Multiplication Table in C

Displaying table up to 10

#include <stdio.h>
int main() {
    int num, i = 1;
    printf("
    Enter any Number:");
    scanf("%d", &num);
    printf("Multiplication table of %d: ", num);
    while (i <= 10) {
        printf("
        %d x %d = %d", num, i, num * i);
        i++;  }
    return 0;
}

Output:

Enter any Number: 5
5 x 1 = 5
5 x 2 = 10
5 x 3 = 15
5 x 4 = 20
5 x 5 = 25
5 x 6 = 30
5 x 7 = 35
5 x 8 = 40
5 x 9 = 45
5 x 10 = 50

Displaying multiplication table up to n numbers:

#include <stdio.h>
int main() {
  int n, i, range;
  printf("Enter an integer: ");
  scanf("%d", &n);
  // prompt user for positive range
  do {
    printf("Enter the range (positive integer): ");
    scanf("%d", &range);
  } while (range <= 0);
  for (i = 1; i <= range; ++i) {
    printf("%d * %d = %d \n", n, i, n * i);
  }
  return 0;
}

Output:

Enter an integer: 12
Enter the range (positive integer): -8
Enter the range (positive integer): 8
12 * 1 = 12 
12 * 2 = 24 
12 * 3 = 36 
12 * 4 = 48 
12 * 5 = 60 
12 * 6 = 72 
12 * 7 = 84 
12 * 8 = 96
