-> warning C6200: index \<name> is out of valid index range \<min> to \<max> for non-stack buffer \<variable>
+> Index '*index*' is out of valid index range '*min*' to '*max*' for non-stack buffer '*parameter-name*'
 
-This warning indicates that an integer offset into the specified array exceeds the maximum bounds of that array. This defect might cause random behavior or crashes.
+This warning indicates that an integer offset into the specified non-stack array exceeds the maximum bounds of that array, potentially causing random behavior and/or crashes.
+
+## Remarks
 
 One common cause of this defect is using the size of an array as an index into the array. Because C/C++ array indexing is zero-based, the maximum legal index into an array is one less than the number of array elements.
 
+Code analysis name: INDEX_EXCEEDS_MAX_NONSTACK
+
 ## Example
 
-The following code generates this warning because the **`for`** loop exceeds the index range:
+The following code generates this warning. This issue stems from the **`for`** loop exceeding the index range, attempting to access index 14 (the 15th element) when index 13 (the 14th element) is the last:
 
 ```cpp
-int buff[14]; // array of 0..13 elements
 void f()
 {
-   for (int i=0; i<=14;i++) // i exceeds the index
-   {
-     buff[i]= 0; // warning C6200
-     // code...
-   }
+    int* buff = new int[14]; // array of 0..13 elements
+    for (int i = 0; i <= 14; i++) // i exceeds the index
+    {
+        buff[i] = 0; // warning C6200
+    }
+    delete[] buff;
 }
 ```
 
 To correct both warnings, use correct array size as shown in the following code:
 
 ```cpp
-int buff[14]; // array of 0..13 elements
 void f()
 {
-   for ( int i=0; i < 14; i++) // loop stops when i < 14
-   {
-     buff[i]= 0; // initialize buffer
-    // code...
-   }
+    int* buff = new int[14]; // array of 0..13 elements
+    for (int i = 0; i < 14; i++) // i == 13 on the final iteration
+    {
+        buff[i] = 0; // initialize buffer
+    }
+    delete[] buff;
 }
 ```
