C++ program to register data from presenters for colleges, using a menu interface and array-type data structure. Below is an image of the code.

C++ code

#include<iostream>

#include<cstdlib>

using namespace std;

int main() {

  •   // Define variables

int ans,x,z;

string name, data[100][5];

bool found;

x = 0;

do {

 found = false;

  • // Data menu

 cout << "   Data Menu" << endl;

 cout << "*****************" << endl;

 cout << "1.- Entry" << endl;

 cout << "2.- Change" << endl;

 cout << "3.- Display" << endl;

 cout << "0.- Exit" << endl;

 do {

  cin >> ans;

 } while (!(ans!=1 || ans!=2 || ans!=3 || ans!=0));

 switch (ans) {

 case 1:

  • // Presenter 'personal data

  x = x+1;

  cout << "Name: ";

  cin >> data[x-1][0];

  cout << "Presentation topic: ";

  cin >> data[x-1][1];

  cout << "Address: ";

  cin >> data[x-1][2];

  cout << "Telephone: ";

  cin >> data[x-1][3];

  cout << "Fee required: ";

  do {

   cin >> data[x-1][4];

  } while (atof(data[x-1][4].c_str())<0);

  break;

 case 2:

  • // Changing presenter' data

  z = x;

  cout << "Presenter name: ";

  cin >> name;

  do {

   if (name==data[z-1][0]) {

    found = true;

    cout << "Name: " << data[z-1][0] << endl;

    cout << "New name: ";

    cin >> data[z-1][0];

    cout << "Presentation topic: " << data[z-1][1] << endl;

    cout << "New presentation topic: ";

    cin >> data[z-1][1];

    cout << "Address: " << data[z-1][2] << endl;

    cout << "New address: ";

    cin >> data[z-1][2];

    cout << "Telephone: " << data[z-1][2] << endl;

    cout << "New telephone: ";

    cin >> data[z-1][3];

    cout << "Fee required: " << data[z-1][3] << endl;

    cout << "New fee required: ";

    do {

     cin >> data[z-1][4];

    } while (atof(data[z-1][4].c_str())<0);

   }

   z = z-1;

  } while (!(found==true || z==0));

  if (found==false) {

   cout << "Not found" << endl;

  }

  break;

 case 3:

  • // Display presenter' data

  z = x;

  cout << "Presenter name: ";

  cin >> name;

  do {

   if (name==data[z-1][0]) {

    found = true;

    cout << "Name: " << data[z-1][0] << endl;

    cout << "Presentation topic: " << data[z-1][1] << endl;

    cout << "Address: " << data[z-1][2] << endl;

    cout << "Telephone: " << data[z-1][3] << endl;

    cout << "Fee required: " << data[z-1][4] << endl;

   }

   z = z-1;

  } while (!(found==true || z==0));

  if (found==false) {

   cout << "Not found" << endl;

  }

  break;

 }

} while (!(ans==0 || x>100));

return 0;
