First i want to know whats the difference between scanf(); and getchar();
second can anyone please write 2 examples, 1 with getchar/putchar and one with scanf which would take a name and print it all. i was able to do it with getchar/putchar but it printed only the first letter of the name.
Thanks!
Read the FAQ, or your C book. Or look at the man page, or look at a search engine. getchar reads one character. scanf reads specifically formatted input.

Hope is the first step on the road to disappointment.
So i cant use getchar to get all the input and print it ?? and in scanf how can i make it scan the input and print it out ?? can you write an example ?
Thanks
you can use getchar to get all of your input, you will just get the input one character at a time.
your question about scanf should be covered in any basic scanf tutorial
getchar works better for strings and characters. scanf works better with integers. Here's some examples.
Code:#include <stdio.h> main() { char x; x = getchar(); putchar(x); putchar(0x0a); }0x0a is the newline character, if you didn't know that.Code:#include <stdio.h> main() { char x; scanf("%c", &x); printf("%c", x); printf("\n"); }
Code:#include <stdio.h> int main() { char x; x = getchar(); putchar(x); putchar('\n'); }Much better. Implicit main is deprecated. Magic numbers are evil.Code:#include <stdio.h> int main() { char x; scanf("%c", &x); printf("%c", x); printf("\n"); }

Now we shouldn't you be able to? '\n' is a char, just like x that you also pass in.
I thought you could only do a '\n' with printf.
You can use a char's value anywhere you use an integer for the most part. You can put that value into any function expecting a value where that might fall into valid context. Let's say that '\n' has the decimal value of 10 (because it does.) If you write a function that expects you to pass it 1 through 10. You could pass it '\n' instead. It's just a value. Use it wherever you want.
Quzah.Code:putchar( '\n' );
