Question

create a c++ program with a function named display that displays 10 random words input by user using array. It should accept spaces and don’t accept numbers. If numbers were input it should say “INVALID INPUT”

Answer 1

#include <iostream>
#include <string>
#include <vector>

using namespace std;

int main()
{
	vector<string>vs(10);
	string tmp;
	bool isDig = false;
	cout << "Please enter 10 words:\n";
	for (int i = 0; i < 10; i++)
	{
		cout << "Enter " << i + 1 << " word: ";
		cin >> tmp;
		for (int j = 0; j < tmp.size(); j++)
		{
			if (isdigit(tmp[j]))
			{
				isDig = true;
				break;
			}
		}
		if (isDig == true)
		{
			cout << "INVALID INPUT";
			break;
		}
		vs.push_back(tmp);
	}


	if (isDig == false)
	{
		cout << "Entered words: ";
		vector<string>::iterator it;
		for (it = vs.begin(); it != vs.end(); it++)
		{
			cout << *it << " ";
		}
	}
}
