Write one c program to measure the average time to create a thread using pthread_create() and to create a process using

1. use a for loop to create 300 threads using and measure the total time to create these 300 threads. then compute its average;
2. use a for loop to create 300 processes using 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.
