I was programming for my MAZE SOLVING ROBO. and i came across replacing a character, already present, in an array by null value.. what constant shall i use, 0 OR "\n" OR something else ?? another question is that, if i declare an array as : "char a[100] = 0;" What value is currently available in …

What does any element of an array contains, when the array is defined.
