increment operator

What's the main difference between two operators in the codes

Code:

---

#include<stdio.h>

int main ()
{
  int A = 1;
    A++;
 
  printf(" A = %d ", A);


    return 0;       
}

---

Output : A = 2

Code:

---

#include<stdio.h>

int main ()
{
  int A = 1;
    ++A;
 
  printf(" A = %d ", A);


    return 0;       
}

---

Output : A = 2

Both operators gives same output

In this context, i.e., when they are used standalone, there is effectively no difference. The differences only matter when they are used as part of a larger expression.
