What is null character and what is its use in context of string?
null character exists at the end of the string.It denotes the end of it.
A character array terminated with the null character is most correctly called what?
zero-terminated string
What is the difference between null pointer ASCII null character and null string?
A null pointer is a pointer which does not point to any valid memory location, and usually contains the binary value "0" to represent this (this is language dependent). The ASCII null character is a character-sized zero value (in ASCII, it is an unsigned byte with a value of 0), and typically represents the end of a string (esp. as in C and C++). A null string is one that is zero characters of usable string data; in a length-based string, this means the length parameter is set to 0, and in an ASCII null-terminated string, means the first character is set to 0.
What is java string?
array of character data type which is terminated by null character
Why ÿ occurs at end of string in C?
In C, the character ÿ (which has the ASCII value of 255) can appear at the end of a string if the string is not properly null-terminated. In C, strings are represented as arrays of characters, and they must end with a null character ('\0') to indicate the end of the string. If a string is unintentionally filled with values up to the limit of the array without a null terminator, it might include ÿ as a leftover value from memory. This can lead to undefined behavior when manipulating the string, as functions expect the null character to determine where the string ends.
Why do you need a terminating null character at the end of the every string in C programming?
Because the null character represents the end of the string.

How do you initialize variable?
initialize simple types: int i = 0; initialize objects: Object o = null; (in java)
What ConsoleWriteLine do when NULL character within a string?
it will print nothing on commandline..
Why strcat(string'!') not work in C program?
The strcat() function has the following protocol:char* strcat (char* destination, char* source);The function appends the source string to the destination string and returns the destination string.The destination string must be a null-terminated character array of sufficient length to accommodate strlen (source) plus strlen (destination) characters, plus a null-terminator. The existing null-terminator and subsequent characters of destination are overwritten by characters from the source string, up to and including the source string's null-terminator.strcat (string, '!') will not work because '!' is a character literal (ASCII code 33 decimal), not a null-terminated character array. Use "!" instead of '!'.Example:char string[80]; // character arraystrcpy (string, "Hello world");strcat (string, "!");puts (string);
What symbol or character determines end of string?
In C programming language, a string is an array of characters which is always terminated by a NULL character: '\0'
How can i check a null at the end of an character array in java?
A character array, by nature, is a primitive-type data array. It can't contain a null value. You cannot cast a char as a null. char[] charArray = {'1','2','s',null}; //this doesn't compile. However, if you have an array of Character objects, then it's possible. Character[] charArray = {'1','2','s',null}; //this DOES compile A proposed algorithm is to initialize a test boolean as false, then use a for loop to iterate through the array. Set the flag to true (and break the loop) based upon whether one of the objects you run into is null. What you do from there is up to what the rest of your code says.
What is null string?
main(){ char str[5]="hello"; if(str==NULL) printf("string null"); else printf("string not null"); }
