How to check character is vowel or consonant in C language( Else if ladder or multiple else if )

Introduction: 

In this article I will explain how to check the character you entered is Vowel or Consonant using If-else Ladder in C.

A,E,I,O,U is known as Vowel and other alphabets are called Consonants.

#include<conio.h>

#include<stdio.h>

main()

{

       char ch;

      printf("Enter  any character between a to z : ");

      scanf("  %c",&ch);

                      if(ch=='a')

                            {

                            printf("%c  is vowel”,ch);

                            }

                      else if(ch=='e')

                            {

                            printf("%c  is vowel”,ch);

                            }

                      else if(ch=='i')

                            {

                            printf("%c  is vowel”,ch);

                            }

                      else if(ch=='o')

                            {

                            printf("%c  is vowel”,ch);

                            }

                        else if(ch=='u')

                            {

                            printf("%c  is vowel”,ch);

                            }                                

                    else

                           {

                            printf("%c  is consonant”,ch);

                           }

                    getch();

                    }

                   

 Run the program using Ctrl+F9

                   

Output:

First Run

 Enter any character between a to z : u

 u is vowel 

Second Run

 Enter any number between a to z : p

 p is consonant

Swap two numbers in C Language ?

Introduction: 

This is very common question asked by Interviewer to fresher to check their basics.

 In this article I will explain swapping using a temporary variable or third variable.

Program example: Let's understand by an program

#include<stdio.h>

#include<conio.h>

void main()

{

 int a,b,temp;

  clrscr();

 printf("Enter the value of a= ");

 scanf("%d",&a);

 printf("\nEnter the value of b= ");

 scanf("%d",&b);

 printf("\nValue of a before swapping= %d",a);

 printf("\nValue of b before swapping= %d",b);

 temp=a;

 a=b;

 b=temp;

 printf("\nValue of a after swapping= %d",a);

 printf("\nValue of b after swapping= %d",b);

 getch();

 }

Run the program using ctrl+F9

Output:

Enter the value of a=11

Enter the value of b=22

Value of a before swapping=11

Value of b before swapping=22

Value of a after swapping=22

Value of b after swapping=11
