[说明]
函数Printprime(int UpBound)的功能是输出1到UpBound以内的全体素数。
[函数2.1]
void PrintPrime(int UpBound)
printf("2," );
for(i=3; i<UpBound; i+ =2) {
int k = sqrt(i);
for(j=3; j<= k;(1)) /*检查i是否有3到k以入的奇因数*/
if((2)) break;
fi((3)) printf("%d", i);
[函数2.2说明]
递归函数invert(int a[],int k),int k)的功能是将数组a中的前k个元素逆置。
[函数2.2]
void invert(int a[ ], int k)
{ int t;
if ((4)) {
invert((5));
t=a[0];
a[0] =a[k-1];
