C++ 内联函数(十一)--inline对比C宏

#include <iostream>//C宏#define k_squgec(X) (X)*(X)#define k_squgec2(X) X*X//C++ 内联函数inline double SQUGEC(double X) {return X*X;}int main(int argc, const char * argv[]) {        int a, b ,c = 12;        //非正常宏传值    a = k_squgec2(10+20); //230 理解为10*20+10+20，好怪的运算,用括号(X)*(X)可以//    a = k_squgec2(c++); //语法警告        //等值    a = k_squgec(10+20);    b = SQUGEC(10+20);        a = k_squgec2(c); //12*12    a = k_squgec(c); //12*12    b = SQUGEC(10+2);            return 0;}
