How to get user input in c.. As a+b.. As like java scanner.. How in c

Question

Mm..

Answer 1

Some functions work great in C

The easiest way is scanf that allow you to read any type but breaks your program if the type is wrong (you asked for an int and got some letters)

Then there are functions for getting characters and strings :
gets, getc, getchar, ...
Those are safer but you'll have to convert the result to the type you want to have

Answer 2

fgets then, if you read online linux manual for those functions, you'll find lots of others with nearly the same behavior :)
