Inserting value that includes single quotes

INSERT INTO abc VALUES
(
1,
'Write 'C' Program to add two Number'
);

a number;
b varchar(30);

'write 'C' program',
        *
ERROR at line 4:
ORA-00917: missing comma

Inserting the single quote can be done in two ways.

1) Using extra quotes to insert "C with single quotes around it"

2) To use the function to get the character from its corresponding ASCII value, for single quotes it is 39.

I will provide both examples for you.

1)  INSERT INTO abc VALUES
  ( 1, 'Write "C" Program to add two Number');

2) INSERT INTO abc VALUES
    (1, 'Write ' || CHR(39) || 'C' || CHR(39) || ' Program to add two Number');
