C程序设计上机实验操作题参考答案(5)

return 0; }

#include #define N 10

void sort(int *p, int n) { int i,j,k,temp; for(i=0;i*(p+j)) k=j; if(k!=i) { temp=*(p+i); *(p+i)=*(p+k); *(p+k)=temp; } } }

int main() { int a[N],i; printf(\输入%d个数：\ for(i=0;i

#include #define N 20 float data[N]={0}; int num=0;

int insert(float a) { if(num

}else return 0; }

int delete(int index) { if(index>=0 && index<(num-1)) { memmove(&data[index],&data[index+1],(num-index-1)*sizeof(float)); num--; return 1; }else return 0; }

void sort() { int i,j; for(i=0;i

void printData() { int i; for(i=0;i

写程序显示如下菜单

1. insert (插入一个数据) 2. delete (删除一个数据) 3. sort (排序)

4. print (输出表中所数据) 0. exit (退出程序)

void printMenu() { printf(\插入数据\\n\ printf(\删除数据\\n\ printf(\排序\\n\ printf(\打印数据\\n\ printf(\退出程序\\n\ printf(\}

int main(int argc, char *argv[]) { int cmd=0; while(1) { printMenu(); scanf(\ switch(cmd) { case 1: { float a; scanf(\ insert(a); break; } case 2: { int index; scanf(\ delete(index); break; } case 3: { sort(); break; } case 4: { printData(); break;

} case 0: exit(); } } return 0; }
