As I know in C++ you can change the value of (char *) variable , but I have an error.

This is a screenshot.

The error is:

error C2440: '=': cannot convert from 'const char [71]' to 'char *'

before I declared a char* variable:

char *sql;

and then I want to use it, but:

sql = "INSERT INTO person (id,name,last,age) "  \
    "VALUES (1, 'Paul', 'Yezh', 14); ";

On the equal sign I have this error.

Since character strings are constant arrays, you need to change the type of sql to const char *sql.

Or copy the string if it needs to be modified.

This answer is correct. Consider also that all compiler errors are well documented online. See here for a clear and easy explanation of the C2440 error. Always check documentation.
