Extra characters added to end of string in c

Question

So I am trying to print out a string in C and I am consistently getting extra characters at the end of the string when I print it out. The Code:

char binaryN         


        

Answer 1

Let the compiler determine the amount of elements needed

char binaryNumber[] = "1111000011110000";
// same as
// char binaryNumber[17] = "1111000011110000";

Answer 2

It should be

char binaryNumber[17] = "1111000011110000";

This is because strings in C are null terminated. So you will be reading garbage if you don't give an extra character space for the implicit \0 which will be added

Answer 3

You have 16 characters in your array. and there is no place to hold a \0 character.

%s prints a string until it encounters a \0

So what you are seeing is some garbage characters being printed out.Please make your string is \0 terminated
