.... need help with my c code please?

#include %26lt;stdio.h%26gt;





typedef enum {FALSE, TRUE} BOOL;





void main(void)


{


// Mainline Variable Declarations


// FILE * output = stdout;


// FILE * input = stdin;





char name[20]; //length limited upto 20 chars only


printf("Enter name:");


scanf("%s",name);








// type int needed for 400,800,1600,3200


int ISO=0;


// type float needed for 2 2.8 4 5.6 8 11 16 22


float aperture=0;





BOOL ReadSpeed = FALSE;


BOOL ReadAperture = FALSE;





while ((ReadSpeed == FALSE) || (ReadAperture == FALSE))


{


if (ReadSpeed == FALSE)


{








printf("Hello %s Enter ISO setting: ");


scanf("%d",%26amp;ISO);


// flush the input stream in case of bad input


fflush(stdin);


printf("\n");


............


The line printf outputs like this when I compile it :


Hello %26lt;null%26gt; Enter ISO setting . Anyone know what I'm doing wrong ?

Change that printf statement to:





printf("Hello %s Enter ISO setting: ", name);
Reply:I think you meant to print "Hello (name) Enter ISO settings: ", so you need to write printf like this:





printf("Hello %s Enter ISO settings: ", name);
Reply:Get rid of the %s placeholder. C is expecting a string argument and you aren't passing one, hence the NULL. You're lucky, this would crash on some systems.
