例如:判断输入的任意整数n能否被3整 除,程序如下: maino iint n; printf(n enter a integer scanf(%od",&n); if(n%3==0) printf("n %d can be divided by 3, n); else printf( in od can't be divided by3",n);例如：判断输入的任意整数n能否被3整 除，程序如下： main() { int n; printf("\n enter a integer:"); scanf("%d", &n); if( n%3==0) printf("\n %d can be divided by 3" , n); else printf("\n %d can't be divided by 3", n); }
