Answer 1

#include <stdio.h> #include <stdlib.h> #include <string.h> static int myCompareString(const void* s, const void* g) {     return strcmp(*(const char**)s, *(const char**)g); } void sort(const char* a[], int n) {     // calling qsort function to sort the array     // with the help of Comparator     qsort(a, n, sizeof(const char*),myCompareString); }    int main() {     const char* a[]         = { "hello ", "everyone", "there" };        int n = sizeof(a) / sizeof(a[0]);     int i;        // Printing the given names     printf("Given array is\n");     for (i = 0; i < n; i++)         printf("%d: %s \n", i, a[i]);        // Sorting the given names     sort(a, n);        // Printing the sorted names     printf("\nSorted array is\n");     for (i = 0; i < n; i++)         printf("%d: %s \n", i, a[i]);        return 0; }
