#include <stdio.h> #include <string.h> int main() { int i, j, num; char name[20][10], t_name[15][10], temp[20]; printf("Please enter how many number of names to be sorted in alphabetical order\n"); scanf("%d", &num); printf("Please enter %d names one by one\n", num); for(i=0; i< num ; i++) { scanf("%s",name[i]); strcpy (t_name[i], name[i]); } for(i=0; i < num-1 ; i++) { for(j=i+1; j< num; j++) { if(strcmp(name[i],name[j]) > 0) { strcpy(temp,name[i]); strcpy(name[i],name[j]); strcpy(name[j],temp); } } } printf("Names before sorting in alphabetical order\n"); for(i=0; i< num ; i++) { printf("%s\n",t_name[i]); } printf("Names after sorting in alphabetical order\n"); for(i=0; i< num ; i++) { printf("%s\n",name[i]); } } |
