Question

又一次报错!!

#include<iostream>
#include<random>
using namespace std;
const char *a[11][11];
int main() {
    int i{ 0 }, j{ 0 };
    for (; i <= 10; i++) {
        for (; j <= 10; j++) {
            if (rand() % 10 > 2) {
                a[i][j] = '0';
            }
            else {
                a[i][j] = '?';
            }

        }
    }
    for (; i <= 10; i++) {
        for (; j <= 10; j++) {
            printf(a[i][j]);
        }
    }
}

Answer 1

代码如下：

#include<iostream>
#include<random>
using namespace std;

int main() {
    char a[11][11];
    int i,  j;
    for (i = 0; i <= 10; i++) {
        for (j = 0; j <= 10; j++) {
            if (rand() % 10 > 2) {
                a[i][j] = '0';
            }
            else {
                a[i][j] = '?';
            }
        }
    }

    for (i=0; i <= 10; i++) {
        for (j=0; j <= 10; j++) {
            printf("%c ", a[i][j]);
        }
        printf("\n");
    }
}
