Answer to Question #258399 in C++ for Stiff

Question

The user must enter a positive integer between 5 and 15. If this number is valid, the

user must also choose between a triangle (T or t) and a square (S or s). Display suitable

error messages if necessary; otherwise, the program must use an asterisk to draw a

triangle or a square of the chosen size and display. Use a Select Case structure to make

the decision. Display appropriate error messages where applicable.

Answer 1

#include <stdio.h>

void drawTriangle(int a); // todo implement
void drawSquare(int a);  // todo implement

int main(void) {
  int a;
  scanf("%d", &a);
  if (5 > a || a > 15) {
    printf(stderr, "Entered number is not in range(5, 15).");
    return 0;
  }
  char s;
  scanf("%c", &s);
  switch(s) {
    case 'T':
    case 't':
      drawTriangle(a);
      break;
    case 'S':
    case 's':
      drawSquare(a);
      break;
    default:
      printf("Invalid choice!");
      return 0;
  }
  return 0;
}
