What is the difference between x++ and ++x in c language

The difference is as follows:

x means that the value of x is incremented by 1 first, and then the value of x is calculated.

x is to first calculate the value of x, and then increase the value of x by 1.

Example:

int x=10;
System.out.println(x++);  
System.out.println(x);

The first one outputs 10, x first uses the value of x in the current expression, and then increases the value of x by 1, and the second one outputs 11, because After the previous instruction, x has increased by 1.

int x=10;
System.out.println(++x);
System.out.println(x);

The first one outputs 11, x first increments the value of x by 1, and then uses the value of x in the current expression. The second one also outputs 11, and x increases after the previous instruction. 1.
