Char数组分为3个整数变量

Question

字符数组：

char inData[] = "1,13,1" 

或

char inData[] = "1,9,127"

如何从中提取数据为3个整数变量。分隔符是“，”。语言C ++。

Answer 1

使用sscanf

int a, b, c;
if (sscanf(inData, "%d,%d,%d", &a, &b, &c) == 3)
{
   // Got all three numbers converted, go ahead and use them.
}

Answer 2

#include <iostream>
#include <sstream>

using namespace std;

int main()
{
    char inData[] = "1,13,1";
    istringstream inDataStream(inData);

    int a, b, c;
    char x;
    inDataStream >> a >> x >> b >> x >> c;

    cout << a << ", " << b << ", " << c << endl;

    return 0;
}
