.
why name is there when it is a char, and how can it be > 1?? And it works fine if i remove it.

if (name != NULL && namemax > 1))

if (name && namemax > 1)

if ( (name != 0) && (namemax > 1) )

if (anything)

i corrected that it still doesn't work.

int c;
int namelen = 0;  // initialize array position index to zero
do {
   c = getc(stdin);  // fetch the integer keyboard read value .. EOF safe
   temp.name[namelen++] = (char) c;  // convert the integer to a char and place in array .. increment position
} while (c !=EOF && c != '\n');  // repeat until EOF or new line
temp.name[namelen-1] = '\0';  // Make C null terminated string (overwrite last EOF or '\n')
