Search:

temp=pivot;
pivot=a[j];
a[j]=temp;

if changed to



temp=a[low];
a[low]=a[j];

Sorry for the indentation this is the best I could manage , about the main() this is the way I do and I don't think it comes in the way of the program . I have tried tracing the program but the...

This program is supposed to impelement quicksort but it is not working

ok , if that happens "c" and "d" won't be executed as the block following if will be skipped.

Given below is a function which is part of a bigger program implementing Merge Sort http://linux.wku.edu/~lamonml/algor/sort/merge.html


void merge_sort(int a[], int low , int high) //a

Can it be because I'm using float and not double and beacuse the time elapsed is small enough that it doesnt fit onto the float format?

I'm supposed to do a sequential earch on integers and also retun the time elapsed on doing such a search . Here is what I have.

An integer(default in type) type occupies the whole word length of a computer as it's storage . Hence , for a 16 bit computer(my case) one integer occupies 16 bits or convinently 2 bytes. For an...

Yes there is ...we are required to implement queues using array here ...I know this would increase the code length as using link list to implement the same problem is rather easy ....but this is the...

ok will keep it in mind, still the problem though remains unresolved

Sorry but this is the smallest main function I could manage...May be it can be further decomposed into smaller functions but being an absolute rookie in C (my experience with C is as of today 15 days...

My apologies ....when I said I'm posting the "reformed" code i"d posted infact a code that was still half done ......
This is the code which I'd written after the advice .....

heh ok

But 'sum' I thought is of type float and the whole expression is
real expression and hence the right hand side of the assignment operator sum=sum+(1/deno) should be of type float ,isnt it ?

I"m beginning to learn C .The book I follow tells that when any variable has been declared as type int , in 32 bit computer the maximum integer that can be stored is 2147483647 while on 16
