[英]printing an array as a table in c++
So, I am trying to print an array Fi[rows][columns] in a table format of 11 rows and 11 columns.因此,我试图以 11 行和 11 列的表格格式打印数组Fi[rows][columns] 。 The code I am using is:
我正在使用的代码是:
for (int i = 0; i < rows ; i++){
for (int j=0; j< columns; j++)
std::cout << Fi[i][j]<<"\t";
std::cout << "\n";
}
And my problem is, that the element printed on Fi[0][10] is not the one that it's supposed to be.我的问题是,打印在 Fi[0][10] 上的元素不是它应该是的元素。 Actually, if I simply print out
实际上,如果我只是打印出来
std::cout<< Fi[0][10];
I get the correct value.我得到正确的值。 Can someone help me to figure out what I am doing wrong?
有人可以帮我弄清楚我做错了什么吗?
Are you looking for something like this?你在寻找这样的东西吗? I changed the part
std::cout << "\n";
我改变了部分
std::cout << "\n";
to std::cout << std::endl;
到
std::cout << std::endl;
#include <array>
int main() {
int rows = 4;
int columns = 5;
int my_array[rows][columns] = {{0,1,2,3,4},{5,6,7,8,9},{10,11,12,13,13},{14,15,16,17,18}};
for (int i = 0; i < rows ; i++){
for (int j=0; j< columns; j++)
std::cout << my_array[i][j]<<"\t";
std::cout << std::endl;
}
return 0;
}
With the output:使用 output:
0 1 2 3 4
5 6 7 8 9
10 11 12 13 13
14 15 16 17 18
using namespace std;
#include<iostream>
int main(){
int num[3][3],i=0,sum=0;
for(i=0;i<3;i++){
for(int j=0;j<3;j++){
cin>>num[i][j];
sum+=num[i][j];
}
}
for(i=0;i<3;i++){
for(int j=0;j<3;j++){
cout<<num[i][j]<<"\t";
}
cout<<endl;
}
cout<<sum<<endl;
return 0;
}
