如何使用for循环编写程序 [英] how to write a program using for loop

问题描述

编写一个程序，要求用户输入正整数N.然后程序在屏幕上显示N个星（每行一个星）。您需要使用for循环。

Write a program that asks the user for a positive integer N. The program then displays N stars on the screen (one star per line). You are required to use a for loop.

推荐答案

拿起一本书并学习编程的概念。

它会帮助你你尝试编写程序并学习编程。

Pick up a book and learn the concepts of programming.
It will help you as you try and write programs and learn about programming.

#include <iostream>
#include<conio.h>
#include<stdlib.h>
using namespace std;
int main()
{

    int N,i;
    system("cls");
    cout<<"enter the no of rows to be printed";
    cin>>N;
    for(i=1;i<=N;i++)
    {
        cout<<"*\n";
    }
    getch();
}

请注意，当您使用旧编译器时，只需替换#include< iostream>到#include< iostream.h>并删除使用命名空间std.Here我已经声明了两个变量N和i。变量N被声明并用于根据你的问题询问用户一个正整数。并且变量i用于执行for循环直到用户的条件满足。请注意转义序列\ n非常重要，因为它完全满足您的问题。

Kindly note that when you work on an old compiler just replace #include<iostream> to #include<iostream.h> and remove using namespace std.Here I have declared two variables N and i.The variable N is declared and used to ask the user for a positive integer as per your question.And the variable i is used in the execution of for loop till the user's condition satisfies.Please note the an escape sequence \n is very much important because it satisfies your question completely.
