Why I can't get the correct result

[348892813]

I am a student learning C language, I know many of you are good at it.
I need your help.Thank you.
I want to type in a to choose addition, butI can't get the result.
#include <stdio.h>
int main()
{
char character;
float fnum,snum;
printf("Please type in a number:\n");
scanf("%f%f",&fnum,&snum);
printf("Please type in another number:\n");
scanf("%f",&snum);
printf("Enter a select character: ");
printf("\n a for addition");
printf("\n b for multiplication");
printf("\n c for division");
scanf("%c",&character);

switch (character)
{
case 'a':
printf("The sum of the number entered is %6.3f\n",fnum+snum);
break;
case 'b':
printf("The product of the numbers entered is %6.3f\n",fnum*snum);
break;
case 'c':
if(snum != 0.0)
printf("The first number divided by the second is %6.3f\n",fnum/
snum);
else
printf("Division by zero is not allowed\n");
break;
}

return 0;

}

are you sure you are reading the values correctly? You won't get the
correct result if you don't retrieve the correct values. Try to print
them out to check them.
