这是一个示例,我测试了下面的代码以矩阵格式打印2D数组.您可以使用printf(%5d" ....)代替cout.%[n] d,其中n是相加那么多空格的整数.
This is an example, I tested the below code for printing a 2D array in matrix format. You can use printf("%5d"....) instead of cout. %[n]d, where n is the integer adding that many spaces.
while (!inFile.eof())
{
bad = false;
for (int i = 0; (i < MAX_ROWS) && !bad; i++) {
for (int j = 0; (j < MAX_COLUMNS) && !bad; j++) {
inFile >> ArrB[i][j];
if (ArrB[i][j] == -1) {
bad = true;
cout << "\nThe array does not have enough integers\n";
}
else {
if (ArrB[i][j] < 1) {
invalidnum = true;
}
}
if (!bad) {
printf("%3d",ArrB[i][j]);
//cout << *(*(ArrB + i) + j) << " ";
}
}
printf("\n");
}
输出:
1 2
3 4
5 6
The size of the array is correct.
1 2
3 7
5 8
The size of the array is correct.
-5 9
4
The array does not have enough integers
There is/are negative number(s) or zero(s) in the array imported from
your text file.
