C Program to Sort Names in Alphabetical Order

Prerequisites

Before starting with this tutorial we assume that you are best aware of the following C programming topics:

Operators in C Programming.

Basic Input and Output function in C Programming.
Basic C programming.
For loop in C Programming.

String functions in C programming.
Conditional statement in C Programming.

Sort Names in Alphabetical Order:-

As we all know String is a collection of similar data type elements. In an array, only one variable is declared which can store multiple values. First will take the string input from the user. Then will pass that string to the for loop to sort it in alphabetical order. And at last, we will Sort Names in Alphabetical Order C Programming Language.

Algorithm:-

1. Declaring the variables for the program.

2. Taking the array size from the user.

3. Taking the list of the names.

4. Sorting the list of the names.

5. Printing the results.

6. End program.

Program:-

Sort Names in Alphabetical Order

#include<stdio.h>
#include<string.h>
int main()

{
    //declaring the variable for the the program
   int i,j,n;
   char str[100][100],s[100];
   //Taking input number of names
   printf("Enter number of names :\n");
   scanf("%d",&n);
   //Taking the names in input
   printf("Enter names in any order:\n");
   for(i=0;i<n;i++){
      scanf("%s",str[i]);
   }
   //Comparing the string and sorting the string
   for(i=0;i<n;i++){
      for(j=i+1;j<n;j++){
         if(strcmp(str[i],str[j])>0){
            strcpy(s,str[i]);
            strcpy(str[i],str[j]);
            strcpy(str[j],s);
         }
      }
   }
   //Printing the sorted names
   printf("\nThe sorted order of names are:\n");
   for(i=0;i<n;i++){
      printf("%s\n",str[i]);
   }
return 0;
    
}

#include<stdio.h>

#include<string.h>

int main()

{

//declaring the variable for the the program

int i,j,n;

char str[100][100],s[100];

//Taking input number of names

printf("Enter number of names :\n");

scanf("%d",&n);

//Taking the names in input

printf("Enter names in any order:\n");

for(i=0;i<n;i++){

scanf("%s",str[i]);

}

//Comparing the string and sorting the string

for(i=0;i<n;i++){

for(j=i+1;j<n;j++){

if(strcmp(str[i],str[j])>0){

strcpy(s,str[i]);

strcpy(str[i],str[j]);

strcpy(str[j],s);

}

//Printing the sorted names

printf("\nThe sorted order of names are:\n");

for(i=0;i<n;i++){

printf("%s\n",str[i]);

}

return 0;

}

Output:-

In the above program, we have first initialized the required variable

s[100] = it will hold the elements in a string.
str[100][100] = it will hold the string value.
i = it will hold the integer value to control the array.

j = it will hold the integer value to control the array.
n = it will hold the integer value to control the array.

Taking input string from the user.

Sorting the string in alphabetical order.

Printing the results.
