Memory Fault,Core dumped

I have written a code in UNIX which is complied by using g++. Compling with turbo C didnt yield any errors, but with g++ I am getting Memory fault, core dumped. Could anyone help me out with this?

Given below is the code:

Code:
#include<stdio.h>

#include<string.h>
#include<stdlib.h>
#include<ctype.h>
main()
{
long int lt;
int i,r=0,p,m=0,q=0;
char a[100];
char *str;
//a=(char*) malloc(sizeof(char) *100);
str=(char *)  malloc(sizeof(char) *100);


scanf("%s",str);
p=strlen(str);
for(i=0;i<p;i++)
{
        if(isdigit(str[i])==0)
        {
        if((str[i]!='.')&& str[i]!='-')
       {
        m=1;
        }
        }
}
for(i=0;i<=p;i++)
{
        if(str[i]=='-')
        r=r+1;
}
for(i=0;i<=p;i++)
{
        if(str[i]=='.')
        q=q+1;
}
lt=atol(str);
if(p>=16 || strcmp(str,NULL)==0 || m==1 || r>1 ||q>1 || lt==0)
{
printf("ERROR");
}
else
{
//ltoa(lt,a,10);
sprintf(a,"%l",lt);
printf("%s",a);
}
}

curs_instr(3X)															    curs_instr(3X)

NAME
instr, innstr, winstr, winnstr, mvinstr, mvinnstr, mvwinstr, mvwinnstr - get a string of characters from a curses window SYNOPSIS
#include <curses.h> int instr(char *str); int innstr(char *str, int n); int winstr(WINDOW *win, char *str); int winnstr(WINDOW *win, char *str, int n); int mvinstr(int y, int x, char *str); int mvinnstr(int y, int x, char *str, int n); int mvwinstr(WINDOW *win, int y, int x, char *str); int mvwinnstr(WINDOW *win, int y, int x, char *str, int n); DESCRIPTION
These routines return a string of characters in str, extracted starting at the current cursor position in the named window. Attributes are stripped from the characters. The four functions with n as the last argument return a leading substring at most n characters long (exclu- sive of the trailing NUL). RETURN VALUE
All of the functions return ERR upon failure, or the number of characters actually read into the string. X/Open defines no error conditions. In this implementation, if the window parameter is null or the str parameter is null, a zero is returned. NOTES
Note that all routines except winnstr may be macros. PORTABILITY
SVr4 does not document whether a length limit includes or excludes the trailing NUL. The ncurses library extends the XSI description by allowing a negative value for n. In this case, the functions return the string ending at the right margin. SEE ALSO
curses(3X). curs_instr(3X)
