小编use*_*390的帖子

每当我运行我的代码时，变量 bookcost 都会改变自己的值： 3435973836 。

它在到达 processingData 函数后执行此操作。我不知道为什么它一直这样做！我已经编写了这个没有函数的程序，它运行良好:( 这是我的第二节编程课，它是在线的，几乎没有教授的支持。

#include <stdio.h>

void inputData(int* inputs,int* booknmbr, int* nmbrpurchased, int* bookcost);
void processingData(int bookcost, int nmbrpurchased, int totalpurch, int costaccu);
void outputInfo(int booknmbr, int nmbrpurchased, int bookcost, int* total);

    int bookcounter = 0;
    int totalpurch = 0;
    int costaccu = 0;
    int totalcostaccu = 0;


int main ()

{
    int booknmbr;
    int nmbrpurchased;
    int bookcost; 
    int bookcounter = 0;
    int cycleRun;
    int total;
    int inputs;

    printf("Run Program? 1 for Yes or -1 …

#define SIZE 5

void inputData();
void processingData(int costs[]);
int costs[5];

int main ()
{
    inputData();
    processingData(costs);
}

void inputData()
{
    int i = 0;
    printf( "\nPlease enter five products costs.\n" );
    while(i < 5)
    {
       scanf("%d", &costs[i]);
       i = i + 1;
    }
    printf("stuff");
    for (i = 0, i < 5, i++)
        printf("%d\n", costs[i]);
}
