Question

Write a C++ program to demonstrate thread synchronization. Your main function should first create a file called synch.txt. Then it will create two separate threads, Thread-A and Thread-B. Both threads will open synch.txt and write to it. Thread-A will write the numbers 1 - 26 twenty times in nested for loops then exit. In other words, print 1 - 26 over and over again on separate lines for at least 20 times. Thread-B will write the letters A - Z twenty times in nested for loops then exit. You must use a mutex lock to control synchronization between the two threads. When the program is complete, the synch.txt file should look like this: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 ..... 20x A B C D E F G H I J K L M N O P Q R S T U V W X Y Z A B C D E F G H I J K L M N O P Q R S T U V W X Y Z A B C D E F G H I J K L M N O P Q R S T U V W X Y Z ... 20x
