Consider the following code: int main() {     char *s = strdup("This is a  test");     char *d = " ";     while (s) {         char *token = strsep(&s, d);         puts(token);     }     free(s);     return 0; } Which of the following causes an error or segmentation fault? A. free is called on a pointer that was not malloc'ed B. strsep must be called with s instead of &s C. The while loop is an infinite loop D. The string s points to is in read-only memory E. Something else

Concept of Pointer Parameter

Pointers are the special variable that stores the variable address, instead of storing the variable value. Pointer is a powerful feature of a programming language. A pointer is mostly used to save memory space and improve execution time.
