1，while语句while是一个条件循环语句写个例子，用while语句求1-10的整数和#include <iostream>int main(int argc, char **argv){ int sum=0, num=1; while(num<=10) { sum+=num; num++; } std::cout << "1+2+...+10=" << sum << std::endl; return 0;}

操作系统：ubuntu编辑器：vim编译器：g++先写一个简单的c++程序#include <iostream>int main(){ std::cout << "please enter two numbers:" << std::endl; int num1 = 0, num2 = 0; std::cin >> num1 >> num2; std::cout << num1 << " + " &lt
