x=3 y=4 I don’t understand

Question

x<=y Why is true

Answer 1

If x<=y is true.

So it’s very simple. The comparison of strings is the ASCII value. The ASCII value of the letter x is 120 and the ASCII value of y is 121.

Then 120<=121 must be correct, so it is true .

Answer 2

First bring x and y into x<=y. Is it 3<=4? Is this inequality true? In programming, we call such an inequality an expression. The expression has only two values, true and false. , if this inequality is true, the value of this expression is true, if not, it is false
