Using fgets?

Hey,
i ahve asked you some days before how to use scanf to add string
but i think that if you use fgets you can take strings faster
the problem is i don't know how to get a string
for example i got this:

Code:

#include <stdio.h>

main()
{
printf("Hello, what is your name?");
fgets(name, sizeof name, stdin);
printf("Your name is %s", name);
}

this code isn't working and i don't know why?
please help me using fgets
thanks

Well, it could be because you haven't declared name anywhere. Did you read your compiler errors?

Code:

itsme@dreams:~/C$ cat noname.c
#include <stdio.h>

main()
{
printf("Hello, what is your name?");
fgets(name, sizeof name, stdin);
printf("Your name is %s", name);
}
itsme@dreams:~/C$ gcc -Wall noname.c -o noname
noname.c:4: warning: return-type defaults to `int'
noname.c: In function `main':
noname.c:6: `name' undeclared (first use in this function)
noname.c:6: (Each undeclared identifier is reported only once
noname.c:6: for each function it appears in.)
noname.c:8: warning: control reaches end of non-void function
itsme@dreams:~/C$

Check out the lines I bolded.

because you have not reserved a place in memory to store that string. You know how to declare a string right? if so , then declare name as a string first . If not , then read about strings first.

You've also declared function main as 'main()' without a return value. You should explicitly declare 'main' as an int (int main) and let it return a value to indicate successful execution (typically 0), so your program would look like this :

Code:

#include <stdio.h>

int main()
{
/* code here */

return 0;
}

btw , your compiler shows errors for a reason..
