copied!<p>I assume that you're attempting to recreate what is allowed in more dynamic languages, such as this PHP example:</p> <pre><code>$QueryName = "GetAirports"; $$QueryName = array(/*...*/); </code></pre> <p>Where by altering the value of <code>$QueryName</code> variable you can refer to another object?</p> <p>If so, the simple answer is: you can't do that in C.</p> <p>What you can do, however, is use a single variable to <em>point to</em> multiple instances at different times.</p> <pre><code>Query *query_ptr = &myFirstQueryObject; query_ptr = &mySecondQueryObject; /* etc */ </code></pre> <p>However from your example code it appears you're simply wanting to allocate a structure? If so:</p> <pre><code>typedef struct Query { /* fields here, e.g: */ int id; int age; } Query_t; int main() { Query_t *query = malloc(sizeof(Query_t)); query->id = 1; query->age = 0; /* etc. */ return 0; } </code></pre> <p>Perhaps look up C structs and pointers.</p> <p><strong>EDIT</strong> so from further comments apparently you're wanting to create a map of <code>char*</code> <em>name</em> to <code>Query</code> object? There are several approaches for this, but the simplest is to create two arrays:</p> <pre><code>char *names[]; Query *queries[]; </code></pre> <p>As long as both arrays have the same number of elements, and the *n*th element in <code>names</code> corresponds with the *n*th in <code>queries</code>, you can iterate through <code>names</code> until you find your matching string, then use the current index to dereference the appropriate object in <code>queries</code>, or <em>vice versa</em></p>

Querying!
