convert float in char array with atof C++

Question

I've been looking for similar problems but am still unable to find a solution to my problem.

I am taking a text file and converting it to a binary file to be used in another program. The other program compiles and outputs everything just fine but the problem seems to lay in my file conversion.

void makefile( ifstream & fi, ofstream & fo ){
    struct{
        int acct;
        char name[25];
        float dolr;
    } x;

    int i;
    char line[81], *p, *q;

    while ( fi.getline( line, 81 ) ) {
        x.acct = atoi( line );
        p = line;
       while ( *p++ != ' ' );
        for ( q = x.name, i = 24 ; i-- ; ){
            *q++ = *p++;                    // *q = '\0';
        }
        while ( *--q == ' ' );              // find end of string

        *++q = '\0';                        // mark end of name string
        x.dolr = atof(p);
        fo.write( (char*)&x, sizeof(x) );
    }
}

The input text file looks like this...

000027183 Hun, Attila The       1234.56
000012345 Dooright, Dudley      211.22
000031416 Whiplash, Snidely     1200.00
000014142 Jekyll, Doctor        1500.00
000031623 Hyde, Mister          1500.00
000010203 Bear, Smokey The      2000.00
000020103 Dumpty, Humpty        3000.00
000030102 Woman, Wonder         3824.36
000030201 Hulnk, Incredible     9646.75
000022345 Snowman, Abominable   2496.24

When I run the program and I check the binary (using a separate program) I can see the converted file but it looks like this:

 27183  Hun, Attila The         1234.56         0.00
 12345  Dooright, Dudley        211.22         0.00
 31416  Whiplash, Snidely       1200.0        0.00
 14142  Jekyll, Doctor          1500.00          0.00
 31623  Hyde, Mister                1500.00           0.00
 10203  Bear, Smokey The        2000.00        0.00
 20103  Dumpty, Humpty          3000.00          0.00
 30102  Woman, Wonder               3824.36          0.00
 30201  Hulnk, Incredible       9646.7        5.00
 22345  Snowman, Abominable     2496        0.24

This was originally written in C and I'm beginning to wonder if that reflects in the code that my professor has given us to make the binary file. Any suggestions?

Update: This is the the function in the other program that reads the file to "check it"

void
chkfile( ifstream & f ){

struct {
    int acct;
    char name[25];
    float dolr;
} x;


while ( f.read( (char *)&x, sizeof(x) ) ){
    cout << setfill('0') << setw(9) << x.acct << "  ";
    cout.setf( ios::left, ios::adjustfield );
    cout << setfill(' ') << setw(26) << x.name;
    cout.setf( ios::right, ios::adjustfield );
    cout.setf( ios::fixed, ios::floatfield );
    cout.setf( ios::showpoint );
    cout.precision(2);
    cout << setw(10) << x.dolr << '\n';
}
}

UPDATE: Turns out the problem was not in the code but in the text file used to create the binary file. I was using tabs to space between names and amounts so the parsing was off when converting to binary. I used blank spaces and that solved my problem!
