C Program to Reverse a Sentence Using Recursion

In this tutorial, we will learn to create a C program that will C Program to Reverse a Sentence Using Recursion in C programming.

Prerequisites

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

Operators in C Programming.
Usage of Conditional statements.
Basic Input and Output function in C Programming.
Basic C programming.

Reverse a Sentence Using Recursion

In c programming, we have many predefined functions to workout with. The c language allows us to take long inputs from the users i.e. statements, these string values in the c programming language can be manipulated with the help of many predefined functions available for working.

The string manipulation functions can be applied to the variables or to be exact on the input statements. Available functions in a c programming language can make it easier to work with the strings.

With the help of these functions, we can reverse a string. Change a string to an upper case string or to a lower case string and many more.

Algorithm:-

1. Declaring the variables for the program.

2. Taking the input statement from the user.

3. Send that statement to the function.

4. Passing those variable to if conditional.

5. Printing the result words.

void reverseSentence();
int main() 
{
    //print meaasge to take input sentence
    printf("Enter a sentence: ");
    reverseSentence();
    return 0;
}

void reverseSentence() 
{
    //declaring the vareables 
    char c;
    //Taking Input sentence
    scanf("%c", &c);
    
    if (c != '\n') 
    {
        //printing reverse sentence
        reverseSentence();
        printf("%c", c);

{

//declaring the vareables

char c;

//Taking Input sentence

scanf("%c", &c);

if (c != '\n')

{

//printing reverse sentence

reverseSentence();

printf("%c", c);

}

C Program to Concatenate Two Strings Using Pointers

In this tutorial, we will learn to create a C program that will Concatenate Two Strings Using Pointers in C programming.

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.

While loop in c programming.

Concatenate Two Strings Using Pointers

As we all know the String is a collection of character data types. In strings, only one variable is declared which can store multiple values. First will take the number of elements of string 1 from the user. Then will take the number of elements of string 2 from the user. Then will take the elements from the user for string 1 and as well as for string 2. And concatenate them using the pointer.

With the help of this program, we can Concatenate Two Strings Using Pointers.

Algorithm:-

1. Declaring the variables for the program.

2. Taking the input number from the user.

3. Adding the given sting to pointers.

4. Passing those variables to while loop.

5. Using the those while loop one by one to add the strings.

6. Printing the result words.

}

line[j] = '\0';

}

//printing output

printf("Output String: ");

puts(line);

return 0;

}

Output:-

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

line[150] = it will hold the string value.
i = it will hold the integer value for the loop.

j = it will hold the integer value for the loop.

Taking input string from the user.

Scanning the input string from the user.

Storing the string and extracting only string data by for loop.

C Program to Count the Number of Vowels, Consonants and so on

In this tutorial, we will learn to create a C program that will Count the Number of Vowels, Consonants, and so on in C programming

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.

Count the Number of Vowels, Consonants, and so on

As we all know the String is a collection of character data types. In strings, only one variable is declared which can store multiple values. First will take the line of string from the user. Then will take the number of elements in the string, Now we will filter the string using the c programming.

With the help of this program, we can Count the Number of Vowels, Consonants, and so on.

Algorithm:-

1. Declaring the variables for the program.

2. Taking the input number from the user.

3. Adding the given sting to program  .

4. Passing those variables to forloop.

5. Using those numbers to be saved in variables and filter them with for loop.

6. Printing the result words.

Program to Count the Number of Vowels, Consonants, and so on:-

#include <stdio.h>
int main()
{
    //Declaring the required variables
    char line[150];
    int vowels, consonant, digit, space;
    //Assigning blank value to all
    vowels = consonant = digit = space = 0;
    
    //Taking Input string From the user
    printf("Enter a line of string: ");
    
    fgets(line, sizeof(line), stdin);
    //Getting size of string from the user
    
    for (int i = 0; line[i] != '\0'; ++i) 
    {
        ////filtering vowels from the string
        if (line[i] == 'a' || line[i] == 'e' || line[i] == 'i' ||
            line[i] == 'o' || line[i] == 'u' || line[i] == 'A' ||

        else if (line[i] >= '0' && line[i] <= '9')
        {
            ++digit;
        }
        
        ////filtering white spaces from the string
        else if (line[i] == ' ')
        {
            ++space;
        }
    }

    //Printing number of vowels 
    printf("Vowels: %d", vowels);
    //Printing number of consonants
    printf("\nConsonants: %d", consonant);
    //Printing number of Numbers
    printf("\nNumbers: %d", digit);
    //Printing number of White spaces
    printf("\nWhite spaces: %d", space);
    return 0;
}

#include <stdio.h>

int main()

{

//Declaring the required variables

char line[150];

int vowels, consonant, digit, space;

//Assigning blank value to all

vowels = consonant = digit = space = 0;

//Taking Input string From the user

printf("Enter a line of string: ");

fgets(line, sizeof(line), stdin);

//Getting size of string from the user

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

{

////filtering vowels from the string

if (line[i] == 'a' || line[i] == 'e' || line[i] == 'i' ||

line[i] == 'o' || line[i] == 'u' || line[i] == 'A' ||

line[i] == 'E' || line[i] == 'I' || line[i] == 'O' ||

line[i] == 'U')

{

//filtering consonants from the string

////filtering white spaces from the string

else if (line[i] == ' ')

{

++space;

}

//Printing number of vowels

printf("Vowels: %d", vowels);

//Printing number of consonants

printf("\nConsonants: %d", consonant);

//Printing number of Numbers

printf("\nNumbers: %d", digit);

//Printing number of White spaces

printf("\nWhite spaces: %d", space);

}

Output:-

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

line[150] = it will hold the string value.
vowels = it will hold the integer value for vowels.

consonant = it will hold the integer value for consonants.
digit= it will hold the integer value for numbers.
space= it will hold the integer value for spaces.

Input strings from the user.

Assigning blank value to all to prevent garbage value.
