C Strings

A string is used to store a word or a sentence. This string concept can be obtained through an array of characters. The last character of a string should be a null character. Null character is '10'. String has no separate data type.

We should always enclose the string in double quotes.

String declaration

A string variable can be declared using a character array.

Syntax:

char variable name[size];

EX:

char name[20];

Here name is a string variable. Up to 20 characters can be given inside this name variable.

Initializing String

char program [4]="java"; \\ If you give it like this, an error will appear.

char program [5]="java"; This is the correct method.

Four characters can be stored in the variable called program[4].

There are four characters in java. So, the word java can be stored in a string variable called program[4].

But there is one thing to note here. string always has no place to store null character.

A memory is required to store the null character, so program[4]="java"; It is wrong to give that. The correct method is to give program[5]="java".

Way 2:

char program[]="java";

So the compiler takes the memory size of 4 characters and null character in the variable called program[] in the word java.

Here, the variable called program[] is not given size. Can also be given through character.
