Need a little help with my calculator program

[Gamemaster007]

I've made a simple Calculator program.The program is working fine except one thing.
After running the program it asks me to enter choice.Now suppose I enter
1.and then enter two numbers and add,After addition instead of showing "Enter you choice" it shows-
"Enter your choice
Not a good choice"
So my question is how should I remove this extra "not a good choice"?

  #include <stdio.h>
int main()
{
	int a,b,c;
	char x;
	printf("What would you like to do\n");
	printf("1. Addition\n");
	printf("2. Multiplication\n");
	printf("3. Division\n");
	printf("4. Subtraction\n");
	for(;;)
	{
	printf("Enter your choice- 1,2,3 or 4\n");
	x=getchar();
	if(x=='1')
	{
		printf("Enter two numbers\n");
		scanf("%d""%d",&a,&b);
		c=a+b;
		printf("The answer is %d \n",c);
	}
	else if(x=='2')
	{
		printf("Enter two numbers\n");
		scanf("%d""%d",&a,&b);
		c=a*b;
		printf("The answer is %d \n",c);
	}
	else if(x=='3')
	{
		printf("Enter two numbers\n");
		scanf("%d""%d",&a,&b);
		c=a/b;
		printf("The answer is %d \n",c);
	}
	else if(x=='4')
	{
		printf("Enter two numbers\n");
		scanf("%d""%d",&a,&b);
		c=a-b;
		printf("The answer is %d \n",c);
	}
	else
	{
		
		printf("Not a good choice\n");

	}
	}
	return(0);
}

getchar reads just one character from the input stream buffer, but whenever you type a value, you are actually typing 2 characters:

The number and a newline...
At the end of your for-loop, write:

getchar();
This will read the newline character and discard it since you do nothing with it or you can implement one of the methods in the 2 links above
