看看我的代码,它作为一只乌龟运行缓慢,我在第四代i7下运行它...而且显示结果真的很慢.有没有人有一个想法？或者这应该是一个非常缓慢的执行!？

PS:脚本的目的是找到相同方向的四个相邻数字的最大乘积,实际上在这个代码中我只是寻找上一个

我开始用C++学习递归,我遇到了一个我无法弄清楚的问题.

发生的事情是Eclipse和g ++说我的变量类型与函数声明不匹配,但我相信它确实如此.

请看一下,首先在Eclipse的屏幕转储中显示错误:

还有文本而不是图形形式的代码:

int saida(char **matriz, char dir,int entrada_l, int entrada_c,int* zeros,int** tracker) {

    int flag3,flag4,tamanho_martiz = 8;

    int resp;
    if(dir == 'c'){
        if(matriz[entrada_l++][entrada_c] == '0'){
            resp = saida(matriz, 'c',entrada_l,entrada_c,&zeros,tracker);
        }
    }

    return 0;
