Check if the String Numeric or Alphabetic

Code

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

void classify_string(const char *str) {
    
    uint8_t isNumaric    = 0;
    uint8_t isAlphabatic = 0;
    uint8_t isMixed      = 0;
    uint8_t isSymbol     = 0;

    for(int i=0; str[i]!='\0'; i++)
    {
        if(str[i]>='0' && str[i]<='9')
        {
            isNumaric =1;
        }

        else if(str[i]>='a' && str[i]<='z')
        {
            isAlphabatic =1;
        }

        
        else if(str[i]>='A' && str[i]<='Z')
        {
            isAlphabatic =1;
        }

        {
            isSymbol = 1;
        }
    }

    if((isAlphabatic && isNumaric) || isSymbol)
    {
        printf("MIXED");
    }

    else if(isAlphabatic)
    {
        printf("ALPHABETIC");
    }


    else if(isNumaric)
    {
        printf("NUMERIC");
    }

}

int main() {
    char str[101];
    fgets(str, sizeof(str), stdin);

    // Remove newline
    uint8_t i = 0;
    while (str[i]) {
        if (str[i] == '\n') {

            break;
        }
        i++;
