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.
#include<iostream>
#include<cstdlib>
using namespace std;
int main() {
int ans,x,z;
string name, data[100][5];
bool found;
x = 0;
do {
found = false;
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:
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:
z = x;
cout << "Presenter name: ";
cin >> name;
do {
if (name==data[z-1][0]) {
found = true;
cout << "Name: " << data[z-1][0] << endl;
