flowgorithm chart for input 1 2 3 and print 1st 2nd 3rd

Question

I need to create a flowgorithm chart for user to input a number 1 2 or 3 and then the number prints 1st 2nd or 3rd (the 2 letter ending) How n the heck can i do this????

Answer 1

Well your chart would first prompt the user, then with the input, use a series of conditionals based on its last digit to add the two letter ending. Below is a code for how the algorithm can be made in C++. Use the comments to construct your Flow Chart. Based on the last digit, only a last digit of 1, 2, and 3 will warrant a different ending than "th" so we make if statements for those and the overall else statement will output "th".

int main()

{

// Prompt for number and save to a vairable

std::cout << "Input a number: ";

int number;

std::cin >> number;

// Determine last digit of inputed number

int last_digit = number % 10;

/*

Series of conditionals checking divisibility

...0 --> ...0th

...1 --> ...1st --> SPECIAL

...2 --> ...2nd --> SPECIAL

...3 --> ...3rd --> SPECIAL

...4 --> ...4th

...5 --> ...5th

...6 --> ...6th

...7 --> ...7th

...8 --> ...8th

...9 --> ...8th

*/

if (last_digit == 1) {

std::cout << number << "st" << endl;

} else if (last_digit == 2) {

std::cout << number << "nd" << endl;

} else if (last_digit == 3) {

std::cout << number << "rd" << endl;

} else {

std::cout << number << "th" << endl;

}

return 0;

}
