C++: PLEASE HELP

In this lab, please implement quick sort algorithm. This executable file reads integers from an input file, which is given at command line. The imported integers are stored in an internal int array. You can make the array size to be 5000. In other words, we assume the input data file can have at most 5000 integers. After importing the integers from the data file, the main() function calls the quick sort function, then main() function prints out the result.

Once you finish the coding, type the following command to compile it.

g++ lab12.cpp o lab12

The result should be:

Quick Sort Result is:

12 32

33 43 54 75 78 234 243 312 543 636 8567 8976 

quickSort():

void quickSort(int arr[], int left, int right) {

}

main():

int main(int argc, char* argv[]){ fstream input(argv[1]);

int vals[5000];

}
