debug之后发现输入似乎没有问题，但是debug运行到printf函数就停了，按了几次下一行没反应，然后退出了。

Question

卧槽刚刚想截屏运行了一次，又有输出了，结果如图

#include<stdio.h>
#include<malloc.h>
#define MAX 100

 int hang,lie;
 int value;

typedef struct{

void scanfTSM(int i,TSMatrix P)//输入
{
  int r,c,v;
 for(int j=0;j<i;j++){
    scanf("%d%d%d",&r,&c,&v);
    P->data[j].hang=r;
    P->data[j].lie=c;
    P->data[j].value=v;
     }
     P->nonezero=i-1;
