in c++ ++ how to write if without if
To write an "if" statement without using the actual "if" keyword in C++, you can use the ternary operator. The ternary operator is a conditional operator that takes three operands and evaluates a condition, returning one of two values based on the condition's result.
Here's how you can write an "if" statement without using "if" in C++:
(condition) ? true_statement : false_statement;
Let's break down the steps:
Condition: Start by specifying the condition you want to evaluate. This is similar to the condition inside an "if" statement.
Ternary Operator: Use the ternary operator
?
to indicate the start of the expression.True Statement: After the
?
, specify the expression or statement that should be executed if the condition evaluates to true.False Statement: Following the
:
, specify the expression or statement that should be executed if the condition evaluates to false.
Here's an example to illustrate the usage:
int x = 5;
int y = (x > 0) ? 10 : 20;
In this example, the condition (x > 0)
is evaluated. If it's true, the value 10
is assigned to y
. Otherwise, the value 20
is assigned to y
.
By using the ternary operator, you can achieve the same effect as an "if" statement without using the actual keyword "if".
