C Program to Sort N Names in Alphabetical Order

Problem:

Write a C program to sort n names/strings in alphabetical order. Write a program that accepts n names/words and displays them in alphabetical or ascending order.

Solution:

In this program we are going to use standard library function strcmp() to compare strings and to sort them in alphabetical order.

Sort n names alphabetically in C:

C program to sort names in alphabetical order

/* Aim: Write a C program to sort names in alphabetical order.*/

#include<stdio.h>
#include<string.h>
#define size 100

void alphabetical_order(int n); // alphabetical_order() Function Prototype

int main()
{
 int n;
 
 printf("\n How many names/strings do you want to sort:- ");
 scanf("%d",&n);

 printf("\n"); 

 alphabetical_order(n);
 printf("\n");

} // End of main

// alphabetical_order() function

void alphabetical_order(int n)
{
	char list[n][20],temp[20];
	int i,j;

	for(i=0;i<n;i++)
	scanf("%s",list[i]); 
 
	for(i=0;i<n-1;i++)
		for(j=i+1;j<n;j++)
		{
			if(strcmp(list[i],list[j])>0)
			{
			strcpy(temp,list[i]);
			strcpy(list[i],list[j]);
			strcpy(list[j],temp);
			}
		}

	printf("\n Names in sorted alphabetical order:- ");

	for(i=0;i<n;++i)
	printf("\n %s",list[i]);
 
} // End of alphabetical_order() Function

/* Output of above code:-
