First one is present increment and second one is the post incremental t of the variable. Both increases value of var to one. The difference between pre and post increment is given in below example. Int a=10. Int b=++a Then a and b both have the value 11. If b=a++ Then a become 11 and b have 10...

first one is pre incrementing, second one is post incrementing. Lets take an example; int a,b=10, c; a=++b; c=b++; The values you get will be a=11; b=12, c=11; In case of pre-incrementation, increment happens first, then assignment. In case of post increment, assignment happens first and then...

In case of post increment, assignment happens first and then increment; That is why b is incremented twice but a and c got values based on when the increment is performed. read less

++var -- is for pre-increment, var++ -- is for post increment you will only see the effect when you are assigning this kind of operation to another variable, say int var=10; int i=0; i=++var; // here value of var(10 is incremented and then assigned to variable i, so i and var will be 10 now) var=10; i=var++;...

++var is pre increment.var++ is post increment.Alone if we see pre/post increment there is no difference.variable will get incremented by 1. We can see the difference between pre/post increment only if we use with assignment operator.++var meaning is first increment then assign.var++ meaning is first...

The ++var is pre-increment whereas var++ is post increment. In case of pre-increment, the variable's value is incremented first and the same incremented value is used in evaluation of the current expression whereas in case of post-increment, the existing value of variable is used in evaluation of the...

Let suppose var=3 and we do these two things: 1. a=5; 2. a=5; In first case, first var value will get incremented by 1 and then value 5 is assigned to the array. In second case, first value is assigned to array and then var value will get increment. In first case, value 5 is assigned to a and final...

Let suppose var=3 and we do these two things: 1. a[++var]=5; 2. a[var++]=5; In first case, first var value will get incremented by 1 and then value 5 is assigned to the array. In second case, first value is assigned to array and then var value will get increment. In first case, value 5 is assigned to a[4] and final value of var is 4. In second case value 5 is assigned to a[3] and then value of var is increased to 4. In both case, final value of var is 4 but just the value of a[3] and a[4] are different. read less

I am a teacher.

See below example; int var==10; int c,d; c=var++; # value of 'c' here is 10, var is incremented to 1 i.e. 11; var=10; #resetting 'var' value to 10 for your better understanding. d=++var; # value of 'd' here is 11. Even var value also 11. in case of ++var, value of 'var' will be first incremented...

Even var value also 11. in case of ++var, value of 'var' will be first incremented and then assigned to the lvalue (in above e.g. 'd') in case of var++, first 'var' value will be assigned to the lvalue and then 'var' will be incremented (in above e.g. its 'c'). Kindly let me know if you need still more clarification. read less

++var is pre- increment operator. For eg-if var=5 then ++5 means 5+1 i.e. 5 will first increase by 1, become 6 and then will do any work. But var++ means post-increment operator. For eg.- if var=5, then 5 will first do any work like entering a loop or addition, multiplication, etc. after this value of...
