Using the program shown below, explain what will be output at Line A. Assume that fork() completes successfully.  #include #include #include   int value = 40; int main() {      pid_t pid;      pid = fork();      if (pid == 0) {             value += 30;      } else if (pid > 0) {             wait(NULL);             printf(“PARENT: value = %d”, value);   //Line A             exit(0);      } }

Zybooks C++ 1.7 LAB: Introduction to data structures labs Step 1: Producing correct output Three commented-out lines of code exist in main(). Uncomment the lines and click the "Run program" button. Verify that the program's output is: 2 + 2 = 4 Unknown function: PrintPlus2 Secret string: "abc" Submit your code for grading. Your submission will pass the "Compare output" test only, achieving 1 of the possible 10 points. Step 2: Inspecting the LabPrinter class Inspect the LabPrinter class implemented in the LabPrinter.h file. Access LabPrinter.h by clicking on the orange arrow next to main.cpp at the top of the coding window. Member functions Print2Plus2() and PrintSecret() print strings using std::cout. Step 3: Implementing CallFunctionNamed() Remove the three uncommented lines from main(). Then implement the CallFunctionNamed() function in main.cpp to handle three cases: If functionName is "Print2Plus2", call printer's Print2Plus2() member function. If functionName is "PrintSecret",…

C++ Question: Make an execution chart like the example below for the code provided. Example chart: An execution chart is a text version of the hierarchy. Indentation is used to indicate thesublevels or calls inside a call. It also contains the data exchange between the components asdesignated in the hierarchy chart. Given below is the execution chart that corresponds to thehierarchy chart of the property tax calculation program1.0 Main()2.0 CalculatePropertyTax()3.0 displayMessage( input string messageToDisplay)3.1 return double getHomeValue()3.2 return boolean checkHomeValue()3.3 return double applyPropertyTax(input double homeValue)3.4 displayPropertyTax(input homeValue)3.5 return Boolean queryMoreData()4.0 displayMessage(input string messageToDisplay)4.1 return char getYesNo()4.2 return char convertCase(input char)3.6 displayErrorMessage() More exlanation: example: 1.0 means it's of depth 1, line 0 then 2.0 means it's one call inside a function (aka it's inside another function)…
