guys help why the value of oHM=HM*a;oMS=MS*b; oMs=Ms*c; is 0.000 can you help me how to get the correct output tnks

guys im newbie and i dont have any idea for know aout programing

a, b and c do not have a value assigned to them and you are using them.

I think this is how you want the program structured.

Compare what I have to what you have closely because you made many errors and I didn't comment all of them in.

#include <cstdio> //dont use name.h headers use cname headers
#include <conio.h>

float HM = 67.50, MS = 87.00, Ms = 92.75, a, b, c; //change data type to float or double ints do not have decimals
float oHM, oMS, oMs, T;
int main() //always use int main() not void main()
{
	printf("Hi! May I take your Order?");;
	printf("Here's our Menu");
	printf("Happy Meal for 67.50, McSavers1 for 87.00, McSavers2 for 92.75\n");
	printf("How many Happy Meal do you want?\n");
	scanf("%f", &a);
	oHM = HM * a; //figure out oHM after you get a value for a
	printf("It would be for %f\n", oHM);
	printf("How manyMcSavers1 do you want?\n");
	scanf("%f", &b);
	oMS = MS * b; //figure out oMS after you get a value for b
	printf("It would be for %f\n", oMS);
	printf("How many McSavers2 do you want?\n");
	scanf("%f", &c);
	oMs = Ms * c; //figure out oMs after you get a value for c
	printf("It would be for %f\n", oMs);
	T = oHM + oMS + oMs; //total everything up once you get values for oHM oMS and oMs
	printf("Your total bill is %f\n", T);
	printf("Thank You. Come Again\n");

	getch();
	return 0; //add a return since it is int not void
}
