Remove Duplicate Characters from a String

Code

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

void remove_duplicates(char *str) {
    int count = 0; 
    char* selector = str;
    str++;
    
    while(*selector != '\0'){
        
        while(*str != '\0'){
            if(*selector == *str){
                *str = *(str + 1);
                count++;
            }
            str++;
            
            if(count > 1){
              *str = *(str + 1);
              str = selector + 1;
              count = 0; 
            }
        }
        
        selector++;
        str = selector + 1;
        
        count = 0; 
    } 
   

}

   

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

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

    remove_duplicates(str);
    printf("%s", str);
    return 0;
}
