Visualization of Code Structure

This document visualizes the relations within the provided C++ code snippet using DOT notation to represent the structure and flow of the program.

Code Overview

C++ Code Snippet

#include 
using namespace std;

int main() {
    int min, now;
    cin >> now;
    min = now;
    while (now != 0) {
        if (now < min) {
            min = now;
        }
        cin >> now;
    }
    cout << min;
    return 0;
}

Explanation of the Code

• The program reads a series of integers from the standard input.
• It determines the minimum value from the input until a zero is encountered.
• The minimum value is then printed to the standard output.

DOT Notation Representation

Below is the DOT representation that visualizes the structure and flow of the given C++ code.

digraph CppCode {
    node [shape=box];

    Start [label="Start\n(main function)"];
    Input [label="Input: now"];
    Initialize [label="min = now"];
    ConditionWhile [label="while (now != 0)"];
    ConditionIf [label="if (now < min)"];
    UpdateMin [label="min = now"];
    InputAgain [label="Input: now"];
    Output [label="Output: min"];
    End [label="End"];

    Start -> Input;
    Input -> Initialize;
    Initialize -> ConditionWhile;
    ConditionWhile -> ConditionIf;
    ConditionIf -> UpdateMin [label="true"];
    ConditionIf -> InputAgain [label="false"];
    UpdateMin -> InputAgain;
    InputAgain -> ConditionWhile;
    ConditionWhile -> Output [label="false"];
    Output -> End;
}

Key Components

1. Start and End:

   • Indicates the beginning and termination points of the program.

2. Input and Output:

   • Represents input and output operations for reading from standard input and writing to standard output.

3. Conditions:

   • Displays the logical conditions that control the flow of the program, such as the while loop and the if statement.

4. Variables:

   • The variables min and now are pivotal in determining the minimum value.
