Define the term dementia Rating:
Dementia is a term used to describe a decline in cognitive function that is severe enough to interfere with a person's daily life and activities. This decline can affect a person's memory, language, problem-solving, and judgment skills. Dementia is not a specific disease, but rather a term that describes a group of symptoms that may occur as a result of a variety of underlying conditions.
One of the most common causes of dementia is Alzheimer's disease, which is a progressive and degenerative disorder that attacks the brain's nerve cells, leading to the death of brain cells and a loss of function. Other causes of dementia include strokes, brain injuries, Parkinson's disease, and HIV/AIDS.
Symptoms of dementia can vary widely, depending on the underlying cause and the part of the brain that is affected. Early symptoms may include memory loss, difficulty with language, disorientation, mood changes, and difficulty with problem-solving and decision-making. As the condition progresses, symptoms may become more severe and may include significant memory loss, inability to communicate, difficulty with basic tasks such as bathing and dressing, and changes in behavior and personality.
Dementia is a serious condition that can have a significant impact on a person's quality of life and the lives of their family and caregivers. There is currently no cure for dementia, but there are treatments and strategies that can help to manage the symptoms and improve quality of life. These may include medications, therapy, and support from caregivers. It is important for individuals with dementia and their caregivers to work closely with a healthcare team to develop a plan of care that meets the individual's needs.
#define directive (C/C++)
The identifier remains defined and can be tested by using the if defined and ifdef directives. The actual arguments that follows an instance of identifier in the source file are matched to the corresponding formal parameters in the macro definition. For more information, see The token-string argument consists of a series of tokens, such as keywords, constants, or complete statements. A given formal parameter may appear more than one time in token-string. Liberal use of parentheses guarantees that complex actual arguments are interpreted correctly. Any macros in the actual argument are expanded before the directive replaces the formal parameter.
After the macro is defined, each subsequent occurrence of identifier identifier opt,. A second define for a macro with the same name generates a warning unless the second token sequence is identical to the first. . Copyright 2005, 1997, 1991 by Random House, Inc. Microsoft Specific Defining macros and constants with the define preprocessing directive at the start of your file. In other words, the two definitions can have different parameter names. The formal parameters in the list are separated by commas.
. . For example, the following two macros are identical except for the parameter names. Each name in the list must be unique, and the list must be enclosed in parentheses. The scope of a formal parameter name extends to the new line that ends token-string. This form accepts an optional list of parameters that must appear in parentheses.
No spaces can separate identifier and the opening parenthesis. A define without a token-string removes occurrences of identifier from the source file. Feedback In this article The define creates a macro, which is the association of an identifier or parameterized identifier with a token string. That is, identifier is not replaced if it appears in a comment, in a string, or as part of a longer identifier. . Each formal parameter in token-string that is not preceded by a stringizing , charizing , or token-pasting operator, or not followed by a operator, is replaced by the corresponding actual argument.
See If the name of the macro being defined occurs in token-string even as a result of another macro expansion , it is not expanded. The number of arguments in the call must match the number of parameters in the macro definition. After the macro is defined, the compiler can substitute the token string for each occurrence of the identifier in the source file. . The identifier is replaced only when it forms a token. Formal parameter names appear in token-string to mark the locations where actual values are substituted. When a macro has been defined in the second syntax form, subsequent textual instances followed by an argument list indicate a macro call.
Syntax define identifier token-string opt define identifier identifier opt ,. The second syntax form defines a function-like macro with parameters.
