Since there are many statements changing the value of the variable, this won't be a practical solution.

int main(void){
   int myVariable;
   
   SetMyVariable(myVariable, 0);

   SetMyVariable(myVariable, 345);

   return 0;
}

void SetMyVariable(int variable, value){
   variable = value;
   cout<<"myVariable has the value "<< value;

   return;
}
