没有错误，但是第二次输入后代码崩溃

如何解决没有错误，但是第二次输入后代码崩溃

我需要编写此程序来计算电影院在学校的利润。它最初是使用 cin编写的，但是随后我需要使用printf重写它。该代码有零个错误，在您输入成人票销售数量后，它只会崩溃。

 router.get('/',function (req,res,next) {
        async.parallel({
           item1: function (callback) {
            request1 = new Request('query',function(err,rowCount,rows) {
            if (err) {
                console.log(err);
            }
            });
            var category = []
              request1.on("row",columns => {
              var category_item = {};
              for (var name in columns) {
                category_item[name] = columns[name].value;
              }
              category.push(category_item);             
            });
            request1.on("doneInProc",(rowCount,more,rows) => {
               callback(null,category);
            });
            con.execSql(request1);
          },item2: function (callback) {
            request2 = new Request('query',function (err,rows) {
              if (err) {
                console.log(err);
              }
            });
          var category1 = [];
          request2.on("row",columns => {
            var category1_item = {};
            for (var name in columns) {
              category1_item[name] = columns[name].value;
            }
            category1.push(category1_item);
          });
          request2.on("doneInProc",rows) => {
             callback(null,category1);
          });
          con.execSql(request2);
         },},results) {
            res.end(JSON.stringify(results));
          });
     });

}`

解决方法

Scanf需要一个指向整数的指针，而不是整数本身，请尝试对其进行更改：

int AdultSales,ChildrenSales;

printf("How many adults attended? ");
scanf(" %d",&AdultSales);

printf("How many children attended? ");
scanf(" %d",&ChildrenSales);

您可以在此处看到函数参考：http://www.cplusplus.com/reference/cstdio/scanf/

,

我认为您想这样做是因为错误已得到纠正

#include <iostream>
#include <stdio.h>

using namespace std;

int main()
{ char movie[50];

printf("What is the name of the movie?");
scanf(" %s",movie);

int AdultSales,&AdultSales); //scanf(" %d",AdultSales);

printf("How many children attended? ");
scanf(" %d",&ChildrenSales); //scanf(" %d",ChildrenSales);

float GrossBoxOfficeProfit= ChildrenSales*9.25+AdultSales*11.25;
float AmountPaidToDistributer=GrossBoxOfficeProfit*0.8;
float NetBoxOfficeProfit=GrossBoxOfficeProfit-AmountPaidToDistributer;


printf("movie: %s",movie);
printf("\nAdult tickets sold: %d",AdultSales);
printf("\nChild ticket sold: %d",ChildrenSales);
printf("\nGross Box office profit: %f",GrossBoxOfficeProfit);
printf("\nNet Box office profit: %f",NetBoxOfficeProfit);
printf("\nAmount paid to distributer: %f",AmountPaidToDistributer);

return  0;
}

这部分是错误的

    //scanf("movie: %s",movie);
    //scanf("\nAdult tickets sold: %d",AdultSales);
    //scanf("\nChild tickest sold: %d",ChildrenSales);
    //scanf("\nGross Box office profit: $%f",GrossBoxOfficeProfit);
    //scanf("\nNet Box office proft: $%f",NetBoxOfficeProfit);
    //scanf("\nAmount paid to distributer: $%f",AmountPaidToDistributer);
