 # nextstep-coordinate

 nextstep 좌표계산기를 OOP와 TDD를 이용하여 구현해보자.
+
+# 1️⃣ 좌표계산기(선 길이)
+
+## 기능 요구사항
+- 사용자가 점에 대한 좌표 정보를 입력하는 메뉴를 구성한다.
+- 좌표 정보는 괄호"(", ")"로 둘러쌓여 있으며 쉼표(,)로 x값과 y값을 구분한다.
+- X, Y좌표 모두 최대 24까지만 입력할 수 있다.
+- 입력 범위를 초과할 경우 에러 문구를 출력하고 다시 입력을 받는다.
+- 정상적인 좌표값을 입력한 경우, 해당 좌표에 특수문자를 표시한다.
+- 좌표값을 두 개 입력한 경우, 두 점을 있는 직선으로 가정한다. 좌표값과 좌표값 사이는 '-' 문자로 구분한다.
+- 직선인 경우는 두 점 사이 거리를 계산해서 출력한다.
+
+### 실행 결과
+```
+좌표를 입력하세요.
+(10,10)-(14,15)
+```
+```
+두 점 사이 거리는 6.403124
+```
+
+# 2️⃣ 좌표계산기(사각형 면적)
+
+## 기능 요구사항
+- 좌표값을 두 개 입력한 경우, 두 점을 있는 직선으로 가정한다. 좌표값과 좌표값 사이는 '-' 문자로 구분한다.
+- 좌표값을 네 개 입력한 경우, 네 점을 연결하는 사각형으로 가정한다.
+  - 네 점이 뒤틀어진 사다리꼴이나 마름모는 제외하고 직사각형만 허용하도록 검사한다.
+  - 사각형인 경우 사각형의 넓이를 계산해서 출력한다.
+  
+### 실행 결과
+```
+좌표를 입력하세요.
+(10,10)-(22,10)-(22,18)-(10,18)
+```
+
+```
+사각형 넓이는 96
+```
+
+# 3️⃣ 좌표계산(삼각형 면적)
+
+## 기능 요구사항
+- 좌표값을 두 개 입력한 경우, 두 점을 있는 직선으로 가정한다. 좌표값과 좌표값 사이는 '-' 문자로 구분한다.
+- 좌표값을 세 개 입력한 경우, 세 점을 연결하는 삼각형으로 가정한다.
+  - 삼각형인 경우 삼각형의 넓이를 계산해서 출력한다.
+
+### 실행 결과
+```
+좌표를 입력하세요.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
