Hi everyone, I was a solving a problem of changing one vector in a way of removing all the elements of the vector that the other vector has. And unfortunately it doesn't work. Here is the code :
Code:
#include<iostream>
#include<vector>
#include<string>
using namespace std;
template <typename type>
void function(vector<type>&a,vector<type>&b){
for(int i=0;i<a.size();i++){
int k(0);
for(int j=0;j<b.size();j++){
if(a[i]==b[j])
k=1;
}
if(k==1){
for(int p(i);p<a.size()-1;p++){
a[p]=a[p+1];
}
a.resize(a.size()-1);
}
}
}
int main(){
int n;
cout<<"How many words ?";
cin>>n;
cin.ignore(1000,'\n');
vector<string>s(n);
for(int i=0;i<n;i++){
getline(cin,s[i]);
}
int b;
cout<<"How many words now?";
cin>>b;
cin.ignore(1000,'\n');
vector<string>j(b);
for(int u(0);u<b;u++){
getline(cin,j[u]);
}
function(s,j);
cout<<endl;
for(int i=0;i<s.size();i++){
cout<<s[i]<<endl;
}
return 0;
}
