What is a report generator?
What will be an ideal response?
A report generator is a tool that prepares reports to be used with a software program quickly and easily. For instance, report generators for database management systems allow reports to be created simply by declaring which data fields are to be represented as report columns and how the data should be sorted; once defined, a report can be edited as needed, and then generated on demand.

Here is a recursive function that is supposed to return the factorial. Identify the line(s) with the logical error(s). Hint: This compiles and runs, and it computes something. What is it?
``` int fact( int n ) //a { int f = 1; //b if ( 0 == n || 1 == n ) //c return f; //d else { f = fact(n - 1); //f f = (n-1) * f; //g return f; //h } } ```
