Can someone explain the segmentation fault
#include<stdio.h>
#include<string.h>
int main()
{
char *s1="hello1";
char *s2="hello2";
{
strcpy(s1, s2);
printf("%s\n", s1);
}
}
[EMAIL PROTECTED] ~/CSSp08]$ ./a.out
Segmentation fault (core dumped)- can occur during the operation of computer
software. A segmentation fault occurs when a program attempts to access a
memory location that it is not allowed to access
