Check special character in C by R4R Team

Special characters:
All Character except the english alphabet and numbers are the special characters.

Example-
! # $ % ^ & * ( ) etc.

How we identify?
-We use te ASCII value concept to identify each and every character of the keyword.

program-

#include < stdio.h>
int main()
{
char ch;
printf("Enter any character\n");
scanf("%c",&ch);
if((ch>='A' && ch<='Z') | (ch>='a' && ch<='z') | (ch>='0' && ch<='9'))
{
printf("It is not a special character");
}
else
{
printf("It is a special character");
}
return 0;
}

output-

Enter any character
A
It is not a special character

Enter any character
3
It is not a special character

Enter any character
$
It is a special character

-In this program, we take a input of the any character,and check whether it is special character or not.
-We check that character is alphabet,numbers or not.
-If input character is not the alphabet or not the number then it will execute the else part which will implies as special character were input.
