Hi,

I have many menu sections which will display on LCD depending on the input parameter. Below is the sample.

Code: 
void main_menu()
{
	int i;

	switch(i)
	{	
		case 1:	printf("text1");
			break;

		case 2:	printf("text2");
			break;
		.
		.
		.
	
		case 5: printf("text5");
			break;	
	}

	if(i == 1)
		// do some action

	else if (i == 2)
		// do someother action

	.
	.
	.
}

void sub_menu()
{
	int i;

	switch(i)
	{	
		case 1:	printf("text1");
			break;

		case 2:	printf("text2");
			break;
		.
		.
		.
	
		case 5: printf("text5");
			break;	
	}

	if(i == 1)
		// do some action

	else if (i == 2)
		// do someother action

	.
	.
	.
}

void sub_menu1()
{
	.
	.
	.	
}
// submenus goes on

Is this the efficient way of programming the menu structure? Or any other methods available to reduce the memory size and faster execution of program.
 

Yes, it is optimal from memory consumption point of view, but it is not flexible.
Do you think you are good enought to start using pointers and structures?
 

Why do not do the action after the printf on case 1 for instance?
