你好，我想从用户那里得到输入。用户何时输入-1号，我想打破这个循环。但是我收到一些错误代码：““ HelloC.exe中0x53918F0E（ucrtbased.dll）的未处理异常：0xC0000005：访问冲突写入位置0xCCCCCCCC。”

我的错在哪里？当我尝试将函数类型从void更改为int时，得到相同的错误。

Answer 1

问题很少，首先是这个

scanf("%d", param[i]);

应该是

scanf("%d", &param[i]); /* need to provide address */

buildArray()原型也应该

void buildArray(int *);

代替

void buildArray();

同样do..while条件错误，请在循环的条件部分中使用param[i-1]代替param[i]。

示例代码

void buildArray(int param[]) {
        int i = 0;
        do {
                printf("Please enter number :");
                scanf("%d", &param[i]);
                printf("entered : %d\n", param[i]);
                i++; /* because of this, condition part should be param[i-1] != -1 */

        }while(param[i-1] != -1); /* it should be param[i-1] */
}
