Converting a string into multiple ints

Question

Newbie question but I have a string that gets 3 numbers, such as:

144.3 432.3 532.3

Now I define 3 floats with

float x;
float y;
float z;

How can I put all the values inside of them? Where,

x = 144.3; 
y = 432.3; 
z = 532.3;

You can use std::stringstream:

std::stringstream ss("144.3 432.3 532.3");
float x, y, z;
ss >> x >> y >> z;

Try the stof standard library function.

std::string orbits ("686.97 365.24");
std::string::size_type sz;     // alias of size_t

float mars = std::stof (orbits,&sz);
float earth = std::stof (orbits.substr(sz));
