电子学会 C语言 2级 17 、统计数字字符个数
C++参考代码：
#include<iostream>
#include<cstdio>
#include<cstring>
using namespace std;
int main()
{
string s;
getline(cin, s);
int len,cnt = 0;
len=s.size();
for (int i = 0; i < len; i++)
{
if (s[i] >= '0' && s[i] <= '9')
{
cnt++;
}
}
cout << cnt;
return 0;
}
python3代码:
n = input()
c = 0
for i in n:
if i.isnumeric():
c += 1
print(c)
#include<iostream>
#include<cstdio>
#include<cstring>
using namespace std;
int main()
{
string s;
getline(cin, s);
int len,cnt = 0;
len=s.size();
for (int i = 0; i < len; i++)
{
if (s[i] >= '0' && s[i] <= '9')
{

}
}
cout << cnt;
return 0;
