Error: format specifies type ‘char’ but the argument has type ‘string’

[admin]

This is the code written:

[dm_code_snippet background=”yes” background-mobile=”no” slim=”yes” line-numbers=”yes” bg-color=”#abb8c3″ theme=”dark” language=”clike” wrapped=”yes” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]

#include <stdio.h>
#include <cs50.h>
int main(void)
{
string name = get_string ("what is your name\n");
scanf("%s", &name);
printf("%s",name);
}

[/dm_code_snippet]

On typing help50 make hello command, I get this suggestion:

format specifies type 'char *' but the argument has type 'string *' (aka 'char **') [-Werror,-Wformat]
scanf("%s", &name);
       ~~   ^~~~~

Be sure to use the correct format code (e.g., %i for integers, %f for floating-point values, %s for strings, etc.) in your format string on line 6 of hello.c. ~/pset1/hello/ $

Do I need to remove string type and instead use char type. If so, why?

[dm_code_snippet background=”yes” background-mobile=”no” slim=”yes” line-numbers=”yes” bg-color=”#abb8c3″ theme=”dark” language=”clike” wrapped=”yes” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]

#include <stdio.h>
#include <cs50.h>
int main (void)
{
int number;
scanf ("enter a number %i", &number);
printf ("the number is %i", number);
}

[/dm_code_snippet]

Here is the result as I enter 44:

~/pset1/ $ ./Mario
44
the number is 0~/pset1/ $
