Avoid the use of multiplies to optimize your code for speed (C/C++).
If it is possible you should use constant increments instead of multiplies. #include <stdio.h> #include <stdlib.h> int main(void) { int i, j; for(i=0; i<10; i++) { j=i*10; } } int main1(void) { int i, j; for(i=0; i<100; i+=10) {... Read more
