Question

I want to be able to get a line and split it to different types of variables (using standard c++ libraries). So this input line:

C 56 99.7 86.7 9000

Will “explode” by a space char to these variables in order:

Char
std:string
double
double
double

This is how I currently handle the given input:

#define MAX_LINE 200

char line[MAX_LINE];
cout << "Enter the line: ";
cin.getline (line,MAX_LINE);

Is there some special function like getline() i can use to separate the given input and assign these input to variables (with casting or similar)?

Answer 1

Use the >> operator to get what you want

#include <iostream>

int main()
{
    char c;
    double d;
    std::cin >> c >> d;

    std::cout << "The char was: " << c << ", the double was:" << d;    
}
