My code seems to ask twice instead of once if I want to run the code again. I just want it to run normally like my other cases which only ask once after I have viewed the activity and these two activities are the only ones with problems. What seems to be the problem here:

case 5:

cout<<"Here are the list of activities in Activity 5:" << endl;

cout<<"[5.1]Determining a Number within the Array" << endl;

cout<<"[5.2]Determining the Highest and Lowest integer" << endl;

cout<<"[5.3]Reversed Array" << endl;

cin >> choice;

system("CLS");



        if(choice == 5.1){

            counter +=1;

            int nos[10];

            int det;

            cout <<"Note: Do not input any decimal numbers." << endl;

                for(int array = 1; array < 11; array++){



                    cout << "Input integers 1-10 only. [" << array << "]";

                    cin >> nos[det];

                                        }

                    cout << "Type in 1 integer value only.[" << det << "]";

                    cin >> det; 



                    if(det >= nos[1] || det <= nos[10]){

                        cout << "The value is within the scope of the array.";

                                        }

                    else{

                        cout << "The value is not within the scope of the array.";

                                        }

        system ("PAUSE");

        system ("CLS");

            cout << "Do you want to run the program again? (y/n)" << endl;

            cin >> choose;

                        }



        else if(choice == 5.2){

            counter +=1;

        cout <<"Note: Do not input any decimal numbers." << endl;

        cout <<"Enter your integers." << endl;

        int nos[10];

        int put;

                for(int rep = 1; rep < 11; rep++){



                    cout <<"[" << rep << "]";

                    cin >> nos[rep];

                            }

                        int highnos = nos[1];

                        int lownos = nos[1];



                for(int rep = 1; rep < 11; rep++){

                if(nos[rep] > highnos){

                    highnos = nos[rep];

                                                    }           

                            }                           

                    cout << "Your highest integer is:" << highnos << endl;



                for(int rep = 1; rep > 11; rep++){

                if(nos[rep] < lownos){

                lownos = nos[rep];

                                    }

                                                }

        cout <<"Your lowest integer is:"<< lownos << endl;

            system ("PAUSE");

            system ("CLS");

            cout << "Do you want to run the program again? (y/n)" << endl;

            cin >> choose;



                                }

P.S. my activities also has errors but dont mind it :D

First of all, you haven't initialized anything so everything is taking garbage values.
initialize det first and if you want to input the whole array then run a loop. cin>>nos[det] only inputs one value at a garbage index according to your code.

This code is a mess. Kindly fix initializations and inputs, then share the output you're getting vs the output you want.
