C语言数组输出间隔
#include stdio.hvoid main(){ void sort(int array[],int n); int a[10],i; printf("enter the array:\n"); for(i=0;i10;i++) scanf("%d", sort(a,10); printf("The sorted array:\n"); for(i=0;i10;i++) printf("%d",a[i]); printf("\n");}void sort(int array[],int n){ int i,j,k,t; for(i=0;in-1;i++) { k=i; for(j=i+1;jn;j++) if(array[j]array[k]) k=j; t=array[k];array[k]=array[i];array[i]=t; }}程序呢,就是这个了。谭老爷子书上的例题,和书上一样,然后输入:5 7 -3 21 -43 67 321 33 51 0 然后从小到大排好后输出,书上他们之间从小到大有间隔,但是我运行了,没有间隔。。。。( ⊙o⊙ )?咋解决?????来高手解答。。。我运行后是:-43-305721335167321
