Write a C program to implement SJF algorithm.Shortest Job First(SJF) is the CPU scheduling algorithm. In SJF, if the CPU is available it allocates the process which has smallest burst time, if the two process are same burst time it uses FCFS algorithm.Read more about C Programming Language . and read the C Programming Language …
Write a C Program to lock file using semaphores.Using semaphores, We can control access to files, shared memory and other things. The basic functionality of a semaphore is that you can either set it, check it, or wait until it clears then set it (“test-n-set”). In C semaphores functions defined in the sys/sem library. Read …
Write a C Program to delete a file.To delete a file in c, We use the remove macro, which is defined in stdio.h. remove macro takes filename with extension as its argument and deletes the file, if it is in the directory and returns the zero, if deleted successfully.Note that deleted file does not goes …
Write a C Program to demonstrate strspn function.The strspn() function returns the index of the first character in string1 that doesn’t match any character in string2. If all the characters of the string2 matched with the string1, strspn returns the length of the string1.
