a file name but also to type in either wc cc or lc (word count, character count, and line count of a file. For example, wc filename.txt. Im suppose to check the file to see if its valid or not which i understand and I know how to compare the users input to determine the different kind of function to run, but I dont understand how you could do it together. Any ideas? This is what I have so far.</p> <pre><code>#include &lt;iostream&gt; #include &lt;string&gt; #include &lt;fstream&gt; using namespace std; int main() { string line; string file; ifstream input; //input file stream int i; cout &lt;&lt; "Enter a file name" &lt;&lt; endl; while(true){ cout &lt;&lt; "&gt;" ; getline(cin,file); input.open(file.c_str()); if (input.fail()) { cerr &lt;&lt; "ERROR: Failed to open file " &lt;&lt; file &lt;&lt; endl; input.clear(); } else { i = 0; while (getline(input, line)) if(line == "wc"){ cout &lt;&lt; "The word count is: " &lt;&lt; endl; } else if(line == "cc"){ cout &lt;&lt; "The character count is: " &lt;&lt; endl; } else if(line == "lc"){ cout &lt;&lt; "The line count is: " &lt;&lt; endl; } else if(line == "exit"){ return 0; } else{ cout &lt;&lt; "----NOTE----" &lt;&lt; endl; cout &lt;&lt; "Available Commands: " &lt;&lt; endl; cout &lt;&lt;"lc \"filename\"" &lt;&lt; endl; cout &lt;&lt;"cc \"filename\"" &lt;&lt; endl; cout &lt;&lt;"wc \"filename\"" &lt;&lt; endl; cout &lt;&lt;"exit" &lt;&lt; endl; } } } return 0; } void wordCount(){ //TBD } void characterCount(){ //TBD } void lineCount(){ //TBD } </code></pre>

    1. COIm not sure from your question what is the problem, what do you mean when you say together. you obviously first need to check the file and if nothing is wrong preform the action.

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.
