My brain is hurting and cant think anymore tonight. It deals with arrays & loops. It's the first c++ class at my college so it must be easy for a lot of people.

must be done within 1hour and maybe a few mins xD because of a due date.

It's only 2 problems, will pay 50 fg per question(depending on simplicity for me to understand)

PM me if interested.

Plz thank you

Code
#include <iostream>
#include <cstdlib>

using namespace std;

int main()
{
int seed, r;
string friends[5];
cout << "Who Should I Text?" << endl;
cout << "Enter seed" <<endl;
cin >> seed;

srand(seed);
for(int i = 0; i < 5; i++)
{
cout << "Enter fried " << i << endl;
cin >> friends[i];
}

r = rand() % 5;

cout << "You should text: " << friends[r] << endl;
cout << "These other friends didn't make the cut:" << endl;
for(int i = 0; i < 5; i++)
{
if(i != r)
cout << friends[i] << endl;
}

return 0;
}


Happy?

And I was being shitty for no reason before, which is why I edited my statement. But you went ahead and quoted me and kept it there for the record. Oh well.

toupper() takes a character and makes it uppercase. I did it didn't matter if you entered upper or lowercase. Looks like its supposed to be doing input validation to ensure you only enter uppercase


Code
#include <iostream>
#include <cstdlib>

using namespace std;

int main()
{
string expected = "BDAACABACDBCDADCCBDA";
string actual = "";
char c;
int pass = 15;
int result = 0;
bool valid;

cout << "Driver's License Exam Grader" << endl;
for(int i = 1; i <= expected.length(); i++)
{

do
{
cout << "Enter your answer for question " << i << endl;
cin >> c;
valid = c == 'A' || c == 'B' || c == 'C' || c == 'D';

if(!valid)
{
cout << "Invalid input. Enter only: A, B, C, or D. Try again." << endl;
}
else
actual += c;

}while(!valid);


}

for(int i = 0; i < expected.length(); i++)
{


if(expected[i] == actual[i])
{
result++;

}
else
{
cout << "Answer " << i+1 << " is incorrect." << endl;
}

}

cout << "Results (minimum " <<pass << " correct to pass):" << endl;
cout << "You got " << result << " correct." << endl;
cout << "You missed " << expected.length() - result << "." << endl;
if(result >= pass)
cout << "You've passed." << endl;
else
cout << "You've failed." << endl;

return 0;
}
