字符陣列被分成3個整數變量

Question

字符數組：

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

或

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

如何可以提取從他們的數據爲3名整數的變量。分隔符是「，」。語言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; 
}
