[previous] 0207 [next] [U] 'scanf' expects address of objects being stored into.
Explicitly undefined REFERENCE - ISO:C90-7.9, ISO:C90-7.9.6.4 - The scanf Function

An argument in this scanf/sscanf/fscanf function call is not of the correct type. It should be of "pointer type" in order to receive the data object which is being fetched.

For example: 


/*PRQA S 336,602,1302,1307,2017,3122,3200,3209,3227,3408,3602,3625 ++*/

#include <stdio.h>

extern void foo(void)
{
    int n;

    scanf("%d", &n);              /* OK           */

    scanf("%d", n);               /* Message 0207 */
}
