hello,

I am working on my project and I am getting an Infinite loop when entering a character

what did I do wrong here?

#include #include #include

using namespace std;

class Student { public: Student(); Student(string, int, char); ~Student();

string getName() const; int getAge() const; char getGrade() const;

void setName(string); void setAge(int); void setGrade(char);

private:

string newName; int newAge; char newGrade;

}; void fillVector(vector& infoClass); void deleteVector(std::vector& studentInfo); void printVector(const vector& studentInfo);

/**************************** * Function: main * Description: The main control. allow to enter and use as much it wants. *****************************/ int main() { vectorinfoClass; int pick; //ask student to enter the options cout << "Please enter your number to pick your options" << endl; cout << "1: Add\t2: View\t 3:Delete 4:Exit" << endl; //let students read the options cout << "Enter your choice: "; cin >> pick; while (1) { switch (pick) { case 1:fillVector(infoClass); cout << "your information added! " << endl; break; case 2: printVector(infoClass); break; case 3: deleteVector(infoClass); break; case 4: exit(0); cin.clear(); default:cout << "Invalid choice." << endl; }

//again read the user choice until user presses exit button cout << endl << "1: Add\t2: View\t3:Delete 4:Exit" << endl; cout << "Enter your choice:"; cin >> pick; cout << endl; }

return 0; }

/**************************** * Function: fillVector * Description: let the function to read the values and add the vector *****************************/ void fillVector(vector& infoClass) { string name; int age; char grade; cout << endl << "Enter your name: "; cin.ignore(); getline(cin,name); cout << "Enter your age: "; cin >> age; cout << "Enter your Grade: "; cin >> grade; Student infoStudent(name, age, grade); infoClass.push_back(infoStudent); cout << endl; } /**************************** * Function: deleteVector * Description: let the function to delete the objects *****************************/ void deleteVector(std::vector& studentInfo) { if (studentInfo.size() == 0 ) { cout << "Unable to delete please enter your information first" << endl; cin.clear(); } else { string name; cout << "Please enter a valid name on your info to remove: "; cin.ignore(); getline(cin, name); int error = 0; string deleteName; vector::iterator it; int i = 0;

for (i = 0; i < studentInfo.size(); i++) { deleteName = studentInfo[i].getName();

if (deleteName == name) { error = 1; break; } } if (error == 0) cout << endl << "Unable to find your name in the system" << endl; else { studentInfo.erase(studentInfo.begin() + i); cout << endl << "your infomation is deleted." << endl; } } } /**************************** * Function: printVector * Description: let the function read *****************************/ void printVector(const vector& studentInfo) { if (studentInfo.size() == 0) { cout << "should not be blank please enter again" << endl; cin.clear(); } else { cout << "Student Name \ Student age\ Student Grade" << endl; for (int i = 0; i < studentInfo.size();i++) { cout << studentInfo[i].getName() << "\t\t" << studentInfo[i].getAge() << "\t\t" << studentInfo[i].getGrade() << endl; } } }

Student::Student() { newName = ""; newAge = 0; newGrade = ' ';

}

Student::Student(string name, int age, char grade) { newName = name; newAge = age; newGrade =grade; }

Student::~Student() { } string Student::getName() const { return newName; }

int Student::getAge() const { return newAge; }

char Student::getGrade() const { return newGrade; }

void Student::setName(string name) { newName = name; }

void Student::setAge(int age) { newAge = age; }

void Student::setGrade(char grade) { newGrade = grade; }
