[問題] 統計字串中各數字個數
比如說輸入 1014587
輸出就是
0 :1
1 :2
2 :0
以此類推
但目前問題是if似乎沒作用
麻煩幫忙解題..
#include <iostream>
#include <string>
using namespace std;
int main()
{
int i,n0=0,n1=0,n2=0,n3=0,n4=0,n5=0,n6=0,n7=0,n8=0,n9=0;
char str[80];
cin.getline(str, 80);
//cout<<strlen(str)<<"\n";
for(i=0;i<=strlen(str);i++)
{
if(str[i]==0)
{
n0=n0+1;
}
if(str[i]==1)
{
n1=n1+1;
}
if(str[i]==2)
{
n2=n2+1;
}
if(str[i]==3)
{
n3=n3+1;
}
if(str[i]==4)
{
n4=n4+1;
}
if(str[i]==5)
{
n5=n5+1;
}
if(str[i]==6)
{
n6=n6+1;
}
if(str[i]==7)
{
n7=n7+1;
}
if(str[i]==8)
}
n8=n8+1;
}
if(str[i]==9)
{
n9=n9+1;
}
}
cout<<"0 : "<<n0<<"\n";
cout<<"1 : "<<n1<<"\n";
cout<<"2 : "<<n2<<"\n";
cout<<"3 : "<<n3<<"\n";
cout<<"4 : "<<n4<<"\n";
cout<<"5 : "<<n5<<"\n";
cout<<"6 : "<<n6<<"\n";
cout<<"7 : "<<n7<<"\n";
cout<<"8 : "<<n8<<"\n";
cout<<"9 : "<<n9<<"\n";
system("pause");
