Carefully study the program below and show the precise output it would produce.
#include <cstdio> void drawChr(char c, int times); void update(int &s, int &m); int main() { int rows = 15; int side = 0; int middle = rows/2; while (middle > 2) { drawChr('.', side); drawChr('#', middle); drawChr('.', side); update(side, middle); printf("\n"); } for (int i = 0; i < 3; i++) { drawChr('.', side); drawChr('#', middle); drawChr('.', side); printf("\n"); } drawChr('#', side+middle+side); printf("\n"); } void drawChr(char c, int times) { for (int i = 0; i < times; i++) { printf("%c", c); } } void update(int &s, int &m) { s++; m = m - 2; }
