C++ please use file names below **LAB: File Statistics**### Task Overview:Create a program that provides a menu offering several file operations:- **L**: Find the lowest value in a file- **H**: Find the highest value in a file- **A**: Find the average value in a file- **Q**: Quit the programPrompt the user with:```Choose:```### Program Behavior:- **Invalid Choice**: If an invalid option is chosen, display: ``` Invalid choice. Re-enter: ```- **Valid Choice**: - Prompt for a file name: ``` Enter input file name: ``` - Read the file and output the requested value: - **Highest value**: ``` Highest value is 0 ``` - **Lowest value**: ``` Lowest value is 0 ``` - **Average value**: ``` Average value is 0 ```- **File Error**: - If the file is empty or cannot be opened, show: ``` File empty or could not open file ```- **Quit**: If "Q" is selected, print "Exiting" and end the program.### Additional Requirements:- **Prohibited**: Arrays are not allowed.- **Required Functions**: Implement these functions, taking a string (filename) and passing a double by reference. Return a bool indicating success (non-empty file) or failure: ```cpp bool averageFromFile(string filename, double& value) bool lowestFromFile(string filename, double& value) bool highestFromFile(string filename, double& value) ```### Files:- **Downloadable files**: - empty.txt - in.txt*Ensure all requirements are met to avoid losing points.*

Here I written C++ code for given problem below. I hope you like it.Code: code with comments for better understanding. #include <bits/stdc++.h> using namespace std; bool averageFromFile(string fnam, double &avrg){//here open file in read mode fstream finp; finp.open(fnam); int total_sc = 0; //here if file exits then open or error if(!finp) { cout<<"File empty or could not open file"<<endl; return false; } else { avrg = 0; double sc; while(finp>>sc) { avrg+=sc; total_sc+=1; } //here Calculate avrg and close the file avrg = (double)avrg/total_sc; finp.close(); return true; }} bool lowestFromFile(string fnam, double &lowst){ //here open file in read mode fstream finp; finp.open(fnam); //here if file exits then open or error if(!finp) { cout<<"File empty or could not open file"<<endl; return false; } else { // here Read first value in variable lowst finp>>lowst; double sc; // here Read scores from file while(finp>>sc) { if(lowst>sc) { lowst = sc; } } //here close file and return true finp.close(); return true; }} bool highestFromFile(string fnam, double &hiest){ //here open file in read mode fstream finp; finp.open(fnam); //here if file exits then open or error if(!finp) { cout<<"File empty or could not open file"<<endl; return false; } else { // here Read first value in variable hiest finp>>hiest; double sc; // here Read scores from file while(finp>>sc) { if(hiest<sc) { hiest = sc; } } //here close file and return true finp.close(); return true; }}//here define main methodint main(){ //define variables char choice = 'L'; string fnam; double avrg; double lowst, hiest; //here whileloop for user input Q to quiet loop while(choice!='Q' && choice!='q') { //here Show menu as per problem cout<<"L->Find lowst value in a file"<<endl; cout<<"H->Find hiest value in a file"<<endl; cout<<"A->Find avrg in a file"<<endl; cout<<"Q->Quit "<<endl; cout<<"Enter your Choose: "; cin>>choice; // if choice L then call this if(choice=='L' || choice=='l') { cout<<"Enter input file name: "; cin>>fnam; if(lowestFromFile(fnam,lowst)) { cout<<"Lowest value is "<<lowst<<endl; } } //if if choice H then call this else if(choice=='H' || choice=='h') { cout<<"Enter input file name: "; cin>>fnam; if(highestFromFile(fnam,hiest)) { cout<<"Highest value is "<<hiest<<endl; } } //if choice A then call this else if(choice=='A' || choice=='a') { cout<<"Enter input file name: "; cin>>fnam; if(averageFromFile(fnam,avrg)) { cout<<"Average value is "<<avrg<<endl; } } // here Q or q, print Exiting else if(choice=='Q' || choice=='q') { cout<<"Exiting\n"; } // Else, print invalid choice else { cout<<"Heyy Invalid choice please try again"<<endl; } } return 0;}Screenshot of code with editorOutput Test Case1: TestCase2
