In this tutorial, we will sort the array in ascending order from the smallest to the biggest value of the array.

Algorithm:-

1. Declaring  the variables for the program. 

2. Taking the input size of the array. 

3. Taking the elements in the array. 

4. Sending that array to the for loop for sorting. 

5. Print the Sorted element of array in ascending order. 

6. End the program.

What is Quick Sort?

In every programming language, the sorting of data is a very important factor. Sorting works are done mainly with the techniques available in C Language. Many different techniques for sorting are available to work with but in this tutorial, we will focus on the Quick Sort Technique.

The Quicksort is a sorting algorithm based on dividing the array and arranging where an array is divided into sub-arrays and the number is taken from the array itself. Then We will sort that array using the quick sort method.

Program For Quick Sort:-

In this program, we will perform the quick-sort algorithm

// C Program to Implement Quick Sort Algorithm

#include <stdio.h>

// function to swap elements
void swap(int *a, int *b) {
  int t = *a;
  *a = *b;
  *b = t;
}

// function to find the partition position
int partition(int array[], int low, int high) {
  
  // select the rightmost element as pivot
  int pivot = array[high];
  
  // pointer for greater element
  int i = (low - 1);

  // traverse each element of the array
  // compare them with the pivot
  for (int j = low; j < high; j++) {
    if (array[j] <= pivot) {
        
      // if element smaller than pivot is found
      // swap it with the greater element pointed by i
      i++;
      
      // swap element at i with element at j
      swap(&array[i], &array[j]);
    }
  }

  // swap the pivot element with the greater element at i
  swap(&array[i + 1], &array[high]);
  
  // return the partition point
  return (i + 1);
}

void quickSort(int array[], int low, int high) {
  if (low < high) {
    
    // find the pivot element such that
    // elements smaller than pivot are on left of pivot
    // elements greater than pivot are on right of pivot
    int pi = partition(array, low, high);
    
    // recursive call on the left of pivot
    quickSort(array, low, pi - 1);
    
    // recursive call on the right of pivot
    quickSort(array, pi + 1, high);
  }
}

// function to print array elements
void printArray(int array[], int size) {
  for (int i = 0; i < size; ++i) {
    printf("%d  ", array[i]);
  }
  printf("\n");
}

// main function
int main() 
{
  //Declaring the reuqired variables for the program
  int arry[] = {8, 7, 2, 1, 0, 9, 6};
  
  int n = sizeof(arry) / sizeof(arry[0]);
  //PRinting the unsorted array
  printf("Unsorted Array\n");
  printArray(arry, n);
  
  // perform quicksort on arry
  quickSort(arry, 0, n - 1);
  //Printing the sorted array
  printf("Sorted array in ascending order: \n");
  printArray(arry, n);
}

// C Program to Implement Quick Sort Algorithm

// select the rightmost element as pivot

int pivot = array[high];

// pointer for greater element

int i = (low - 1);

// traverse each element of the array

// compare them with the pivot

for (int j = low; j < high; j++) {

if (array[j] <= pivot) {

// if element smaller than pivot is found

// swap it with the greater element pointed by i

i++;

// swap element at i with element at j

swap(&array[i], &array[j]);

}

// swap the pivot element with the greater element at i

swap(&array[i + 1], &array[high]);

// return the partition point

return (i + 1);

}

void quickSort(int array[], int low, int high) {

if (low < high) {

// find the pivot element such that

// elements smaller than pivot are on left of pivot

// elements greater than pivot are on right of pivot

int pi = partition(array, low, high);

// recursive call on the left of pivot

}

// function to print array elements

void printArray(int array[], int size) {

for (int i = 0; i < size; ++i) {

printf("%d ", array[i]);

}

printf("\n");

}

// main function

int main()

{

//Declaring the reuqired variables for the program

int arry[] = {8, 7, 2, 1, 0, 9, 6};

int n = sizeof(arry) / sizeof(arry[0]);

//PRinting the unsorted array

printf("Unsorted Array\n");

printArray(arry, n);

// perform quicksort on arry

quickSort(arry, 0, n - 1);

//Printing the sorted array

printf("Sorted array in ascending order: \n");

printArray(arry, n);

}

Output:-

In the above program, we have first declared and initialized a set of variables required in the program.

no = it will hold the size of an array.
x[]= it will hold the elements in an array.
i= it will hold the integer value to the control array.

C Program to Toggle Case of all Characters in a String

In this tutorial, we will learn to create a C program that will Toggle the Case of all Characters in a String in C programming.

Prerequisites.

Before starting with this tutorial, we assume that you are the 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.

What is a String?

The String is a collection character. The character is a single entity in the English language or in any word. These characters can be any alphabets in lower case or upper case.

The lower case means the small letters. And the upper case means the capital letters of the English language.

For Example:-

In the string “Hello”, there are five characters, they are as follows

Here,

‘H’ is a character in the Upper case.

‘e’ is a character in the lower case.

‘l’ is a character in the lowercase.

‘l’ is a character in the lower case.

‘o’ is a character in the lowercase.

Algorithm:-

1. Declaring the variables for the program.

2. Taking the input String from the user.

3. Passing that variable to conditional statements.

4. Using those conditions to toggle the case of the String.

5. Printing the resultant String to the user.

6. End The Program.

int main()
{
        //declaring the required variable for the prorgam.
  	char Str1[100];
  	int i;
 
  	printf("\n Please Enter any String to Toggle : ");
  	gets(Str1);
  	
  	for (i = 0; Str1[i]!='\0'; i++)
  	{
  		if(Str1[i] >= 'a' && Str1[i] <= 'z')
  		{
  			Str1[i] = Str1[i] - 32;
		}		
  		else if(Str1[i] >= 'A' && Str1[i] <= 'Z')
  		{
  			Str1[i] = Str1[i] + 32;
		}
  	}

  	printf("\n The Given String after Toggling Case of all Characters = %s", Str1);
  	
  	return 0;
}

/* C program to Toggle Case of all Characters in a String */

#include <stdio.h>

int main()

{

//declaring the required variable for the prorgam.

char Str1[100];

int i;

printf("\n Please Enter any String to Toggle : ");

gets(Str1);

for (i = 0; Str1[i]!='\0'; i++)

{

if(Str1[i] >= 'a' && Str1[i] <= 'z')

{

Str1[i] = Str1[i] - 32;

}

else if(Str1[i] >= 'A' && Str1[i] <= 'Z')

{

Str1[i] = Str1[i] + 32;

}

printf("\n The Given String after Toggling Case of all Characters = %s", Str1);

return 0;

}
