was not declared in this scope

This error message typically occurs in C++ programming when a variable or function is referenced in a particular scope, but it has not been declared or defined within that scope.
For example, if a variable is declared in a function's local scope, it cannot be accessed outside of that function without being declared in a higher scope. Similarly, if a function is defined in a source file, it must be declared in a header file or the same source file before it can be called in another function.
To resolve this error, ensure that all variables and functions are properly declared and defined in the appropriate scopes. Make sure that any necessary header files are included and that any syntax errors or typos are corrected.
