C Program To Check Whether A Character Is A Vowel Or Consonant Using If-else

In this tutorial, you will learn to write a program to check whether a character is a vowel or constant using if-else. Here, we are using examples, and algorithms with fully explained programs for your better understanding of this problem. This topic is also suited for checking whether an input character is a vowel or consonant in the C program using if-else.Problem StatementWe have to Write a C program that checks whether a given character is a vowel or a consonant. Our program should take a character as input and after checking they should spring a character as a vowel or consonant.ExampleEnter a character: AOutput: The character A is a vowel.Enter a character: ZOutput: The character Z is a consonant.Algorithm to Check Character Is A Vowel Or Consonant Using If-else- Start the program.- Declare a variable character of type char to store the input character.- Prompt the user to enter a character by printing the message "Enter a character: ".- Read the input character from the user and store it in the character variable using scanf().- Convert the character to uppercase using the toupper() function to handle lowercase inputs.- Use an if-else statement to check if the input character is a vowel or a consonant:- If character is equal to 'A', 'E', 'I', 'O', or 'U', print the message "The character is a vowel."- Otherwise, print the message "The character is a consonant."- End the program.C Program to check whether a character is a vowel or consonant #include #include int main() { char character; printf("Enter a character: "); scanf(" %c", &character); character = toupper(character); if (character == 'A' || character == 'E' || character == 'I' || character == 'O' || character == 'U') { printf("The character %c is a vowel.n", character); } else { printf("The character %c is a consonant.n", character); } return 0;}Output 1Enter a character: AThe character A is a vowelOutput 2Enter a character: SThe character S is a consonantProgram Explanation- The program starts by including the necessary header files: stdio.h for input/output functions and ctype.h for character handling functions.- The main() the function is defined.- Inside the main() function, a variable character of type char is declared to store the input character.- The program prompts the user to enter a character by printing the message "Enter a character: ".- The scanf() function is used to read a character from the user, and the input is stored in the character variable using the %c format specifier. A space is added before %c in scanf to consume any leading whitespace or newline characters from the previous input.- The toupper() function is used to convert the input character to uppercase to handle lowercase inputs.- An if-else statement is used to check if the input character is a vowel or a consonant:- If the input character is 'A', 'E', 'I', 'O', or 'U', the program prints the message "The character is a vowel." The %c format specifier is used in printf() to print the character.- If the input character is not one of the vowels, the program prints the message "The character is a consonant."- The return 0 statement ends the program.ConclusionThis C program allows the user to enter a character and determines whether it is a vowel or a consonant using if-else statements. It covers all possible cases and provides the appropriate output based on the input character.

C Program To Print Maximum Among Three Numbers Using If-else

IntroductionIn this tutorial, you will learn how to write a C program to print the maximum among three numbers by using if-else statement. We have also explained some examples, algorithm, and programs for your better understanding. Problem StatementWrite a C program that reads three numbers from the user. After taking the inputs it should determine the maximum among them using the "if-else" statement. The program should display the maximum number as output.ExampleEnter the first number: 8Enter the second number: 12Enter the third number: 15The maximum number is 15In the above example 15 is printed as an output means it is a greatest among other (8, 12). So Here the Output will be 15 and it is correct.Algorithm- Start the program.- Read the first number and store it in a variable, let's say num1.- Read the second number and store it in another variable, let's say num2.- Read the third number and store it in a third variable, let's say num3.- Compare num1, num2, and num3 using the "if-else" statement: a. If num1 is greater than both num2 and num3, print num1 as the maximum number. b. If num2 is greater than both num1 and num3, print num2 as the maximum number. c. Otherwise, print num3 as the maximum number.- End the program.Program To Print Maximum Among Three Numbers#include int main() { int num1, num2, num3; printf("Enter the first number: "); scanf("%d", &num1); printf("Enter the second number: "); scanf("%d", &num2); printf("Enter the third number: "); scanf("%d", &num3); if (num1 > num2 && num1 > num3) { printf("The maximum number is %d.n", num1); } else if (num2 > num1 && num2 > num3) { printf("The maximum number is %d.n", num2); } else { printf("The maximum number is %d.n", num3); } return 0;}OutputEnter the first number: 65Enter the second number: 23Enter the third number: 45The maximum number is 65Program Explanation- We start by including the necessary header file stdio.h for input/output operations.- The main() function is the entry point of the program.- We declare three variables num1, num2, and num3 to store the input numbers.- We prompt the user to enter the first number using printf().- The scanf() function is used to read the first number and store it in the variable num1.- We repeat steps 4 and 5 for the second and third numbers.- Using the "if-else" statement, we compare num1, num2, and num3.- If num1 is greater than both num2 and num3, we print num1 as the maximum number.- If num2 is greater than both num1 and num3, we print num2 as the maximum number.- Otherwise, we print num3 as the maximum number.- Finally, the program ends and returns 0 to the operating system.ConclusionIn conclusion, the C program we developed successfully solves the problem of finding the maximum among three numbers using the if-else statement. It allows the user to input three numbers, compares them, and displays the maximum number as the output. The program demonstrates the use of conditional statements and input/output operations in C programming. By understanding this program, you have gained knowledge of how to make decisions based on conditions and perform basic input/output operations in C.
