What does transport layer do?

Explanation

In the Open Systems Interconnection (OSI) communications model, the Transport layer ensures the reliable arrival of messages and provides error checking mechanisms and data flow controls. The Transport layer provides services for both “connection-mode” transmissions and for “connectionless-mode” transmissions. For connection-mode transmissions, a transmission may be sent or arrive in the form of packets that need to be reconstructed into a complete message at the other end.

What is the output of the Program?

  1. main ()
  2. {
  3.     inta[10];
  4.     a[3] =10;
  5.     printf ( “%d” ,⚹(a +3) );
  6. }

Explanation

Here, in the main () function an integer array is defined, i.e.. a is an integer array of 10 elements. The 3rd element of this array is initialized with 10. In the printf statement we want to print the value at a + 3. Here, a without any argument means a [0] , i.e.. we want to print the value of a [0 + 3] , i.e.. a [3] . As a [3] is initialized with 10 the output of the program will be 10.
