Need help formating scanf, please.

[ochen]

I'm new to C-programming.

Here's what I'd like to do:

The user inputs T47.2 Scanf recognizes T as a char and 47.2 as a floating point number.

This code doesn't work:

#include <stdio.h>
int main() {
char letter;
float number;
while(1) {
printf("Letter and Number: ");
scanf("%c%f", &letter, &number);
}
return 0;
}

I put the printf and scanf functions in an infinite loop so I can test various inputs.

It compiled successfully using c99, and here's what I get after three inputs:

>./a.out
Letter and Number: T47.2
Letter and Number: J73.8
Letter and Number: Letter and Number: I99.1

Something isn't working as I intend for it. It's as if "J" and "73.8" are treated as two separate inputs.

I'd greatly appreciate any input as to how I might fix my scanf format to function properly.

%c does not skip \n left by %f in the input stream
add space after %f to skip whitespaces

Thanks, vart

I changed the statement to:

scanf("%c%f%*c", &letter, &number);

This accounts for the return character, while not assigning it.

You can use the following code

#include <stdio.h>
int main() {
char letter;
float number;
while(1) {
printf("Letter and Number: ");
scanf("%c %f", &letter, &number);
getchar();
}
return 0;
}
