Standard library functions. The standard library functions are built-in functions in C programming to handle tasks such as mathematical computations, I/O processing, string handling etc. These functions are defined in the header file. When you include the header file, these functions are available for use.
Knee replacement. Knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability. It is most commonly performed for osteoarthritis,[1] and also for other knee diseases such as rheumatoid arthritis and psoriatic arthritis.
Recovery is quicker than a total knee replacement; usually @6 weeks. After surgery you need to take an antibiotic before any dental or GI procedures and avoid high impact activities. A partial knee replacement involves a resurfacing of one of three parts of the knee (medial, lateral , or patella-femoral compartments). There may be some lateral knee numbness after surgery. Recovery is quicker than a total knee replacement; usually @6 weeks.
