    copied!<pre><code>for(int j=i; j&lt;= i ;j++) </code></pre> <p>This code makes zero sense you don't need a loop here. The reason is it will only ever have once case.</p> <p><code>i = j</code> you're setting <code>j</code> to <code>i</code> there for <code>j</code> can never been less then <code>i</code>.</p> <pre><code>for(int i=0; i &lt; num; i++) { cout &lt;&lt; "Enter the name for score # " &lt;&lt; i+1 &lt;&lt; " :"; cin &gt;&gt; name; t[i] = name; cout &lt;&lt; "Enter the score for score # " &lt;&lt; i+1 &lt;&lt; " :"; cin &gt;&gt; score; m[i] = score; } </code></pre> <p>this is the same thing you wrote essentially. </p> <p>EDIT UPDATE:</p> <p>Well to answer what the OP was actually asking.... I suppose. </p> <p>It's simply because you aren't including <code>&lt;string&gt;</code> </p> <p>here is the entire project with a couple of optimizations and error checks. </p> <pre><code>#include &lt;iostream&gt; #include &lt;string&gt; using namespace std; int main() { const int num = 5; string t[num], test; int m[num]; bool integer = false; for(int i=0; i &lt; num; i++) { cout &lt;&lt; "Enter the name for score # " &lt;&lt; i+1 &lt;&lt; " :"; cin &gt;&gt; t[i]; cin.clear(); cin.ignore(std::numeric_limits&lt;std::streamsize&gt;::max(), '\n'); integer = false; while(integer == false){ cout &lt;&lt; "Enter the score for score # " &lt;&lt; i+1 &lt;&lt; " :"; cin &gt;&gt; m[i]; if(!std::cin.fail()) integer = true; cin.clear(); cin.ignore(std::numeric_limits&lt;std::streamsize&gt;::max(), '\n'); } } for(int i=0; i &lt; num; i++) cout &lt;&lt; m[i] &lt;&lt; endl; } </code></pre> <p>I felt the need for the name and score variables were pointless you can just directly store them into your array. <strong>Also, I would make sure you do some error checking to see when you are <code>cin</code> ints they are actually ints not a string.</strong> Hope this helps. </p>
