[previous] 1253 [next] Unsuffixed integer constant implicitly converted to different integer type.
Arithmetic type - Balancing

In the course of a type balancing operation, an unsuffixed integer constant is being implicitly converted to another type. The type conversion is largely academic but addition of a suffix might promote additional clarity.

Note that the type of an integer constant depends on its value and the implemented size of an int (e.g. whether it is a 16 bit or 32 bit quantity) as well as the presence of suffixes. More ...

For example: 


/*PRQA S 2017,3112,3120,3408,3447,3602 ++*/

extern unsigned int  uia;
extern signed long   sla;
extern unsigned long ula;


extern void foo( void )
{
    uia + 5;               /* Message 1253 */
    sla + 5;               /* Message 1253 */
    ula + 5;               /* Message 1253 */
}
