The project containing the code has all the MSVS2008 default settings.
Consider the following code, in which I will familiarize myself with the various STL suggestions:
#include <vector>
#include <iostream>
#include <numeric>
using namespace std;
template <class T> void print(const vector<T>& l)
{
cout << endl << "PV Size of vector is " << l.size() << "\n[";
for(int i = 0; i < l.size(); i++)
{
cout<<l[i]<<",";
}
cout << "]\n";
}
int main()
{
vector<double> vec1(4, 2.0);
vector<double> vec2(4, 4.0);
double init = 0.0;
double summation = accumulate(vec1.begin(), vec1.end(), init);
cout<<"Summation = "<<summation<<", init is "<<init<<endl;
double ip = inner_product(vec1.begin(), vec1.end(), vec2.begin(), init);
cout<<"ip = "<<ip<<", init is "<<init<<endl;
int size = 6;
int seed_value = 2;
vector<int> vec3(size, seed_value);
vector<int> result(size);
partial_sum(vec3.begin(), vec3.end(), result.begin());
cout<<"The partial sum of vec3 is ";
print(vec3);
int sz = 10;
int value = 2;
vector<int> vec4(sz);
for(int it = 0; it < vec4.size(); it++){
vec4[it] = value;
value++;
}
vector<int> result2(vec4.size());
adjacent_difference(vec4.begin(), vec4.end(), result2.begin());
cout<<"Adjacent differenec of vec4 is ";
print(vec4);
return(0);
}
The first time I try to run this (under Windows 7, Visual Studio 2008), I get the following error:

However, after clicking on windows that tell me that my code did not compile / work correctly, when I debug the same code again without any code changes, the program works. Is there a reason the code will not compile / link / run the first time, but will work fine the next time?
