      #A+B problem {

      { #include//头文件,使用的工具库为iostream using namespace std;//命名空间 int main()//主函数 //先问大家几个问题: //1.我们如何获取a与b//2.我们如何进行对a于b的运算? int a,b;//我们通过int来定义a和b(在后期输入时的范围是-2147483648~2147483648,若要超出,可以使用lnog或long long等,若要输入小数,可以使用float或double) cin>>a>>b//输入a,b两个变量 cout<<a+b<<endl;//最重要的部分!!!这里我们要对a和b进行运算,这时我们要使用运算符,运算符有很多,如:“*”乘法 “/”除法 “+”加法 “-”减法 “^”次方 “%”取余…… return 0;//可有可无 //总结:1.a与b通过int定义,且不同的类型变量有不同规定取值范围; //2.我们使用运算符进行两个变量的运算
