Thread: errors in multi-selection program

Code:

#include <stdio.h>

int getOption (void);

float add2 (float num1, float num2);
float sub2 (float num1, float num2);
float mul2 (float num1, float num2);
float div2 (float num1, float num2);

void pirintResult (float num1, float num2, float result, int option);

int main (void)
{
	int   done = 0;
	int   option;
	float num1;
	float num2;
	float result;

	while (!done)
	{
		option = getOption();
		if (option == 5)
			done = 1;
		else
		{
			do
			{
				printf("\n\nEnter two numbers: ");
				scanf ("%f %f", &num1, &num2);
				
				if (option == 4 && num2 == 0)
				{
					printf("\n\n *** Error *** ");
					printf("Second number cannot be 0\n");
				} while (option == 4 && num2 == 0);

			switch (option)

			}
		}
	printf("\nThank you for using this Calculator.\n");

	return 0;
}

int getOption (void)

{
	int option;

	do
	{
		printf("\n***************");
		printf("\n*     MENU    *");
		printf("\n*             *");

		if (option < 1 || option > 5)

Why do I keep getting errors with this program?

That's a good question. How about you do us all a favour and post what errors you are getting?

Quzah.

You're always mean to me, Quzah.

Well, how about you copy the code into your compiler to see the errors for yourself?

Copy and paste shouldn't be too much of hassle, no?

Ok, ok, i'll post the errors:

warning C4013: 'printResult' undefined; assuming extern returning int

printResult (num1, num2, result, option);


error C2059: syntax error : '}'

printResult (num1, num2, result, option);
}
}


error C2143: syntax error : missing ';' before 'type'

int getOption (void)
