Count Alphabets Digits and Symbols in a String

Code

#include <stdio.h>
#include <stdint.h>

void classify_chars(const char *str, uint8_t *alpha, uint8_t *digit, uint8_t *symbol) {
    // Your logic here
     int a=0,b=0,c=0;
    for(int i=0;str[i]!='\0';i++)

    fgets(str, sizeof(str), stdin);

    // Remove newline
