according to this site http://www.cplusplus.com/reference/clibrary/cstdlib/qsort/ i have done following program which sorts strings #include <cstdlib> #include <stdio.h> #include <stdlib.h> #include <string.h> char list[5][4]={"dat","mai","lik","mar","ana"}; int main(int argc, char *argv[]) { int x; puts("sortirebamde:"); ...
The main view of my application contains a one-level (no children) QTreeView that displays on average 30,000 items. Due to the way the items are created, they are inserted into the model unsorted. This means that on application startup I have to sort the items in the view alphabetically, which takes nearly 1 second, leaving an unresponsi...

Hello, I have a question regarding qsort. This is a little bit weird, but my qsort function does not give me the correct output. The strange thing is that some of my compare functions are identical to my past projects but they don't give me the correct input at all. I am not sure how to test it. For example: int comp_name_asc(const v...
#include<stdio.h> #include<stdlib.h> #define MAX 1000 struct island{ double left; //gobal double right; } island[MAX]; ... int cmp(const void *ptr1,const void *ptr2 ) { return (*(struct island*)ptr1).right > (*(struct island*)ptr2).right; } qsort(island,num,sizeof(island[0]),cm...
I'm doing K&R exercise 6-4, which is: 6-4. Write a program that prints the distinct words in its input sorted into decreasing order of frequency of occurrence. Precede each word by its count. What I decided to do is create a struct called dstncFreqNode6_4: struct dstncFreqNode6_4 { char *word; int count; struct dstncFreqN...
Hi, I'm trying to sort a structure I've created via qSort however it seems to be be doing what I expect it to. This is my compare function int compare(const void *a, const void *b) { const INPUT *p1 = a; const INPUT *p2 = b; return ((p1->startTime) - (p2->startTime)); } Where INPUT is my structure and startTime is an int...
the question is simple: there is some way that the ordered array that returns me the "qsort", is returned in reverse, ie I want to avoid the use of any auxiliary array to invest the resulting array using qsort. this is my code, which reads from standard input strings to be sorted, and uses a comparison function for sorting. #includ...
I am using the built in qsort to sort an array of structs. But after the call to qsort the last element in the array seems to have had its value that I am sorting by set to empty. Here is my code... int numEntries = 5; TvEntry* entries[numEntries]; //create array //Entries get added to the array here... qsort( *entries, numEntries, s...
