#include <stdio.h>
#include <stdlib.h>

int main()
{
	//create an array of names
	char names[100][30];
	int totalStudents=0;
	int i,j;
	char temp[30];


	printf("Enter the number of students: ");
	scanf("%d",&totalStudents);
	fflush(stdin);
	//Inputting names
	for(int i=0; i<totalStudents; i++){
		printf("Enter the name of student %d: ", (i+1));
		gets(names[i]);
	}


	//Sort array using the Buuble Sort algorithm
	for(i=0; i<totalStudents; i++){
		for(j=0; j<totalStudents-1-i; j++){
			if(strcmp(names[j], names[j+1]) > 0){
				//swap array[j] and array[j+1]
				strcpy(temp, names[j]);
				strcpy(names[j], names[j+1]);
				strcpy(names[j+1], temp);
			}
		}
	}


	//display the sorted array
	printf("Sorted students names:\n");
	for(int i=0; i<totalStudents; i++){
		printf("%s\n", names[i]);
	}


	getchar();
	return 0;
