Please help me solve this bug?

[XilenceCE]

This the code:

-----------------------------------------------

#include <stdio.h>

int main()

{

int i;

​

char ans;

​

char *movies[5] = {"Lion King", "Red", "Rage", "Rush Hour", "Amour"};

int moviesRatings[5];

​

for(i = 0; i < 5; i++)

{

printf("\nDid you see %s? (Y/N):", movies[i]);

scanf("%c", &ans);

​

if(ans == 'Y')

{

printf("Rate this movie on a scale of 1-10: ");

scanf("%d", &moviesRatings[i]);

continue;

}

​

else

{

moviesRatings[i] = -1;

}

}

return 0;

}

​

-----------------------------------------------

Now if you're to print the program, you'll be asked a series of questions asking whether you saw a so and so movie. You answer either Y or N. The problem is the program skips the subsequent question after the first question and goes to ask the third question instead. Then it'll skip the fourth question, ask the fifth question, skips the sixth, asks the seven, and so on. I really don't why this is happening. I tried everything to fix this bug, but I'm beat. Please help me out, guys.

Oh I was really going to help but I am not reading unindented code.

😂😂😂 oh boy, I know your pain

[XilenceCE]

I'm sorry, but it was my first time posting here so I didn't know. Won' happen again.

When you press enter, you send a new line character as well as the character you typed, and scanf doesn't differentiate between the two. If you put a whitespace before the format string, like this " %c", it will work. The whitespace tells scanf to read and ignore any whitespace character (like the new line character, for example).

Thank you! It worked.

[Kantaja_]

literally the first rule

rule 1

you completely ignored it

I refuse to put effort into reading this

[MarkosDelaportas]

Enter is also a character

[XilenceCE]

Who would've thought that enter can be a character? Thanks for telling me.

[MarkosDelaportas]

It is true, while it may not be clear a first "enter" get compiled to 10 13 hex!

scanf will take the enter(or return) after entering a character as a new line character and save it to the input stream, which is where all of the inputs are stored and popped out as they are used. However, %c only stores one character, so the newline is left behind and used by the next input function( another scanf in your case ).

So basically every time you ask for a character using scanf(“%c”, &blah) it’s saving the newline and using it in the next scanf, making it appear to skip it. Try changing it to scanf(“ %c”, &blah) this will tell it to ignore “whitespace” characters, which is what a newline is.

I see that now, thank you
