Question

Implement a function called rightrotate(int src[4][4], int dst[4][4]) that rotates the values in the src array 90 degrees to the left and stores it in the dst array. (See example below). Save your program in a file called Q4.cpp and save it in Question #4. YOU MUST USE LOOPS FOR THIS QUESTION!

src

1,2,3,4

5,6,7,8

9,0,1,2

3,4,5,6

dst

4,8,2,6

3,7,1,5

2,6,0,4

1,5,9,3

Answer 1

#include <iostream> #include <cmath> using namespace std; void rightrotate( int scr[][4] , int dist[4][4]){ for (int i = 0; i < 4; ++i) { for (int j = 0; j < 4; ++j) { dist[i][j] = scr[j][4-i-1]; } } } void print_arr(int dist[4][4] ) { for (int i = 0; i < 4; ++i) { for (int j = 0; j < 4; ++j) { cout << dist[i][j] << " "; } cout << endl; } } int main() { int scr[4][4]= { 1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6}; int dist[4][4]; rightrotate( scr, dist ); print_arr(dist); }
