Using -- and ++ Operators

Try to use only unary operators for incrementing and decrementing variables, because they produce fewer instructions and run faster, as you can see in the following example of code:

#include 
using namespace std;

int main() {
   
   int a,b,c;
   
     a=7;
   a--; 
   b=3+(a--);   
   c=--b*a--; 

   cout         
}

The output should be:
