'If' Statement inside the Switch statement being ignored.
I created a history review program in C language.
In case 10, there are problems with the 2 if statements enclosed.
1. Question 1: The U.S. Constitution prohibits the establishment of a state religion. Regardless of whether I enter TRUE or FALSE, it always displays "Incorrect".
2. Question 2: Identify the name of this specific provision. Regardless of what I enter, it always displays "Incorrect".
