字符串字符个数统计解决方法

字符串字符个数统计
#include<iostream>
using namespace std;
void main()
{
char ch,str1[30];
int i = 0,j =0, len,value = 0;
cout << "input the string:" << endl;
cin >> str1;
len = strlen(str1);
ch = str1[i];
while(ch != '\0')
{
while(j < len)
{
if(ch = str1[j])
value++;
j++;
}
cout << "the number of "<<ch<< "is:"<<value<<endl;
ch = str1[++i];
}
}


[解决办法]
看不懂，你在做啥？有啥问题？
[解决办法]

C/C++ code

#include<iostream>using namespace std;void main(){char ch,str1[30]={0};int i = 0,j =0, len,value = 0;cout << "input the string:" << endl;cin.getline(str1,30);len = strlen(str1);ch = str1[i];while(ch != '\0'){while(j < len){if(ch = str1[j])value++;j++;}cout << "the number of "<<ch<< "is:"<<value<<endl;ch = str1[++i];}}
