Question { 16053 }

what is the output of the following program?
#include
void main()
{
int x=4,y=3,z;
z=x-- -y;
printf("\n%d %d %d",x,y,z);
}

Answer

given z=x-- -y
therefore x--=4-1=3;
and given y=3;
so z =3-3=0;
but x doesn't change its value.
so the correct answer is 430

Is main() function predfined or userdefined?

Answer

main() is a predefined function because compiler starts
executing only in main() function. It better to press F7
function key after compiling your program because the
control first passes only to main() function
