deleting an elemant of an array. plzzzz help !:((

[shaghayeghtavakoli]

I can't understand. this is a program to get an 10 characters including a-z, A-Z, and _ .
then this program will cout the text with out _ !
example:
cin >> sd_fd_e_dd
cout << sdfdedd

# include <iostream>
#include<vector>
using namespace std;

char a[10],m;
int main () {
    m=0; 
     for( int i=0;i<10;i++)
     cin>>a[i];
     for(int j=0;j<10;j++){
             if (a[j]>95&&a[j]<123&&a[j]>31&& a[j]<59){
             a.erase(a.begin() + j);
             }
     }
     for(int k= 0; k<(10-m)); k++)
     cout<< a[k];
    system ("pause");
}

how can I fix line 12 ?!

+ how can I totally write this program even in another way ?!

you could check if each element is a digit and if so copy it to another array and then output that new array.

Line 2: include is misspelled.

Line 12: You can't use erase on a simple char array.
