Write one C program to measure the average time to create a thread using pthread_create() and to create a process using fork().
1. Use a for loop to create 300 threads using pthread_create(), and measure the total time to create these 300 threads. Then compute its average;
2. Use a for loop to create 300 processes using fork(), and measure the total time to create these 300 processes. Then compute its average;
Briefly describe the reasons for the difference in timings.
It needs to use gettimeofday() to retrieve the system time.
