C Program: Write a program that: As its input arguments, accepts a program name followed by any number of command line arguments for that program. Creates a child process that executes the given program, passing all the provided arguments to it. Once the execution of the child process finishes, the parent process receives the child process exit code (X) and prints Exit code was X to the standard error device.

int x; int* intPtr; Write a C++ program that contains five more statements. The first statement makes intPtr point to x by using the address-of operator. The second statement dereferences intPtr and stores the value 5 into x via indirect addressing. The third statement prints the actual memory address of where the variable x is stored. The fourth prints the contents of intPtr. The fifth prints the contents of x. Show your source code and program output.
