C-program to check that given character is an alphabet, digit or special character

Here in this post we will write a program to check the given character is alphabet or digits or a special character. So for this we will use ASCII value  as we know the ascii of A-Z is 65-90 and a-z is 97-122 , The ascii of 0-9 is 48-57 and except these all are the special characters. So here is the program to check that the given character is alphabet , digits or a special character.

C-program to check that the given character is alphabet , digit or a special character

Code:-

#include<stdio.h>

int main()

{

char n;

printf("Enter any character:");

scanf("%c",&n);

if((n>=65 && n<= 90) || (n>=97 && n<=122))

printf("This is an Alphabet");

else if(n>=48 && n<=57)

printf("This is a Number");

else

printf("This is a special character");

return 0;

}

Output:-

Enter any character: 9

This is a Number
