3.2 赋值运算符

**作用：**用于将表达式的值赋给变量
赋值运算符包括以下几个符号：

示例：

#include<iostream>
using namespace std;
int main() {

	//赋值运算符

	// =
	int a = 10;
	a = 100;
	cout << "a = " << a << endl;

	// +=
	a = 10;
	a += 2; // a = a + 2;
	cout << "a = " << a << endl;

	// -=
	a = 10;
	a -= 2; // a = a - 2
	cout << "a = " << a << endl;

	// *=
	a = 10;
	a *= 2; // a = a * 2
	cout << "a = " << a << endl;

	// /=
	a = 10;
	a /= 2;  // a = a / 2;
	cout << "a = " << a << endl;

	// %=
	a = 10;
	a %= 2;  // a = a % 2;
	cout << "a = " << a << endl;

	system("pause");

	return 0;
}
/*
a = 100
a = 12
a = 8
a = 20
a = 5
a = 0
