# include <string.h>

int a = 1;
int *iamstring =NULL ;
iamstring = &a; //this assignment makes the error code :  'iamstring' does not name a type

void setup() {
  Serial.begin(9600);
}

void loop() {
  Serial.print("first iamstring without *"); 
  Serial.println(iamstring); //suppose to show the memory address
  Serial.println("now iamstring with *");
  Serial.println(*iamstring); //suppose to show the value
}

//thanks for helping

you can't have code outside of function. move the line to setup()

Why not simply

int *iamstring = &a;

?
