What does x = (a<b)? A:b mean in C programming?

x = (a<b) in C programming is a conditional assignment statement. It assigns the value of either A or B to X based on the result of the condition (a<b).

Step 1: Evaluate the condition (a<b). If the condition is true, the value of the expression is 1. Otherwise, if the condition is false, the value of the expression is 0.

Step 2: Assign the value of the expression to X. If the condition is true, X will be assigned the value of A. Otherwise, if the condition is false, X will be assigned the value of B.

Here's an example to illustrate this:

int a = 5;
int b = 10;
int x;

x = (a < b) ? a : b;

In this example, the condition (a < b) is true because 5 is less than 10. Therefore, the value of X will be assigned the value of A, which is 5.

So after executing the above code, the value of X will be 5.

If the condition (a < b) was false, for example, if a was 15 and b was 10, then the value of X would be assigned the value of B, which is 10.
