Given with the threads the program must print the thread based on their priorities starting from 0 to 10.What is a thread?Thread is lightweight process that runs inside a program. A simple program can contain n number of threads.Unlike java, multithreading is not supported by the language standards, POSIX Threads (Pthreads) is the standard used in multithreading in C/C++. C does not contain any built-in support for multithreaded applications. Instead, it relies entirely upon the operating system to provide this feature.How it works in our program?To use the thread functions we use header file #include. This header file will include ...
