Can you kindly explain this?

Question

https://code.sololearn.com/cbVyZnxD3evw/?ref=app
input <= 45g65
output => 4565
input <= 45gjsb65
output => 450
input <= 45
output => 450
Suppose, I just want to remove any number of character inside a digit, where to make change?
And why it puts 0 if I enter 45hvsg65 or 45, why not 4500?

Answer 1

I don't think you can use scanf placeholder format argument to achieve more than skipping a fixed number of char before getting another number...

you rather have to get the whole line input as string and extract numbers from it by yourself ^^

As visph said ,get input as string then scan the string ,check if any isalpha(c) there, if yes remove it or print only if isnum(c) is there
