an example with cout is clearer: int x = 1,y = 1; cout x++; // outputs 1 then increments x by 1 cout ++y; // increments y by 1 then outputs 2

++x increments the value of x and then returns x x++ returns the value of x and then increments example: x= 0 ; a=++x; b=x++; after the code is run both a and b will be 1 but x will be 2.h

x++ means display and then update ++x means update and then display for example ; say x=3; so if you do x++ ; it shows the output 3 and then updates its value to 4 whereas for ++x; it first updates to 4 and then displays 4;
