I am trying to make an array of all 32-255 ASCII characters, but I don't really think this is an array that I have created?
int main()
{
cout << " ASCII 32 - 255\n";
int col = 1;
for (int asc_char = 32; asc_char < 256; asc_char++)
{
cout << std::setw(6) << asc_char << setw(3) << static_cast<char>(asc_char);
col++;
if (col > 7)
{
col = 1;
}
cout << "\n";
return 0;
}
UPDATE:
This is how my code is now. The ASCII table comes out in an array, but not in 7 columns and 32 rows. The 32,33,34,35,36 before each character is also gone.
#include<iostream>
#include<iomanip>
using namespace std;
int main()
{
cout << " ASCII 32 - 255\n";
unsigned char myarray[7][32] = {};
int val = 32;
{
for (size_t i = 0; i < 7; i++) {
for (size_t j = 0; j < 32; j++) {
myarray[i][j] = val++;
}
}
}
// for (int asc_char = 32; asc_char < 256; asc_char++)
// cout << std::setw(6) << asc_char << setw(3) << static_cast<char>(asc_char);
for (auto& row : myarray) {
for (auto& col : row) {
std::cout << col << ' ';
}
std::cout << '\n';
}
return 0;
}
Referring to OP's comment:
How in earth can a make an array of 7 columns and 32 rows and fill it with the content of all 32-255 ASCII chars?
You can do that as follows:
#include <iostream>
#include <array>
int main() {
std::array<std::array<unsigned char,7>,32> myarray;
unsigned char val = 32;
for (auto& row : myarray) {
for (auto& col : row) {
col = val++;
}
}
}
Regarding to output the contents in a table, you probably want to use this:
for (auto& row : myarray) {
for (auto& col : row) {
std::cout << std::setw(6) << std::right << static_cast<int>(col)
<< std::setw(3) << std::right << static_cast<char>(col);
}
std::cout << std::endl;
}
Here's the fully working Live Demo
The output you'll get from the above looks like:
32 33 ! 34 " 35 # 36 $ 37 % 38 &
39 ' 40 ( 41 ) 42 * 43 + 44 , 45 -
46 . 47 / 48 0 49 1 50 2 51 3 52 4
53 5 54 6 55 7 56 8 57 9 58 : 59 ;
60 < 61 = 62 > 63 ? 64 @ 65 A 66 B

Note the � characters printed on the terminal for values grater than 126. These are depending on the code page chosen for displaying (e.g. special latin characters like í,ê,ü.ö,etc.).
