c++實現統計字串中各字元的個數

#include<iostream>#include<string>using namespace std;void tongji(char*,int);int main(){char a[100];cout<<"請輸入字串:";gets_s(a);int n=strlen(a);cout<<"輸出字串:"<<endl;cout<<a<<endl;tongji(a,n);system("pause");return 0;}void tongji(char s[],int s1){int num=0,str=0,space=0,other=0;for(int i=0;i<s1;i++){if((s[i]>='a'&&s[i]<='z')||(s[i]>='A'&&s[i]<='Z'))++str;else if(s[i]>='0'&&s[i]<='9')++num;else if(s[i]==' ')++space;else ++other;}cout<<"字母:"<<str<<endl;cout<<"數字:"<<num<<endl;cout<<"空格:"<<space<<endl;cout<<"其他字元:"<<other<<endl;}
