由键盘输入三个整数a、b、c,按从小到大的顺序输出这三个数

int main(int argc, const char * argv[])
{

int a[3] = {0};
printf("输入三个整数空格隔开:\n");
for (int i = 0; i < 3; i++) {
scanf("%d", &a[i]);

}

for (int i = 0; i < 2; i++) {
for (int j = 0; j < 2 - i; j++) {
if (a[j] > a[j + 1]) {
int temp = a[j];
a[j] = a[j + 1];
a[j + 1] = temp;
}
}
}
for (int i = 0; i < 3; i++) {
printf("%d ", a[i]);
}
printf("\n");

return 0;
}

abc是人为定值
