@3145779708nb 我跟你情况类似,但只要这么写
int n, ans = 0;
scanf("%d", n);
while(n != 0){
ans = ans * 10 + n % 10;
n /= 10;
}
printf("%d", ans);

@3145779708nb 谁说只有一个前导零。

@3145779708nb 另外,你前导零只删一个干嘛,输入001,你不就成了10?

@Saint_ying_xtf scanf 难道不用 &

int n, ans = 0;
scanf("%d", &n);
while(n != 0){
ans = ans * 10 + n % 10;
n /= 10;
}
printf("%d", ans);
