How do you make a program recognize a letter or a combination of letters (e.g. asdaasdf) in a string which I input in the program (or from a file)?
(C++ or Basic)

If you want to check that the string contains ONLY letters, you could use isalpha (#include <cctype>) and a loop.
To search for a particular string, the std::string has plenty of search routines, depends on how you want to go about it.
A quick google search gave me this.

Does that answer your question?

i would guess that he hasn't included error-checking in his idea. also from the question, "2" is a valid string input. yes, refer to the standard library for string manipulation functions. i get the idea that he wants to search for a particular word in an app.

there are numerous ways to do this.

good luck!

Let me toss out some asides, here. Any "letter" is just a binary pattern. If you know it to be some particular coding scheme, then you can write in view of that scheme. Good implementations will attempt to adjust somewhat to the locale. The type of functions that L7 is referring to (isalpha, isnumeric, etc.) will give you more chance of success in terms of portability than mere comparison to a code table. When it comes to comparing one code against another, directly, then locale doesn't really matter except insofar as it might determine the size of a "letter". The things available to you will vary, depending upon language. You mention C++/Basic, but that's rather presumptuous. You should probably narrow it down and put it in the appropriate forum.

what he meant is to pick your language as they each have separate libraries for this. you kind of selected an interval that's pretty broad. btw, all the pseudocode he gave you differs on language. just pick c++.
