为什么int count=1显示missing';'before 'type'
时间: 2023-12-03 20:03:20 浏览: 71
在C++中,变量声明需要指定变量的类型。在这种情况下,编译器可能会将"count"解释为"类型",而不是变量名。因此,它会提示错误消息"missing ';' before 'type'",表示在声明变量之前需要添加分号。要解决这个问题,您可以将变量类型与变量名放在一起,并用分号结尾,如下所示:
```
int count = 1;
```

int count = 1;
```
n = int(input()) count = 0 for i in range(1, n+1): count += str(i).count('2') print(count)
There are a few issues with this code:
1. The second line is missing a colon after the variable declaration.
2. The loop should start at 1 and end at n+1 to include n.
3. The variable count should be initialized to 0 before the loop.
4. The indentation for the third line should be inside the loop.
5. The print statement should be outside the loop and should print the total count, not the count for each iteration.
Here's the corrected code:
n = int(input())
count = 0
for i in range(1, n+1):
count += str(i).count('2')
print(count)
