Algorithmic constructions
Do you want to learn how to create powerful, "intelligent", versatile and useful programs?
Then you need to learn the three main forms of program execution control. According to the theory of computer systems, a good programming language should provide the implementation of three forms of control over the process of program execution:

1. Sequence:  execution of sequential statements - we have already met with this in earlier courses. All our previous programs were some sequence of statements.

2. Selection: 
if such and such a case,
    then do it
otherwise do that

3. Repeat: 
while (condition is true)
     do it).


The second form,  choosing between different courses of action, greatly increases the efficiency of computers.

A simple example. 
It is necessary to enter two real numbers from the keyboard and determine the largest of them.

Problem

According to the condition of the problem, we need to display one of two answer options: if the first number is greater than the second, then display it on the screen, if there is no — then the second number
 
Let's consider the first solution to this problem: the result is immediately displayed on the screen.
1. Run the program for execution.
2. Analyze the input and output data.
