 # C26496 USE_CONST_FOR_VARIABLE
 
-> The variable '*variable*' is assigned only once, mark it as `const`. See [C++ Core Guidelines con.4](https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#con4-use-const-to-define-objects-with-values-that-do-not-change-after-construction).

+## Example
+```cpp
+int GetTheNumber();
+int GiveMeTheNumber(int);
+
+void function1()
+{
+    int theNumber = GetTheNumber(); // C26496, 'theNumber' is never assigned to again, so it can be marked as const
+    std::cout << theNumber << '\n';
+    
+    GiveMeTheNumber(theNumber);
+    // ...
+}
+```
