静态2d数组初始化

Question

如何初始化静态2d数组

我试图通过statment初始化静态2d数组＆＃39; static int b [n] [m] = {}＆＃39; ，它显示错误，而在给出const参数时，它正在工作＆＃39; static int b [2] [10] = {}＆＃39;

#include<iostream>

using namespace std;

void a(int c, int n, int m){
static int b[n][m]={};
// static int b[2][10]={}; , here it is working fine
for(int i=0;i<n;i++){
    for(int j=0;j<m;j++){
        b[i][j] = i+j;
    cout<<b[i][j]<<" ";
    }
}

}

int main(){

int c;
cin>>c;
a(c,2,10);
    cout<<endl;
return 0;
}

Answer 1

您已经将数组初始化为0。

如果您要初始化其他内容，请尝试此

static int ar [2] [3] = {{1,2,3}，{4,5,6}};
