write a c++ program

a sample program that reads from the file in c++

Write a C++ program that forks two child processes:

1- Child 1 process will look for all the C++ programs stored in your home directory and store the searching results in a text file called (CPP_files.txt). (ONE statement ONLY to accomplish this task)

Hint: you need to use (find *.cpp) command, the result of the find command should be stored in the CPP_files.txt file.

2- Child 2 process should reads the content of (CPP_files.txt) file and it should find number of lines in each .cpp file and store the results in a file called Output.txt

Hint: you need to use the ( wc -l ) command.

Child 2 MUST use the execve system call to accomplish its task.

3- At the end, the parent Process should delete the CPP_files.txt file.

A Sample program that reads from file in C++:

#include

#include

// include the fstream (file stream library) using namespace std;

int main()

{ // declaring an input file called infile

ifstream infile;

// opening the input file (file we will read from) that called CPP_files.txt

infile.open("CPP_files.txt");

string str;

// loop to read the content of the file line by line till the end of the file

while(infile>>str) { // display the line we read from the file on the screen (terminal)

cout

infile.close();

return 0; }

1. Child 1 process will look for all the C++ programs stored in your home directory and store the searching results in a text file called (CPP_files.txt). (ONE statement ONLY to accomplish this task) Hint: you need to use (find *.cpp) command, the result of the find command should be stored in the CPP_files.txt file. 2. Child 2 process should reads the content of (CPP_files.txt) file and it should find number of lines in each.cpp file and store the results in a file called Output.txt Hint: you need to use the ( wc -) command. Child 2 MUST use the execve system call to accomplish its task. 3. At the end, the parent Process should delete the CPP_files.txt file.
