hi,i am just a novice to cpp programming.
here is a simple program to store 25 floating-numbers using a vector and then output all the elements in the vector.
when i excute it , some problem arise and i don't know why
Could anyone tell me why???thx~~~
Code:// This program asks user to input 25 floating numbers and then output them #include<iostream> #include<string> #include<vector> using namespace std; int main(){ vector<float> v; int i=0; while(i<3){ cin >> v[i] ; i++; } cout << "\n"; cout << v[0] << endl; for(int j=0;j<v.size();j++){ cout << v[j] << endl; } return 0; }//
