In this tutorial, i am going to show you how to check whether the character is alphabet, digit, or special character in c programs.
All C Program to Check Character is Alphabet, Digit or Special Character
- C Program to Check Character is Alphabet, Digit or Special Character using if else
- C Program to Check Character is Alphabet, Digit or Special Character using Ascii value
- C Program to Check Character is Alphabet, Digit or Special Character Function
C Program to Check Character is Alphabet, Digit or Special Character using if else
/* C Program to check Character is Alphabet Digit or Special Character */
#include <stdio.h>
int main()
{
char ch;
printf(" Please Enter any character : ");
scanf("%c", &ch);
if( (ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z') )
{
printf("\n %c is an Alphabet", ch);
}
else if (ch >= '0' && ch <= '9')
{
printf("\n %c is a Digit", ch);
}
else
printf("\n %c is a Special Character", ch);
return 0;
}
The result above c program; as follows:
Please Enter any character : 5 5 is a Digit
C Program to Check Character is Alphabet, Digit or Special Character using Ascii value
#include <stdio.h>
int main()
{
char ch;
printf(" Please Enter any character : ");
scanf("%c", &ch);
if (ch >= 48 && ch <= 57)
{
printf("\n %c is a Digit", ch);
}
else if ( (ch >= 65 && ch <= 90) || (ch >= 97 && ch <= 122) )
{
printf("\n %c is an Alphabet", ch);
}
else
printf("\n %c is a Special Character", ch);
return 0;
}
The result above c program; as follows:
Please Enter any character : $ $ is a Special Character
C Program to Check Character is Alphabet, Digit or Special Character using Function
/* C Program to check Character is Alphabet Digit or Special Character */
#include <stdio.h>
#include<ctype.h>
int main()
{
char ch;
printf(" Please Enter any character : ");
scanf("%c", &ch);
if (isalpha(ch))
{
printf("\n %c is an Alphabet", ch);
}
else if (isdigit(ch))
{
printf("\n %c is a Digit", ch);
}
else
printf("\n %c is a Special Character", ch);
return 0;
}
The result above c program; as follows:
Please Enter any character : w w is an Alphabet
