The 11th Time lab work

First question

#include <stdio.h> void sort (int a[],int n); int main () {    int n,a[8];    int i;        printf ("Enter N (n<=8):");    scanf ("%d", &n);    printf ("Enter a[%d]:", n);    for (i=0;i<n;i++)    scanf ("%d", &a[i]);    Sort (a,n);    printf ("After sorted,a[%d]=", N);    for (i=0;i<n;i++)    printf ("%3d", A[i]);            return 0;} void sort (int a[],int n) {    int i,j,t;    for (i=1;i<n;i++) for    (j=0;j<n-i;j++)    if (a[j]>a[j+1])    {     t=a[j];     A[J]=A[J+1];     a[j+1]=t;}     }

Second question

#include <stdio.h>int search (int list[],int n,int x); int main () {    int n,x,list[10];    int i;        printf ("Input N:");    scanf ("%d", &n);    printf ("Input%d integers:", n);    for (i=0;i<n;i++)    scanf ("%d", &list[i]);    printf ("Input x:");    scanf ("%d", &x);    Search (list,n,x);    if (search (list,n,x)!=-1)    printf ("mid=%d\n", Search (list,n,x));    else    printf (" -1\n");        return 0;} int search (int list[],int n,int x) {    int i;    for (i=0;i<n;i++)    {    if (X==list[i])    return i;    else    return-1;    }        }

Third question

#include <stdio.h>int main (void) {    int count,i,m,n,no;    int num[50];    int *p;    printf ("Enter n,m:");    scanf ("%d%d", &n,&m);    for (i=0;i<n;i++)    num[i]=i+1;    P=num;    count=no=0;    while (no<n-1)    {    if (*p!=0) count++;    if (count==m)        {         no++;         printf ("Exit person%d:%d\n", no,*p);         *p=0;         count=0;        }        p++;        if (p==num+n)        p=num;    }    P=num;    while (*p==0)    p++;    printf ("Last Person:%d\n", *p);        }

The last question does not, ask the classmate, but still did not understand, intends to attend class listens to the teacher to speak.
