Reading in numbers and names using getline in C++?

Question

So I've been working on this problem for hours now and I would like to get some help. I have a program due tomorrow. Basically, I have an input file that has a first and last name and then four float numbers following. It looks like this:

John W.
Smith
78.8 56.5 34.5 23.3
Jane 
Doe
34.5 23.4 35.7 87.0
No

I need to read the first and last names into an array of pointers. So far I am just trying to read in each line to the variable "name" and I'm outputting to a text file to see if I have been reading in the data correctly. Unfortunately, it stops after it reads in the floats, it doesn't read in the next names.

char *newPtr;               
char *nameList[50] = {0};   
char name[15];  
int i = 0; 
infile.getline(name, 15);

while (strcmp (name, "No") != 0)
{
    newPtr = new char[15];
    strcpy(newPtr, name);
    nameList[i] = newPtr;
    infile.getline(name, 15);
    outfile << name << endl;
    i++;
}

So far, the output has just been:

John W.

Smith

78.8 56.5 34.5 23.3

EDIT: The loop is currently infinite, but from my output, I know that I haven't actually processed the second names yet, I stop at the first numbers.

If I could get some help, it would be great! I am very limited to the functions I can use, I am certain I should just be using the getline function here, I cannot use anything fancy.

In her slides, my teacher has this code here to help us with reading in names:

char *newPtr;
char *NameList[6] = {0};
char Name[20];
int a = 0;
infile.getline(Name, 20);
while(strcmp(Name, sentinel) != 0)
{
newPtr = new char[20];
strcpy(newPtr,Name);
NameList[a++] = newPtr;
infile.getline(Name,20);
}

We have not been taught about strings yet and I am certain I cannot use what we have not talked about in class. Thank you for the help so far everyone who has commented.

You're nearly there... main thing was you forgot to attempt to read the numbers. The code below reads them into w, x, y and z but then ignores them... you should do whatever you need to with them, e.g. probably create a second array for the surnames and either a third 2-dimensional array for the floats or a 1-dimensional array 4 times as long....

char *nameList[50] = {0};   
char name[15];  
int i = 0; 

while (infile.getline(name, sizeof name) && strcmp(name, "No") != 0)
{
    char* newPtr = new char[sizeof name];
    strcpy(newPtr, name);
    nameList[i] = newPtr;
    double w, x, y, z;
    if (infile.getline(name, sizeof name) && infile >> w >> x >> y >> z)
        outfile << name << endl;
    else
    {
        std::cerr << "missing rest of data for " << nameList[i] << " found\n";
        exit(EXIT_FAILURE)
    }
    i++;
}
