Difference between x++ and x+=1?

Question

For example:
Int x=5;
x++ //x=6=>5
x+=1 //???

Answer 1

In this case there's no difference, because the incremental assignment operator adds 1 to x. However, the post increment operator ++ can only be used to add 1 to the operand, while incremental assignment operator can be used to add any expression or value, e.g x += 5, or x += y * z.

Answer 2

no difference

x=5

x+=1
x=6

x++
x=6

as adding or subtracting 1 is very very common, ++ and -- are just shorthand. quick ways to say +=1

The real difference isn't in what they do, but when they do it. notice in this example printing x+=1 results in the new value, while printing y++ simply prints y and then adds the value the second time y is printed it has the new value

Answer 3

Eh... The increment operation (x++ or ++x) modifies the variable value and returns itself while x+=1 just returns the value of the expression whilst not modifying it.

Answer 4

To add on, x+=1 is short for x=x+1, so as already mentioned you can use any value in place of 1 but as used by you above the effect is the same.
x++ exists because programmers increment variables a lot, & a lot of the time it's by 1. x=x+y also comes up a lot, hence the x+=y shorthand.
