Thread: C++ Set and Get help

hi friends, I am new to c++, just learning.
i want the program to access the private member of the class, and have used set and get, and validate when user input. but the program below is not working.
i cant compile it.
can anyone help me, thanks friends.

Code:

#include<iostream>
#include<string>


using namespace std;

class students
{
private :
string name;
string ID;
int age;

public :

string setName(string temp)
{

name = temp;

}
string getName()
{
return name;
}

void setID(int temp)
{

if(temp < 1)
{
cout << " You have enter an invalid ID number ";
exit(1);
}
else
ID = temp;

}

string getID()
{
return ID;
}

void setAge(int temp)
{

if (temp < 1)
{
cout<< " invalid age type"<<"program terminatingt";
exit(1);
}
else if (temp > 150)
{
cout <<" you are not human"<< "program terminating";
exit(1);
}
else
age = temp;

}
int getAge()
{
return age;
}


};

int main()
{
students st;
cout <<" Enter your name : ";
cin >>st.setName();
cout<< "Enter your ID :";
cin >>st.setID();
cout<< " Enter your age :";
cin >>st.setAge();
}

Did you bother to read the error messages you got from the compiler?

Code:

Compiling: H:\temp.cpp
H:\temp.cpp: In function `int main()':
H:\temp.cpp:74: error: no matching function for call to `students::setName()'
H:\temp.cpp:17: note: candidates are: std::string students::setName(std::string)
H:\temp.cpp:76: error: no matching function for call to `students::setID()'
H:\temp.cpp:28: note: candidates are: void students::setID(int)
H:\temp.cpp:78: error: no matching function for call to `students::setAge()'
H:\temp.cpp:46: note: candidates are: void students::setAge(int)

Not only does it tell you which lines have errors, but points out what the functions are supposed to look like.

And please format your code. That is very ugly.
