It just changes when the increment occours...If the line has ++x, then x is incremented before the line is evaluated. If the line has x++, then the line is evaluated before x is evaluated.Code:#include <stdio.h> int main () { int x = 3; printf ("%d x\n", x); // Prints 3 printf ("%d x++\n", x++); // Prints 3 again, then increments x to 4... printf ("%d x\n", x); // x is now 4, so prints 4. printf ("%d ++x\n", ++x); // Increments x to 5, then prints x (5) printf ("%d x\n", x); // x is now 5, so prints 5 return 0; }
Callou collei we'll code the way
Of prime numbers and pings!
Very elegant explanation there, QC! Kudos!
Code:int main(void){srand(time(0));for(double l=rand(),l0=0,l00=0;;l0+=0.1){for(double l000=0;l000 <1;l000+=.001,l+=((double)rand()/RAND_MAX)/0x64,l00+=((sin(l*0x8*atan(l0)*l000-(l0*0x8*atan (l)))*0.5)+0.5)){l00-=floor(l00);for(size_t l0000=0,l00000=(size_t)(0x50*(l00));l0000<l00000;++l0000 )putchar(0x20);putchar(0x61+(int)((double)rand()/RAND_MAX*0x1a));putchar('\n');}}return 0;}
What???
