# Use Ternary Operator
# Description
This rule replaces if-statements by equivalent constructs using the ternary operator in cases where such a replacement is reasonable. For example, the statement 'x = condition ? 1 : 0;' is shorter and better readable than the equivalent construct using an if-statement.
# Benefits
Code can be made shorter.
