Question

With the help of stack or any other way solve the following expression.With detailed explanation.
int x=5;
x=x++ + ++x + --x + ++x + x++ + --x + x++;
printf(x);

Answer 1

> x=46; :)

Analise this code:

#include <stdio.h>
#include <stdlib.h>
int main (void){
int x=5,
exp1 = (x++), // add 1 to "next x"
exp2 = (++x), // add 1 to this(now)
exp3 = (--x), // decrement 1 to this(now)
exp4 = (++x), // add 1 to this(now)
exp5 = (x++), // add 1 to "next x"
exp6 = (--x), // decrement 1 to this(now)
exp7 = (x++); // add 1 to "next x"
printf("x=x++ + ++x + --x + ++x + x++ + --x + x++;\n");
printf("x=%3d + %3d + %3d + %3d + %3d + %3d + %3d;\n",exp1,exp2,exp3,exp4,exp5,exp6,exp7);
printf("x=%d\n",exp1+exp2+exp3+exp4+exp5+exp6+exp7);
}
