Replied to thread : How to Efficiently Sort a Large Array of Structs in C?

For efficient sorting of a large array of structs in C, use the qsort function from the standard library along with a custom comparison function tailored to your struct's sorting criteria. Example:

#include <stdio.h>

#include <stdlib.h>


struct MyStruct {

    int id;

    // other fields...



int compareStructs(const void *a, const void *b) {

    return ((struct MyStruct*)a)->id - ((struct MyStruct*)b)->id;



int main() {

    struct MyStruct myArray[1000]; // adjust size as needed


    // initialize array...


    size_t arraySize = sizeof(myArray) / sizeof(myArray[0]);

    qsort(myArray, arraySize, sizeof(myArray[0]), compareStructs);


    // further processing...


    return 0;


This example uses the
qsort function provided by the C standard library. The compareStructs function is a comparison function that compares elements of your struct based on a specific field (id in this case). You can modify the comparison function based on the field you want to use for sorting.
