I am writing a program in C++ to display a 2 dimensional array and then rotate it 90, 180, and 270 degrees. The array is a capital 'E' made of E's and blanks. I have written the program but when I run it it does print the E's rotated but vertically (top to bottom), my professor wants them rotated but to print horizontally (left to right).

By my logic I would have to edit my code to do:

-> print array row 1

-> rotate90

-> print array row 1

-> rotate90 (to revert to original)

-> rotate180

-> print array row 1

-> rotate180 (original)

-> rotate270

-> print array row 1

-> rotate 270 (original) ->

...continue 7 times until all rows are printed.

I know there is an easier way but I can't wrap my head around how to do it.

#include <iostream>



using namespace std;



char eArray[7]{

    {'E','E','E','E','E','E','E'},

    {'E',' ',' ',' ',' ',' ',' '},

    {'E',' ',' ',' ',' ',' ',' '},

    {'E','E','E','E','E',' ',' '},

    {'E',' ',' ',' ',' ',' ',' '},

    {'E',' ',' ',' ',' ',' ',' '},

    {'E','E','E','E','E','E','E'},

};

int n = 7;



void rotateArray90(char a[7]){



for (int i = 0; i < n; i += 1) {

  for (int j = i+1; j < n; j += 1) {

    swap(eArray[i][j], eArray[j][i]);

}}}



void flipArray180(char a[7]){



for (int i = 0; i < n; i += 1) {

  for (int j = 0; j < n/2; j += 1) {

    swap(eArray[i][j], eArray[i][n-1-j]);

}}}



void rotateArray270(char a[7]){



for (int i = 0; i < n; i += 1) {

  for (int j = 0; j < n/2; j += 1) {

    swap(eArray[i][j], eArray[n-1-i][j]);

}}}



void printArray(char a[7]){



for (int i = 0; i < n; ++i){

  for (int j = 0; j < n; ++j){

        cout << eArray[i][j] <<" ";

  }cout << endl;

}}



int main(){



printArray(eArray);

cout <<"n";



rotateArray90(eArray);

printArray(eArray);

cout <<"n";

rotateArray90(eArray);



flipArray180(eArray);

printArray(eArray);

cout <<"n";

flipArray180(eArray);



rotateArray270(eArray);

printArray(eArray);

cout <<"n";

rotateArray270(eArray);



}

Thank you for the help.
