How to enter a character array in C

There are many ways to enter a character array in C:

cin.getline()

• Syntax: cin.getline(array_name, size, delimiter);

• Parameters:

  • array_name: The name of the character array
  • size: The size of the character array
  • delimiter : Enter the terminating character (such as newline character)

For example:

<code class="cpp">char str[100];
cin.getline(str, 100, '\n');</code>

cin.get( )

• Syntax: cin.get(array_name[index]);

• Parameters :

  • array_name[index]: The index position of the character array

For example:

<code class="cpp">char str[100];
for (int i = 0; i < 100; i++) {
  cin.get(str[i]);
  if (str[i] == '\n') break;
}</code>

gets()

• Syntax: gets(array_name);

• Parameters:

  • array_name: The name of the character array

Note: gets() function is unsafe because if the input is too long, it will cause buffer overflow.

fgets()

• Syntax: fgets(array_name, size, stream);

• Parameters:

  • array_name: The name of the character array
  • size: Characters The size of the array
  • stream: Input stream

##For example:

<code class="cpp">char str[100];
fgets(str, 100, stdin);</code>
