随机数程序 [英] random number program

问题描述

你好

    我正在编写一个非常简单的C ++程序来测试随机数调用，但是代码编译并运行它似乎并不能很好地工作......看看这段代码：

     i am writing a very simple C++ program to test random number recall but the code compiles and runs it just doesn't seem to work terribly well... have a look at this code:

// chunking.cpp : This file contains the 'main' function. Program execution begins and ends there.
//

#include "pch.h"
#include <iostream>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>

int main()
{
	int i, j, num;
	char s[80], s2[80];

	while (1) {
	 
	num = 0;
	for (i = 0; i < 10; i++) {
		j = (rand() * 10) / RAND_MAX;
		if (j == 10) --j;
		s[i] = j+'0';
	}
	s[i] = 0;
	printf("%s", s);
	getchar();
	for (j = 0; j < 100; j++)
		printf("\n");
    printf("Enter number: ");
	scanf_s("%79s", s2);
	if (!strcmp(s, s2))
		printf("Incorrect!\n");
 	else
 		printf("Correct!\n");
	getchar();

	}

}

希望你能提供帮助！

hope you can help!

推荐答案

首先查看编译器的所有警告并修复它们。



将警告级别设置为4通常也是一个好主意。

Start by looking at any and all warnings from the compiler and fixing them.

Setting Warning Level to 4 is also usually a good idea.
