Few questions you should ask the HR : What kinds of assignments might I expect the first six months on the job? How often are performance reviews given? Please describe the duties of the job for me. What products (or services) are in the development stage now? Do you have plans for expansion? What are your growth projections for next year? Have you cut your staff in the last three years? Are salary adjustments geared to the cost of living or job performance? Does your company encourage further education? How do you feel about creativity and individuality? Do you offer flextime? What is the usual promotional time frame? Does your company offer either single or dual career-track programs? What do you like best about your job/company? Once the probation period is completed, how much authority will I have over decisions? Has there been much turnover in this job area? Do you fill positions from the outside or promote from within first? Is your company environmentally

1 . void main(){ int const * p=5; printf("%d",++(*p)); } Answer: Compiler error: Cannot modify a constant value. Explanation: p is a pointer to a "constant integer". But we tried tochange the value of the "constant integer". 2. main() {  char s[ ]="man"; int i;  for(i=0;s[ i ];i++) printf("\n%c%c%c%c",s[i],*(s+i),*(i+s),i[s]); } Answer: mmmm aaaa nnnn Explanation: s[i], *(i+s), *(s+i), i[s] are all different ways of expressing the same idea. Generally array name is the base address for that array. Here s is the base address. i is the index number/displacement from the base address. So, indirecting it with * is same as s[i]. i[s] may be surprising. But in the case of C it is same as s[i]. 3 . main(){  float me = 1.1;  double you = 1.1;  if(me==you) printf("I love U"); else printf("I hate U"); } Answer: I hate U Explanation : For floating point numbers (float, double, long double)

Answer : According to the language definition, a constant 0 in a pointer context is converted into a null pointer at compile time. That is, in an initialization, assignment, or comparison when one side is a variable or expression of pointer type, the compiler can tell that a constant 0 on the other side requests a null pointer, and generate the correctly-typed null pointer value. Therefore, the following fragments are perfectly legal: char *p = 0; if(p != 0) However, an argument being passed to a function is not necessarily recognizable as a pointer context, and the compiler may not be able to tell that an unadorned 0 "means" a null pointer. For instance, the Unix system call "execl" takes a variable-length, null-pointer-terminated list of character pointer arguments. To generate a null pointer in a function call context, an explicit cast is typically required: execl("/bin/sh", "sh", "-c", "ls", (char *)0); If the (c
