C++/A question on "Field lenght"

Advertisement


Question
Hi Bill,

I don't know if this is directly related to your field of expertise... I'm translating into Spanish a software to manage surveys, and I have a problem with the following sentence:

For dropdown fields, the "Field Lenght" is the maximum number of digits that any option can use (e.g. 88 for a "Refused" option requires 2 digits).

A bit of context: by using the software, the user can create different questions, including dropdown lists. In the text, it is explained how to set the "Field Lenght". However, I don't understand the sentence! Could you help me!

Best,

Patricia


Answer
Hi Patricia!

I think it means "Field length is the maximum number of digits allowed for the field".  If the user can enter a number from 10 to 999, then "Field Length" would be 3.  The software would presumably prevent the user from entering 1020 if the field length were 3.

Take care,
Bill

Expertise

I can answer questions about C++, programming algorithms, Windows programming in MFC (which is C++). I cannot answer questions about STL (templates) and I have no experience with Linux. I do enjoy reviewing code and critiquing it or finding problems in it. I will also gladly show better algorithms or methods if you want to take advantage of that.

Experience

I've developed a commercial embedded C compiler/assembler and IDE with debugger toolset, of which the IDE and debugger are written in C++. I work in the industry writing high tech embedded programs and Windows programs to communicate with the embedded devices.
