Hi there,
I am looking for a warning in gcc that would warn me about
potentially dangerous operation, such as the one describe in (*). I
understand this is perfectly valid operation, but it looks to me like a
valid warning.
I tried the following so far:
-Wall -Wextra -Wconversion -Wsign-compare
Thanks
-Mathieu
(*)
#include <vector>
int main()
{
std::vector<int> v;
int s = 0;
for(unsigned int i = 0; i < v.size() - 1; ++i) // v.size() == 0
{
s += v[i] * v[i+1];
}
return 0;
}
