I don’t understand scanf()

Can you help me with scanf() i don’t understand.

Answer 1

Scanf() is to input integer or char or any data type.

Example :
int n;
scanf("%d", &n);

You can input any integer for variable n, example you input 5
So, if you print it like this:

printf("%d", n);

the output will be 5.
