will be equal to:
a) 0; b) 2; at 8; d) 10.
6. In this fragment of the program
program
mistakes
;
begin
writeln (‘
mistakes
No
’);
writeln
(‘5*5=’,25);
end
.
consider it a mistake:
a) incorrect program name;
b) the absence of a variable;
c) undefined variable name;
d) writing an arithmetic expression.
7. As a result of the program
program klass;
begin
writeln (45 / (12-3));
writeln (‘
classes
’);
end.
we will see on the screen:
a) 5 classes; at 5
classes;
b) 9 classes; d) 9
classes.
8. The values of a one-dimensional array are set using a loop:
for
i
:=1
to
5
do
A[
i
]:= 2+
i
;
As a result, the value of B will be equal to:
a) 9; b) 8; at 7; d) 6.
9. As a result of executing the program fragment
for i: = 1 to 10 do begin
if a [i]> 0 then a [i]: = a [i] / 3
else a [i]: = 2;
end;

If you have already studied several topics on the C ++ language, or simply know this programming language well, you are given the opportunity to test your knowledge by passing the test in an interactive mode! The table below shows 6 stages (parts) of testing. Test questions were specially divided into separate subgroups. This is done in order to reduce the number of questions in a separate test. As you can see, the test questions are organized in order from easy to hard, basics first, branch statements, loops, etc. For example, if you pass test 3, it is assumed that you have already passed tests 1 and 2. Of course, if you do not it's interesting to pass tests 1 and 2, you don't have to. I recommend that you start from the very beginning, with test 1. I guarantee that you will learn something new for yourself.
| C ++ testing (part 1) | Programming basics, loops (for, while, do while), multiple choice operator switch | 30 |
| C ++ testing (part 2) | Arithmetic and logical operations, selection operator if, input / output, data type casting. | 34 |
| C ++ testing (part 3) | Strings, links, pointers, arrays. | 33 |
Programming is the process of writing, testing, debugging, and maintaining software code. Program code written in some programming language from scratch or using ready-made developments. Writing applications requires a lot of knowledge, such as knowledge of the subject area, knowledge of algorithms, and of course the ability to use development tools.
To prepare young specialists for the study of specific programming languages and technologies, the Programming - Basics test was created.
Target audience of the programming test
The Fundamentals of Programming test contains very simple questions and most likely will not cause difficulties for people who have some, even minimal, programming experience.
The test is intended primarily for those who are just starting to learn programming. After consolidating theoretical knowledge, we suggest you choose one of the many ways for your further development in the field of software development.
Programming test structure
The test questions have not yet been divided into topics, as their list is being approved.
Nevertheless, the following categories of questions can already be distinguished:
- Basic concepts and terms
- Boolean algebra
- Number systems
- Simple algorithms
Further development of the test Fundamentals of programming
The most important definitions of programming terms will soon be added to the test.
To develop algorithmic thinking, the test will be supplemented with questions with pseudocode fragments.
We hope that the test will be useful to everyone who is just starting to learn programming. We are waiting for your suggestions and comments.
