Re: [algogeeks] Explain the output
print statement become
printf(char *str= %c%s%c; main...,34,str,34);
now 34 is ascii value of double quote so first %c will get value
ascii_code_of(34) and %s will get same string and last %c again get
ascii_code_of(34) i.e so total string is char *str=+
asci(34)+str+ascii(34)+;main() { printf(str,34,str,34);}

Re: [algogeeks] Explain the output of this code:
*p[] is an array of pointers pointing to the address of array a[] .. i.e
p[0] pointing to a[0]..p[1] to a[1] and so on.
*pp is a pointer to a pointer. It is storing the address of array of
pointers p.
1. *pp gives value at pointed by p[0]. This is 'a'. So when 'a' is
subtracted from it, it returns 0.
2. pp gives the address of pointer p. This is same as 'p' as it also
denotes address of pointer p. Therefore 0 again.
3. **pp gives value at pointer p[0]. That is it gives value a[0] which is 0.
pp++, ++p, *++p ..all these increment address of pp pointing to and not
the value.
So, it increments pp to +4 address of what it was previously pointing to.
4. pp-p means subtracting address of old pp and new pp, which must be four
as address p+4 = address new pp.
5. (*pp -a) means subtract value where pp is pointing -'a' . As pp is
incremented 4 times, it is pointing to 'a+4' . So ans is a+4-a which is 4.
6. Lastly, **pp gives the value of address stored at (*p) i.e. *(a+4) which
is a[4]. Value of a[4] = 4 and so in the answer ;)

Re: [algogeeks] explain the output please.....
* im using devc compiler * when if(ci) is encountered since integer has higher precedence over char ,so char is type casted to int so, (ci) is equivalent to (-64-32) which is false ,so fail1 is printed, -16 is converted to 4,294,967,295 - 16=4,294,967,280(so it is unsigned now) for(iu) integer i is converted to unsigned int so (unsigned int)i=4,294,967,264 so(iu)==(4,294,967,2644,294,967,280) is true so output is pass2 http://stackoverflow.com/questions/5563000/implicit-type-conversion-rules-in-c-operators http://h30097.www3.hp.com/docs/base_doc/DOCUMENTATION/V40F_HTML/AQTLTBTE/DOCU_067.HTM (plz correct me if im wrong) -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

#define SIZEOF(arr) (sizeof(arr)/sizeof(arr[0])) gives the number of

Re: [algogeeks] Explain the output
@jitendra u got it right but parent and child are using the same text region
that's why control is transferring back and forth..
try running this code and see that line numbers are repeating...because of
same text region it is working like a loop...
#includestdio.h
int main() {
int id,i;
if((id=vfork())==0) { //child
printf( %d in child\n,__LINE__);
sleep(3);
printf(%d\n,i);
}
else { //parent
printf( %d in parent\n,__LINE__);
scanf(%d,i);
sleep(1);
printf(%d\n,i);
}
return 0;
}

Re: [algogeeks] Explain the output
changing vfork with fork gives the correct output but in case of vfork the loop behaviour is unpredictable @harit : I guess the child is simply reading the value of i from the same data area of the parent. First time it showed a garbage, after which it shows the value inputted in the parent. If i am not wrong the child uses text and data area of parent till a exec is not been called in the child. Here in the program parent and child are not doing any tweak with the text area then how can we explain the loop behaviour of the program. -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.
