Operator &= (Concatenate And Assign)
Appends and assigns a string onto another string
Declare Operator &= ( ByRef lhs As String, ByRef rhs As T2 )
Declare Operator &= ( ByRef lhs As WString, ByRef rhs As T2 )
lhs &= rhs
lhs
This operator appends one string onto another. The right-hand side expression (rhs) is converted to a string before concatenation. It is functionally equivalent to,
where the result is assigned back to the left-hand side string.
This operator can be overloaded for user-defined types.
Note: This operator exists in C/C++ with a different meaning - there it performs a bitwise And=.
will produce the output:
Syntax
Declare Operator &= ( ByRef lhs As String, ByRef rhs As T2 )
Declare Operator &= ( ByRef lhs As WString, ByRef rhs As T2 )
Usage
lhs &= rhs
Parameters
lhs
The string to assign to.
rhsThe value to append to lhs.
T2Any numeric, string or user-defined type that can be converted to a string.
Description
This operator appends one string onto another. The right-hand side expression (rhs) is converted to a string before concatenation. It is functionally equivalent to,
lhs = lhs & rhs
where the result is assigned back to the left-hand side string.
This operator can be overloaded for user-defined types.
Note: This operator exists in C/C++ with a different meaning - there it performs a bitwise And=.
Example
Dim s As String = "Hello, "
s &= " world!"
Print s
s &= " world!"
Print s
will produce the output:
Hello, world!
Dialect Differences
- In the -lang qb dialect, this operator cannot be overloaded.
Differences from QB
- New to FreeBASIC
