Remove Duplicate Characters from a String

Code

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

void remove_duplicates(char *str) {
	//Your logic here
    int length = 0 ;
    while (str[length] != '\0') {
        int temp = length + 1;
        while (str[temp] != '\0') {
            if (str[temp] == str[length]) {
                for (int i = temp; str[i] != '\0'; i++) {
                str[i] = str[i + 1];
                }
            }
            temp++;
        }
        length++;
    }
    }

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;
}
