In C++, the conditional operator (also known as the ternary operator) can be used to assign a value based on a condition. This is commonly referred to as "this or that" or "if then else" statement. It has the following syntax:
(condition) ? true_expression : false_expression;
If the condition is true, the true_expression is evaluated and assigned to the variable. If the condition is false, the false_expression is evaluated and assigned to the variable.
Here's an example:
``c++
#include
using namespace std;
int main() {
int num = 10;
int x;
// Assigning "this" or "that" value based on condition
x = (num >= 10) ? 100 : 200;
cout << "Value of x: " << x << endl;
return 0;
}
num
In this example, we're initializing two variables:andx. We're usingxto store a value based on the condition(num >= 10). If the condition is true (i.e.,numis greater than or equal to 10),xwill be assigned the value100. If the condition is false,xwill be assigned the value200.numSo in this case, since
equals to 10, the condition is true, andxgets assigned the value100. The output would be:
Value of x: 100
