We want each of the two threads in the code below to print the numbers from 5-10. With the current code this is not working as both threads use the same counter in the while loop. Sometimes we want each thread to have it's own copy of a variable, when this is desired we can use OpenMPs private clause to give each thread it's own instance.

Knowledge

To mark a variable as private you add private(var1, var2) to your directive. Some directive such as the omp for directiv assume certain variables as private by default. In the omp for example it is the loop counter. Thats why you didn't had to specify a private varible befor.

Task

Add a private clause to the code, so that both threads output the numbers 5 to 10.
