This question is based on the network layer. Draw diagrams for a scenario where a packet is moving among three nodes, A, B, C (different IP
addresses). The packet is starting from A and going to C, passing via B. For each of the three nodes,
you are required to show the IPV4 packet content. If you cannot do the exact content, explain what
it should contain. Describe the diagrams drawn under the headings A, B, C.

Write code using c . (take input from user) calculate the size of a given file in kbs. in this task you will complete the function with the following prototype: float get_file_size(char * filename); the function takes the file name (address to the start of a null terminated character array) as input. the function should then open the file and find the number of bytes it contains till eof. the number of bytes divided by 1024 will give the size in kbs. if the file cannot be opened the function should return -1.

Experimental data that is expressed using numbers is said to be

3. what is the output of the following statements? temporary object1; temporary object2("rectangle", 8.5, 5); temporary object3("circle", 6, 0); temporary object4("cylinder", 6, 3.5); cout < < fixed < < showpoint < < setprecision(2); object1.print(); object2.print(); object3.print(); object4.print(); object1.set("sphere", 4.5, 0); object1.print();
