i have a pointer that it aint working. plz help.

wut is the problem with the pointer???. the compiler doesnt find an error but when i run it it gives me an illegal operation and i have to close it. any ideas??

Code:

---

void newperson ()
{
        int count, numppl;
        char *strp;
        *strp = input[20];
        cout<<"How many people do you want to introduce?"<<endl;
        cin>>numppl;
        for (count=0 ; count <=numppl ; count=count +1)
        {
                cin.get (input, 20);
        }
}

---

thx

if input is global then the code should work but if it is not the case then u should pass it to the function or declare it in the function.it also depends upon the data types of the pointer and input.they should be same!

*strp = input[20];
You don't know on what address this is getting assigned.
Your program might overwrite anything radomly. Lucky for you your OS is stoping this from happening.

int i;
int *p;
p = &i; //You must do this. p is pointing to the address of i.

i did wut u told me to barjor. i have now:

Code:

---

char *strp;
.
.
.
void newperson ()
{
        int count, numppl;
        strp = agendaarray;
        cout<<"How many people do you want to introduce?"<<endl;
        cin>>numppl;
        for (count=0 ; count <=numppl ; count=count +1)
        {
                cin.get (agendaarray, 20);

        }
}

---

//I changed the input array for agendaarray.
the error i get is ::

Put the varaibles inside the function

your original code was fine except for one minor thing. you must first assign strp to input. like this:

Code:

---

void newperson()
{
        int count, numppl;
        char *strp=input;
        *strp = input[20];
        cout<<"How many people do you want to introduce?"<<endl;
        cin>>numppl;
        for (count=0 ; count <=numppl ; count=count+1)
        {
                cin.get (input, 20);
        }
}

---

just add the '=input' after 'char *strp'

now it runs fine. except for one major thing. the cin.get (input, 20); does not read anything. it skips that part and keeps going with my program.

Code:

---


void newperson()
{
        int count, numppl;
        char *strp=input;
        *strp = input[20];
        cout<<"How many people do you want to introduce?"<<endl;
        cin>>numppl;
        for (count=0 ; count <=numppl ; count=count+1)
        {
                cin.get (input, 20);
        }
}

I wonder if i havet to make the "void" into a char newperson (void) and place a return input[20];

plz reply if u have an idea. thx

Code:

---


void newperson ()
{
        int count, numppl;
        cout<<"How many people do you want to introduce?"<<endl;
        cin>>numppl;
        char *strp=new char [numppl+1];
                for (count=0 ; count <=numppl ; count=count +1)
        {
                cin.get (input, 20);
        }
}

And at the end of the program, write delete [] strp;
