我输出的是”它是个3位的数!“,和题目一样啊 怎么回事呢,求大神解答。
int num = 999;
int count = 0;
if((num>=0) && (num<=999999999)){
while(num != 0){
count++;
num = num / 10;
}
System.out.println("它是个"+count+"位的数!");
}else{
System.out.println("输入有误");
}
int num = 999;
int count = 0;
if((num>=0) && (num<=999999999)){
while(num != 0){
count++;
num = num / 10;
}
System.out.println("它是个"+count+"位的数!");
}else{
System.out.println("输入有误");
}
