I did not understand that if the size of the buf variable is 3 then after getting input "y" and "\n" how does stdin terminate the coming input i.e. what would be buf[2]??

char buf[3];...

I would like to know the exact difference between calloc and which is more useful?? Though calloc allocates memory in the form of blocks and malloc in a single block , do they both allocate memory...

Thanks for the reply :)

I would like to know what is the difference betn
getchar(),getch(), and getche() functions and which should be used in which conditions.
Thanks,

Even if we evaluate from the right for j=1 the expression will be evaluated like 1 + 3 + 3 and will still turn out to be 7. Do you mean that theres no conventional way of how to evaluate this...

I am having this problem with precedence of operators. Its with the increment and decrement operators.

int i,j=1;
i=(j++)+(++j)+(j++);

this evaluates to 6 instead of 7 . Why does this happen....

Heres a precise and short way to permute any word without pointers

I want to run this program in C where I can compute 2^(3.5).Is this possible in C?

Hi everyone,
I am having this problem to define a function which raises a float y eg 3.5 which is not a whole number to the base x.
Heres the code which gives domain error as function pow takes...
