....FOR Loops Increment and Decrement Formats...

Question

For example=>
compare these two formats
int a;
[ a++ , ++a a-- , --a ] and [a=a+1 , a=a-1]
QUESTIONS=>
# What are the differences between these two groups ?
# In what situations are they best applied ?
# Can both be used interchangeably ?
# Will both produce same results ?

Answer 1

Run this program you get better idea.
#include <iostream>
using namespace std;
int main() {
int a=1;
for(int i=0;i<5;i++
cout<<a++<<"\t";
cout<<"\n";
a=1;
for(int i=0;i<5;i++)
cout<<++a<<"\t";
return 0;
}

Answer 2

hear
a++ 1st print the value of a and then increment by 1.
And
++a 1st increment by 1 and then print the value.
it similar for a-- And --a.
And
the answer of a++ and a=a+1 is same
and similarly a--and a=a-1.

Answer 3

pull up and dab

Answer 4

syntax:
for(int i=initialization;i<conditions;i++ori-- increment or decrement)
{}
