yes, in the case of the the expression
the sequence point is the ; at the end of the statement when "it is guaranteed that all side effects of previous evaluations will have been performed, and no side effects from subsequent evaluations have yet been performed", i.e when are ++a operands evaluated? you don't know they are all evaluated until the sequence point and different compilers etc give different... -
using Visual Studio you can implement a DLL containing C++ functions which can be called from a VB.NET program, see

The C standard does not specify the order in which the operands (suh as ++a) of an operator (such as the + in ++a + ++a) are evaluated and there is no guarantee when an affected variable will change its value.
consider
however, when are the ++a operands evaluated?Code:int a=1,c=1,d; int b=++a + ++a + ++a;
1. the ++a operands of (++a + ++a) evaluated and the result added then the final ++a evaluated and added? the...Leave a comment:

if you are implementing a strcpy() you don't need the length parameter, try this
or evenCode:int i=0; for(i=0; src[i]!=0; i++) dest[i]=src[i]; dest[i]=0; printf("out %s",dest);
if the source does not contain a 0 you end up corrupting...Code:int i=0; do dest[i]=src[i]; while(dest[i++]!=0); printf("out %s",dest);Leave a comment:

lines 20 and 21
if src[i] is not a '\0' will go into an endless loopCode:while(src[i]!='\0') dest[i]=src[i];
remove line 20Leave a comment:

you cannot assign the elements of a struct so
you can assign each element soCode:item[0]={"rice",10,40,30};
or when you declare you can give it initial valuesCode:item[0].quantity=10; item[0].retail=40;
...Code:struct item_info { char itemname[15]; int quantity; float retail; float wholesale; //intLeave a comment:

Visual Studio VB.NET has a Timer component which you can configure to create an event every 3 secondsLeave a comment:

convert the cmd.comando to an int then use that in a switch?
if the cmd.comando values of are ASCII characters you will need to subtract '0' in each caseCode:int i=cmd.comando[0]*100+cmd.comando[1]*10+cmd.comando[0]; switch (i) { .....Leave a comment:

16bit is Half precision floating point and in the IEEE format the mantissa is 9 bits and gives approximately 3 decimal digits of significant precision.
for example, see documentation on the ARM microcontroller

and gcc compiler documentation
