Program 31:To know whether the character is vowel or not

Program 31:
 

#include<stdio.h>
main()
{
  char c;
  printf("Enter a character to know whether it is vowel or not\n");
  scanf("%c",&c);
  if(c=='A'||c=='a'||c=='e'||c=='E'||c=='I'||c=='i'||c=='O'||c=='o'||c=='U'||c=='u')
    printf("The character %c is vowel\n",c);
  else
    printf("The character %c is not vowel\n",c);
}

Explanation:

1. The program starts with initializing :
   • c → To store Input character

2. printf("Enter a character to know whether it is vowel or not\n");
   scanf("%c",&c);

   Taking input from user.If the input is A(say)

3. if(c=='A'||c=='a'||c=='e'||c=='E'||c=='I'||c=='i'||c=='O'||c=='o'||c=='U'||c=='u')
   printf("The character %c is vowel\n",c);
   else
   printf("The character %c is not vowel\n",c);

   This is the main logic of the program.The input given by user is verified with all the conditions in if part.
4. As we have given A as input then it will check with A,a,e,E,...u,U.And if any one of the character is equal to input then it is vowel else not

Output:
