char *studentName; is a pointer to a string. What does it point to? Absolutely nothing and nowhere in particular. It might point to invalid memory and crash immediately. It might point to somewhere in your own stack frame, causing it to crash later in fascinating nondeterministic ways.
The correct solution would be to either
1) Use line 8
2) Point it to valid memory with a line like list[x].studentName=malloc(20);

If one wants to get a start address of a array or a string or a block of memory via a function, there are at least two methods to achieve it:
(1) one is to pass a pointer-to-pointer parameter, like:
int my_malloc(int size, char **pmem)
{
*pmem=(char *)malloc(size);
if(*pmem==NULL)... (11 Replies)

scanw
mvscanw(3XCURSES) X/Open Curses Library Functions mvscanw(3XCURSES)
NAME
mvscanw, mvwscanw, scanw, wscanw - convert formatted input from a window
SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib
-R /usr/xpg4/lib -lcurses [ library... ]
c89 [ flag... ] file... -lcurses [ library... ]
#include <curses.h>
int mvscanw(int y, int x, char *fmt, ...);
int mvwscanw(WINDOW *win, int y, int x, char *fmt, ...);
int scanw(char *fmt, ...);
int wscanw(WINDOW *win, char *fmt, ...);
PARAMETERS
y Is the y (row) coordinate of the position of the character to be read.
x Is the x (column) coordinate of the position of the character to be read.
fmt Is a scanf() format string.
win Is a pointer to the window in which the character is to be read.
DESCRIPTION
These functions are similar to scanf(3C). Their effect is as though mvwgetstr(3XCURSES) were called to get a multi-byte character string
from the current or specified window at the current or specified cursor position, and then sscanf() were used to interpret and convert that
string.
RETURN VALUES
Upon successful completion, these functions return OK. Otherwise, they return ERR.
ERRORS
No errors are defined.
