How do I add an else statement that'll work with both if statements?

Question

If the user input is "yes" then the code doesn't work well, The Output Becomes:
Then move to the Right, Dummy. :*Please Enter the Correct Data.

#include <stdio.h>
#include <stdlib.h>

//Playing a Game of Checkers..
int main()
{
char user_input[4];
printf("Are you Smart? [yes or no]\n");
scanf("%3s", user_input);
if (strcmp ("yes", user_input) == 0)
{
printf("Then Go left smarty-pants :*");
}
if (strcmp ("no", user_input) == 0)
{
printf("Then play to the Right dummy");
}
else
{
printf("Please Enter the Correct Data");
}
return (0);
}

See how you have 2 if-statements and 1 else statement?

Make it: if-statement, else-if-statement, else-statement. (literally just add the word "else" before the second if-statement)

The second if-statement in your code has an else statement directly below it. And that else statement only applies to the 2nd if-statement.

It prints the extra message when "yes" is entered because the first if statement has no else statement to challenge it. Each if-statement can only have one else-statement, but as many else-if-statements that it needs in between.
