Remove Duplicate Characters from a String

Code

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

void remove_duplicates(char *str) {
	//Your logic here
    int i,j,k=0;
    for(i=0;str[i];i++)
    {
        for(j=0;j<i;j++)
        {
            if(str[i]==str[j])
            {
                 break;
            }           
        }
        if(i==j)
        {
            str[k++]=str[i];
        }
    }
    str[k]='\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;
}
