Many programming languages, especially older ones, provide no language support for concurrency. C and C++ are examples of such languages. Is it essential that a language include syntax for concurrency to be able to write concurrent programs in that language? If not, how is it accomplished? What are the advantages and disadvantages of including support for concurrency in a language? Solution Advantages: 1).Although the tasks are running and the user can relate with the applications. 2).It has the availability of services. means long running the tasks will not delay tiny running ones. 3). complex programs make better use of many resources. 4).tasks are requiring certain pre conditions can hang and wait untill the pre conditions are seize and then restart implementation properly. Disadvantages: 1). a chance of corrupting consistent state of program by concurrent tasks. 2).Deadlock may occur. 3).It would be masters exponential number of interleavings due to different schedules..

Solution
Advantages:
1).Although the tasks are running and the user can relate with the applications.
2).It has the availability of services. means long running the tasks will not delay tiny running
ones.
3). complex programs make better use of many resources.
4).tasks are requiring certain pre conditions can hang and wait untill the pre conditions are seize
and then restart implementation properly.
Disadvantages:
1). a chance of corrupting consistent state of program by concurrent tasks.
2).Deadlock may occur.
3).It would be masters exponential number of interleavings due to different schedules.
