I have a 2D vector in which i want to use a character key to find a value. For example,
Here is my vector type:
vector<pair<char, double>>
characters: a b c d
double: 1.1 2.1 7.1 1.3
each double coorelates with a character value. I want search the vector for a character and have it give me its corresponding double value. How can I do that using this vector type?
char key = 'a';
auto find_it = find_if(myvec.begin(), myvec.end(), [key](const pair<char, double>& x) { return x.first == key; });
double value;
if (find_it != myvec.end())
{
value = find_it->second;
}
