Infinite Loop In My Code

[javacvb]

Hi,

I am new to programming. I am a self taught programmer wannabe. I have no one to consult except books so I think joining this forum would be great.

Could someone tell me why the program below will continue looping after I entered any number with decimal point?

#include <stdio.h>

int main()
{
	float average;
	float counter, grade, total;
	total =0;
	counter = 0;

	printf("Enter grade, -1 to end: ");
	scanf("%d", &grade);

	while(grade != -1)
	{
		total = total + grade;
		counter = counter + 1;
		printf("Enter grade, - 1 to end: ");
		scanf("%d", &grade);
	}

	if (counter !=0)
	{
		average =  total/counter;
		printf("Class average is %.2f", average);
	}
	else 
		printf("No grades were entered");
	return 0;
}

Also could you let me know whether the MFC features in Visual C++ 6 could be used with C ?


Is there any IDE software out there that you can use to build GUI forms with C like the drag & drop forms that you see in Visual Basic 6, Visual C++, & JBuilder? If there is none, could you tell me where I can learn (from the internet) writing GUI programs with C?



Thanks for taking the trouble to reply to me.

grade is float,so scanf looks like this

scanf("%f", &grade);

Counters should be integers.

MFC = Microsoft Foundation Classes
C does not have classes.

Therefore, no.
