思维导图
提示并输入一个字符串,统计该字符中大写、小写字母个数、数字个数、空格个数以及其他字符个数
#include <iostream>
using namespace std;
int main()
{
cout << "请输入一个字符串" << endl;
string str;
getline(cin,str);
int count[5]={0,0,0,0,-1};
int n=str.size();
cout << n << endl;
for(int i=0 ; i<= n ; i++)
{
if(str[i]>='A'&&str[i]<='Z')
{
count[0]++;
}
else if(str[i]>='a'&&str[i]<='z')
{
count[1]++;
}
else if(str[i]==' ')
{
count[2]++;
}
else if(str[i]>='0'&&str[i]<='9')
{
count[3]++;
}
else
{
count[4]++;
}
}
cout << "小写字母数量:" << count[0] << endl;
cout << "大写字母数量:" << count[1] << endl;
cout << "空格字符数量:" << count[2] << endl;
cout << "数字字符数量:" << count[3] << endl;
cout << "其他字符数量:" << count[4] << endl;
return 0;
