Remove Duplicate Characters from a String

Code

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

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

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;
}
