The answer is 3 2 3.
Please explain

Where does the definition of printf() lie ?

Given an arry Arr[N] of integers and a function int func(int x) that takes an integer and returns either 0 or 1 (depending on some property of the integer). Give the most efficient algorithm to store the numbers in the array in such a way that all numbers that return 1 should come before all numbers that return 0, when called upon by the function func

How much memory will be allocated from the "stack" for the following declarations together?
int *a;
char *b;

This was an objective question. a and b have not been malloced yet.

int a = 323235,b = 133423,c;
int *p = &a,*q = &b;
c = p - q;
for the snippet above, the value of c is 1. Why is it not the difference of the address values in p and q ?(i.e 4)

A new USB memory device is designed with the following functionalities.

Write the test cases.

write a function to reverse a linked list in the following fashion.
given: a list : a b c d e f
a number N
output should be: if N=2
b a d c f e
if N=3
c b a f e d
ie, the list should be reversed in <N><N>...<N> intervals. We are not allowed to allocate any new nodes.

find the number of solutions (non-negative integral) for the equation x1+x2+x3+x4+x5=20.
ie, #((0,0,0,0,20),(0,0,0,20,0),....)
