#include<bits/stdc++.h> using namespace std; string n; long sum=0; int main(){ getline(cin,n); for(int i=0;n[i];i++){ if(n[i]>='0'&&n[i]<='9') sum++; } cout<<sum; return 0; }字符串？完全没用过

#include<iostream> using namespace std; int main() { char a; int sum=0; while(cin>>a) { if(a>='0'&&a<='9') { sum++; } } cout<<sum; return 0; }字符串？数组？没用过

强转yyds😄
#include <bits/stdc++.h> using namespace std; int main(int argc, char **argv){ char c; int cnt = 0; while (cin >> c){ if ((int) c >= '0' && (int) c <= '0' + 9){ cnt++; } } cout << cnt; return 0; } -

我喜欢复制粘贴
#include <string> using namespace std; int main() { string a; int sum=0; getline (cin,a); for (int i=0;i<a.length();i++){ if (a[i]=='1' || a[i]=='2' || a[i]=='3' || a[i]=='4' || a[i]=='5' || a[i]=='6' || a[i]=='7' || a[i]=='8' || a[i]=='9' || a[i]=='0' ) { sum++; } } cout << sum; } -

只有60分qwq
#include<iostream> #include<cstdio> #include<cstring> using namespace std; char c[255]; int len,sum; int main() { gets(c);//输入字符串 for(int i=0;i<255;++i) { if((int)(c[i])/*非0为真*/)///强转计算长度（因为不会用strlen） len++; } for(int i=0;i<len;++i) { if(c[i]>='0'&&c[i]<='9')//计算数字个数 sum++; } cout<<sum; return 0;//OK！ }
