Use of menus in C

[easg]

I need to create this program but using menus, but I dont have an Idea of how create menus in C, I know how to use the case function but I don`t know how to build the menu,

#include
#include

void main (void)
{
float mts, km, ton, qq;

printf ("Programa de conversion");
printf ("Digite la cant de km: ");
scanf ("%f",&km);
mts = km*1000;
printf ("Los %.2f km equivalen a %.2f mts", km, mts);
printf ("Digite la cant de QQ: ");
scanf ("%f",&qq);
ton=qq/10;
printf ("Los %.2f qq equivalen a %.2f ton",qq,ton);
getch ();
}

Do you want just a regular text menu with numbers for several choices? Here is an excerpt from one of my programs which has a menu based user interface:

while(c != 0)
{
	printf("Choose the mode\n");
	printf("(1) User defined values\n");
	printf("(2) Walk\n");
	printf("(3) Bounce\n");
	printf("(0) Quit\n");
	printf("------------------------\n");
	scanf("%d", &c);


	switch (c) {
		case 1: UserDef(); break;
		case 2: Walk(); break;
		case 3: Bounce(); break;
		case 0: break;
		default: system("cls"); printf("That is not a valid choice\n\n"); break;
	} 
}

This example is ok, thank you.
