Remove Duplicate Characters from a String

Code

#include <stdio.h>
#include <stdint.h>
#include<string.h>
void remove_duplicates(char *str) {
	//Your logic here

    int i=0,j=0;
    for(i=0;str[i];i++)
    {
        for(j=i+1;str[j];j++)
        {
            if(str[i] == str[j])
            {
                memmove(&str[j],&str[j+1],strlen(&str[j])+1);
            }
        }
    }
    }

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;
}
