Use any C program without using PTHREADS calculate time taken to execute program.

  1. Write same program of question 1 using PTHREADS. Calculate time taken to execute program.(1 mark)
  2. Identify data races in above program and explain why this situation occurred with an example (1 mark)
  3. Rewrite the code to avoid data races should use any of the THREE techniques.(1.5 marks)

please I need the c code..

Using C Write a program that will serve as a simple shell. This shell will execute an infinite for loop. In each iteration of the loop, the user will be presented with a prompt. When the user enters a command, the shell will tokenize the command, create a child process to execute it and wait for the child process to be over. If the user enters an invalid command, the shell should recognize the situation and show a meaningful message....

(using C in a Linux environment and the POSIX pthreads library) Write a program named Sort.c that accepts a list of numbers from the user. There are two threads: Main thread waits for the numbers to be entered by the user and for the second thread to finish sorting. It then asks user whether there are more lists or not. It will do this until the user indicates there are no more lists to be entered, at which point it...

I need to write a C++ program that appends "not" into the string without using the append method or any standard libraries. It should return the string if there isn't an "is" in it. Examples: is is = is not is not This is me = This is not me What is yellow? = What is not yellow? The sky is pink = The sky is not pink isis = isis What happened to you? = What happened to you?

Write a C++ program to calculate the time to drain a cylindrical water tank for an initial water height ranging from 1 to 10 feet (specifically for 1, 2, 4, 6, 8, and 10 ft). The tank has a radius (rt) of 2 feet and the drain radius (rd) is 0.3 inch. The gravitational constant (g) is 32.2 feet/sec2. The formula for time to drain the tank is time=(rtrd)2h/vavg where, average velocity, vavg=0.5(2gh).5 In your program, assign the values to...

Write a C program without using if-else construct that does the following. It accepts a sequence of positive integers between 1 and 9 both inclusive from the keyboard. The program will stop accepting input once an integer outside the range is entered. The program will finish by printing the total number multiples of 3 and total number of even integers entered. Test data and expected output: Enter integers between 1 & 9 both inclusive, outside range to stop Enter integer...
