Code:

int main (void)
{

    char *temp;
    int y=0, counter=0;

    cout << "Enter String: ";

    temp = new char [strlen(str)];                

	*temp = UselessFunction(counter,y, temp, str);

	strcpy(str,temp);                   
	strrev(temp);                        

	if(strcmp(str,temp)==0)
