C++算术运算符
试试下面的例子就明白了所有在C++中可用的算术运算符。
复制下面的C++程序并粘贴到test.cpp 文件编译并运行此程序。
#include <iostream> using namespace std; main() { int a = 21; int b = 10; int c ; c = a + b; cout << "Line 1 - Value of c is :" << c << endl ; c = a - b; cout << "Line 2 - Value of c is :" << c << endl ; c = a * b; cout << "Line 3 - Value of c is :" << c << endl ; c = a / b; cout << "Line 4 - Value of c is :" << c << endl ; c = a % b; cout << "Line 5 - Value of c is :" << c << endl ; c = a++; cout << "Line 6 - Value of c is :" << c << endl ; c = a--; cout << "Line 7 - Value of c is :" << c << endl ; return 0; }
让我们编译和运行上面的程序,这将产生以下结果:
Line 1 - Value of c is :31 Line 2 - Value of c is :11 Line 3 - Value of c is :210 Line 4 - Value of c is :2 Line 5 - Value of c is :1 Line 6 - Value of c is :21 Line 7 - Value of c is :22
