Experimental results:

#include <stdio.h>#defineN 100intMain () {inti,num[n]={0},a=0;  for(i=0; i<n;i++) {Num[i]=i+1; }     for(i=0; i<n;i++)    {        if(num[i]%3==0|| num[i]%7==0) {Num[i]=0; }        Else{a++; printf ("%5d\n", Num[i]); }} printf ("It Remaid%d numbers", a); return  0;}

Operation Result:

This experiment summarizes:

After the experiment code is written, there are a lot of small errors, such as when using the function, after adding '; ', ' for The Loop ', ' instead of '; ',

However, the idea of the first code is quite clear and not confusing.

The second code at first did not know how to start, although the teacher said in class, but there is no idea = =. But after seeing the classmate, I understood ...
