In which memory is stored each instruction?

Hello ,
I have as a program this example :

#include <stdio.h>
#define LAST 10

int main()
{
int i, sum = 0;

for ( i = 1; i <= LAST; i++ ) {
sum += i;
} /*-for-*/
printf("sum = %d\n", sum);

return 0;
}

And I want to know in which memory is stored each instruction.
for example :
==> int i, sum = 0; is stored in RAM
so what aboute the others?

Thanks.

The program gets stored in program ROM. Variables (i.e. int, char, etc etc) get stored in RAM during program execution.

So all the program is stored in ROM except ''variables"?
And ROm you mean flash memory of my microcontroller !!

The flash memory of the microcontroller is a contiguous space which contains both the program ROM space as well as the data EEPROM space and the configuration word. The program instructions get stored in the program space within the flash ROM. The data EEPROM section of flash ROM can be used for permanent storage of user settings while RAM is used for variables during program execution. With the proper code routines, the microcontroller can write to as well as read from the data EEPROM space in the flash memory but special code routines are required to do this.
