GO中的第二个scanf跳转扫描[重复]

Question

This question already has an answer here:

• Why doesn't fmt.Scanf in Go wait for user input? 1 answer

Dears,

I am writing some basic programs that need to receive more than one variable, following the formed

fmt.printf ("Report number")
fmt.scanf ("%f", &num1)
fmt.printf ("Report number")
fmt.scanf ("%f", &num2)

But the second scanf is always skipped, if I put a third, it is read normally. How do I do it, so that all Scanfs are recognized?

Answer 1

If you expect to end the read after hitting an enter, you want to add a new line into your format

fmt.printf ("Report number")
fmt.scanf ("%f
", &num1)
fmt.printf ("Report number")
fmt.scanf ("%f
", &num2)
