C program to find given string has alphabets, digits and special characters in it
there are lots of snippets of C code online. google is your friend.
but i didn't find any solution for it
If you know the ascii code,
48-57 0-9
65-90 A-Z
97-122 a-z
Most of the remainder (0-127) are special characters, except space (32) and perhaps other white space characters.
It will consist of one while loop to check each of the above.

To determine if a given string has alphabets, digits, and special characters, you can write a C program that iterates through each character in the string and checks its type using standard library functions. Here's an example program that demonstrates this:
```c
#include <stdio.h>
#include <ctype.h>
int main() {
char str[100]; // assuming maximum string length is 100
int has_alphabet = 0, has_digit = 0, has_special = 0;
int i;
printf("Enter a string: ");
fgets(str, sizeof(str), stdin);
for (i = 0; str[i] != '\0'; i++) {
if (isalpha(str[i]))
has_alphabet = 1;
else if (isdigit(str[i]))
has_digit = 1;
else if (!isspace(str[i]))
has_special = 1;
}
if (has_alphabet)
printf("The string has alphabets.\n");
else
printf("The string does not have any alphabets.\n");
if (has_digit)
printf("The string has digits.\n");
else
printf("The string does not have any digits.\n");
if (has_special)
printf("The string has special characters.\n");
else
printf("The string does not have any special characters.\n");
return 0;
}
```
In this program, we declare three boolean variables `has_alphabet`, `has_digit`, and `has_special`, initialized to 0. We then use a `for` loop to iterate through each character of the given string.
Inside the loop, we use the `isalpha` function from the `ctype.h` library to check if each character is an alphabet. If so, we set the `has_alphabet` variable to 1.
Next, we use the `isdigit` function to check if the character is a digit. If yes, we set the `has_digit` variable to 1.
Finally, we use the `isspace` function to check if the character is a white space character. If not, and the previous conditions were not met, then we consider the character as a special character and set the `has_special` variable to 1.
After looping through all characters, we use `if-else` statements to print the appropriate messages based on the values of `has_alphabet`, `has_digit`, and `has_special` variables.
Note: The `fgets` function is used to read the string from the user, and it includes the newline character (\n) at the end.
