Hi Everyone,
I'm getting the error Lvalue required when I'm compiling the following program
When i changed the line to the following it is runnig fine.Code:#include <stdio.h> int main() { int a=1,b,c; clrscr(); c=(a>5)?b=5:b=4; /* here it is giving the error */ printf("c=%d\tb=%d\n",c,b); getch(); return 0; }
can anyone explain to me what is the reason for the error in the first case.Code:c=(a>5)?b=5:(b=4);
Regards,
So are you trying to set both b and c to the same value?
Quzah.Code:c = b = a > 5 ? 5 : 4;
Hope is the first step on the road to disappointment.
Still the code seems correct...
c = (condition)?expression:expressiom;
I think the compiler is grouping symbols like this
c=(a>5)?b=5:b=4;
c=expression=4;
but it shouldn't

Actually yes, that's what it is doing, and it should. The ? : is resolved right to left, before the = is.
