What is String

String:

1. String is a collection of two or more characters.
2. In string we can store alphabets digits and special symbols.
3. when we declare array of character type then it is called as string.
4. In C, character type array is used to store a string.

Declaration of String:

The declaration of string is similar like Array.
for declaring string we need to specify its size means maximum of how many characters we have to store in string.

Syntax: char string[size];

Example: char str[20];

Here we declare a string variable str of size 20 means variable 'str' characters.

Initialization of String:

while declaring string we can also initialize some value at the time of declaration.

Syntax: char string[size]="text";

Example: char str[20]="programmingsolution";

Here we declare a string variable 'str' of size 20 and assign programmingsolution to it.

Inputting string:

To input the content in the string two function used as 'scanf()' and 'gets()'.
In 'scanf()' function spaces are not allowed in a string.if we give space then the remaining part will be truncated from string.
In 'gets()' function spaces are allowed in a string.

Syntax:    scanf("%s",string_variable);

                 gets(string_variable);

Example: scanf("%s",str);

                 gets(str);
