第四阶段—数组—数组初始化：让用户在数组的某个位置插入某个数

#include<stdio.h>

int a[8] = {0};
void main(){
    int i;
    int num,data;
    printf("please input 7 number:");
    for(i = 0;i < 7;i++)
    {
     //printf("please input di%d number:", i+1);
     scanf("%d",&a[i]);
    }    
    // printf("please input one weizhi number:");
    // scanf("%d",&number);
    // printf("please input one weizhi number:");
    // scanf("%d",&data);
    printf("please input you want insert position and data:");
    scanf("%d%d",&num , &data);
    for (i =7;i > num-1;i--){
        a[i] = a[i-1];
    }
    a[num-1] = data;

    for(i = 0;i < 7;i++)
    {
         printf("%d ",a[i]);         
     }
     printf("\n");
    return;    
}
