### C ++代码来演示abort()函数的示例 **(**C++ code to demonstrate the example of abort() function**)** ###

// C++ code to demonstrate the example of
    // abort() function
    
    #include <iostream>
    #include <cstdlib>
    using namespace std;
    
    // main() section
    int main()
    {
    
        float x, y;
        float result;
    
        while (1) {
            cout << "Input the value of x: ";
            cin >> x;
            cout << "Input the value of y: ";
            cin >> y;
            
            if (y == 0) {
                cout << "Value of Y cannot be 0" << endl;
                abort();
            }
            
            result = (float)x / (float)y;
            cout << x << "/" << y << ": " << x / y << endl;
        }
        
        return 0;
    }

**Output**

**输出量**

Input the value of x: 10
    Input the value of y: 2 
    10/2: 5 
    Input the value of x: 10
    Input the value of y: 3 
    10/3: 3.33333 
    Input the value of x: 5 
    Input the value of y: 3 
    5/3: 1.66667
    Input the value of x: 6 
    Input the value of y: 0 
    Value of Y cannot be 0
    Aborted (core dumped)
