Question

Program a2; var a,b,c,min:real; begin writeln('Введите три числа'); readln(a,b,c); min:=a; if b if c writeln('min=',min) end.КАК РЕШАТЬ??????????????? А)а=10,b=5 и с =1 Б)а=10,b=5 и с =7 В)а=2,b=10,с=5

Answer 1

A: min =1;
Б: min =5
В: min =2
var a,b,c,min:real;
begin
writeln('Введите три числа');
readln(a,b,c);
min:=a;
if b<min then min:=b;
if c<min then min:=c;
writeln('min= ' ,min);
end.

Answer 2

Program Explanation

The given program is written in Pascal and aims to find the minimum value among three numbers (a, b, and c) and print it. Let's break down the program step by step.

program a2;
var a, b, c, min: real;
begin
  writeln('Введите три числа');
  readln(a, b, c);
  min := a;
  if b < min then
    min := b;
  if c < min then
    min := c;
  writeln('min=', min);
end.

Step-by-Step Explanation

1. The program starts with the declaration of variables `a`, `b`, `c`, and `min`, all of which are of the `real` data type.

2. The program prompts the user to enter three numbers by displaying the message "Введите три числа" (which translates to "Enter three numbers" in English).

3. The `readln` function is used to read the input values of `a`, `b`, and `c` from the user.

4. The variable `min` is initialized with the value of `a`.

5. The program checks if `b` is less than `min`. If it is, then the value of `min` is updated to `b`.

6. The program checks if `c` is less than `min`. If it is, then the value of `min` is updated to `c`.

7. Finally, the program displays the minimum value by printing the message "min=" followed by the value of `min`.

Solving the Given Examples

Let's solve the given examples using the provided program:

Example A: - a = 10, b = 5, c = 1 - Plugging in these values into the program: - `a := 10` - `b := 5` - `c := 1` - The program will output: - `min = 1` - Therefore, the correct answer for Example A is 1.

Example B: - a = 10, b = 5, c = 7 - Plugging in these values into the program: - `a := 10` - `b := 5` - `c := 7` - The program will output: - `min = 5` - Therefore, the correct answer for Example B is 5.

Example C: - a = 2, b = 10, c = 5 - Plugging in these values into the program: - `a := 2` - `b := 10` - `c := 5` - The program will output: - `min = 2` - Therefore, the correct answer for Example C is 2.
