You can have an array of integers or an array of strings or an array of arrays, but you can’t have an array that contains, for example, both strings and integers.
Store things in that array..
What is a constant string?
String constants, also known as string literals, are a special type of constants which store fixed sequences of characters. A string literal is a sequence of any number of characters surrounded by double quotes: “This is a string.” … A null string is stored as a single null character.
How do I turn a char array into a string?

Another plausible way of converting a char array to String is using StringBuilder in Java. … toString() + substring() + Regex. (Not recommended)
How do you turn an array into a string?
Using StringBufferCreate an empty String Buffer object.Traverse through the elements of the String array using loop.In the loop, append each element of the array to the StringBuffer object using the append() method.Finally convert the StringBuffer object to string using the toString() method.
What is string used for?
String is used to tie, bind, or hang other objects. It is also used as a material to make things, such as textiles, and in arts and crafts. String is a simple tool, and its use by humans is known to have been developed tens of thousands of years ago.
What is the difference between a character array and a string in C?
Character Arrays String refers to a sequence of characters represented as a single data type. Character Array is a sequential collection of data type char. Strings are immutable. Character Arrays are mutable.
What is difference between Array and String?
Strings are similar to arrays with just a few differences. Usually, the array size is fixed, while strings can have a variable number of elements. Arrays can contain any data type (char short int even other arrays) while strings are usually ASCII characters terminated with a NULL (0) character.
What is the difference between a character and a string?
Char is a single alphabet where as String is a sequence of characters. Char is primitive datatype where as String is a class. A char holds a single character, while a string holds lots of characters.

What is the data type of string?
A string is generally considered a data type and is often implemented as an array data structure of bytes (or words) that stores a sequence of elements, typically characters, using some character encoding.
Is a string a char array in C++?
Neither C or C++ have a default built-in string type. C-strings are simply implemented as a char array which is terminated by a null character (aka 0 ). This last part of the definition is important: all C-strings are char arrays, but not all char arrays are c-strings.
What is string and its function?
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both). … The most basic example of a string function is the length(string) function. This function returns the length of a string literal.
Why is character array better than string?
Strings are immutable and there is no way that the content of Strings can be changed because any change will produce new String. With an array, the data can be wiped explicitly data after its work is complete. … So Storing password in character array clearly mitigates security risk of stealing password.
Is String a char array?
char is a primitive data type whereas String is a class in java. char represents a single character whereas String can have zero or more characters. So String is an array of chars. We define char in java program using single quote (‘) whereas we can define String in Java using double quotes (“).
What is Array and example?
An array is a data structure that contains a group of elements. Typically these elements are all of the same data type, such as an integer or string. … For example, a search engine may use an array to store Web pages found in a search performed by the user.

The term “string” can be used to represent an arbitrary sequence of items. … As far back as 1888, compositors assembling text for printing used “string” to represent a long string of characters.
What string means?
A string is a data type used in programming, such as an integer and floating point unit, but is used to represent text rather than numbers. It is comprised of a set of characters that can also contain spaces and numbers. For example, the word “hamburger” and the phrase “I ate 3 hamburgers” are both strings.
What is a character array?
A character array is a sequence of characters, just as a numeric array is a sequence of numbers. A typical use is to store a short piece of text as a row of characters in a character vector.
What is the role of string class over character array?
Elements in Character Array are stored contiguously in increasing memory locations which is known as Heap. A String can be converted into Character Array by using the toCharArray() method of String class. On the other hand, a Character Array can be converted into String by passing it into a String Constructor.
