How do you know if a number is Odd or Even?
Write a program to reverse a string and reverse words in a string
How can u swap 2 variables without using temp variable (XOR)

Char abc[10] ;
Strncpy(abc,”abcdefghijklmn”,10);

What r the data types and values of below
Abc
*abc
Abc[5]
Abc+4
&abc[5]
(*abc)+15

Float j=20.5 int i=20
If we say i+j , wat will be value of it..How the compiler treats it

File

Void settime(char* buf); //its defined in some other module

Static char* gettime()
{
Char buf[80];
Settime(buf);
Return buf;
}

Int main()
{
Char *D= gettime();
Fprintf(stdout,d);
}

Wat is wrong wth this code… It compiles properly… whr exactly is the problem…
Draw stack for both functions… How n whn stack frame gets overwritten?
What is the problem if we make buf static instead of local..
If it’s a multithreaded , wats the problem?
If u r using mutex whr exactly u wil lock the code?


There is file containing lots of words… ex A Novel . How would find the 25 most occurred words from it…
