int main()

{

int number;

char c;

printf("Hello my name is computer\n");

// Number convertion

printf("Enter a number : ");

scanf("%d", &number);

int result = number * 123;

printf("The given number : %d, The product is : %d\n", number, result);

printf("Enter a character : ");

// Character convertion

scanf("\n%c", &c);

char upper = toupper(c);

char lower = tolower(c);

printf("The upper case is : %c, The lower case is : %c\n", upper, lower);

return 0;
