Students have asked these similar questions
char buffer [BUFSIZE];
int fd = open("fooey", O_WRONLY|O_CREAT|O_TRUNC,0777);
strcpy(buffer, "First data");
write(fd, buffer, strlen(buffer));
1seek (fd, 90, SEEK_SET);
strcpy (buffer, "Second data");
write(fd, buffer, strlen(buffer));
1seek (fd, 100, SEEK_END);
strpcy (buffer, "Third data");
write(fd, buffer, strlen(buffer));
close(fd);
a. What is the size of the file at the end of this section of code?
b. Describe the contents of the file say exactly what byte offsets contain actual data, and what
offsets constitute "holes".
c. Why might holey files be useful?
d. Suppose, after the above sequence of writes, the same program opens the file for reading and
then does:
#include <stdio.h>
#include <string.h>
int IsPasswordOkay(char* pass)
{
char Password[12];
strcpy(Password, pass);
if (!strcmp(Password, "goodpass")) return(1);
else return(0);
}
int main(int argc, char **argv)
{
int PwStatus;
if (argc < 2) {
printf("Input your password\n");
return(-1);
}
PwStatus = IsPasswordOkay(argv[1]);
if (PwStatus == 0) {
printf("Acces denied");
return(-1);
}
else {
printf("Access granted");
return(1);
}
}
Write a function to conduct input validation to secure the smallest buffer. You may call this function void SecurePasswordBuffer(const char *arg).
int X[10]={2,0,6,11,4,5,9,11,-2,-1);
From the code above, what is the value of X[8] ?
