scanf does not stop at a loop

int main(){
char texto[1000];
do{ 
    scanf("%[^\n]", texto);
    if(!fakeEquals(texto)){
        if(palindromo(texto)){
            printf("SIM\n");
        }else{
            printf("NAO\n");
        }
    }
}while(!fakeEquals(texto));

return 0;

It is a program that returns if a String is palindrome or not, when it was used scan("%s", text); it was working, but since I need to read spaces too, I changed to scanf("%[ n], text); only when I type any word it is returning YES or NOT infinitely...

Just put a space in the scanf(" %[^\n]", texto); because you need to clean the buffer before reading again, otherwise it reads once and then never reads the other word again
