用循环语句实现从键盘输入四个数,组成一个四位数,先输入的在高位

#include int main(){int a[4];int i;printf("Please inpuet the 4 numbers:\n");for (i = 0; i < 4; i++){printf("Please Inpuet the %dth number。\n",i + 1);scanf("%d",&a[i]);}printf("the 4 number are:\n");printf("千位:%d\n",a[0]);printf("百位:%d\n",a[1]);printf("十位:%d\n",a[2]);printf("个位:%d\n",a[3]);printf("这个四位数是:%d\n",((a[0] * 1000) + (a[1] * 100) + (a[2] * 10) + a[3]));return 0;}
