So I just started C++ and have been reading through notes and working on tasks given to me by my lecturer. I have came across a few things I can't figure out.
1. Removing decimal places on a float number if it comes out as whole number.
Say average turns out to be 6, it will display as 6.00. I want to remove the decimal points so it displays as 6. But if it comes out like 6.53, I want to keep it like that.Code:sum = firstNumber + secondNumber + thirdNumber; average = static_cast<float>(sum)/3; cout.precision(2); cout << "The average is: " << fixed << average << endl;
2. Displaying the £ sign in C++. If I do,
It will display something like "ủ".Code:cout << "£";
3. Using strings in loops.
When this code is executed it works fine the first time, when I press Y for more employees, it completely skips getline(cin,name);.Code:#include <iostream> #include <string> using namespace std; void main() { float hours, salary, rateOfPay; char reply; string name; do { cout << "Please enter the name: "; getline(cin,name); cout << "Please enter the rate of pay: "; cin >> rateOfPay; cout << "Please enter the amount of hours worked: "; cin >> hours; salary = rateOfPay * hours; cout.precision(2); cout << "The salary is: " << fixed << salary << endl; cout << "Do you have any more employees? "; cin >> reply; } while (reply !='N'); }
My code when ran looks something like this.
Please enter the name: Jim Murray
Please enter the rate of pay: 10
Please enter the amount of hours worked: 10
The salary is: 100.00
Do you have any more employess? Y
Please enter the name: Please enter the rate of pay: 10
Please enter the amount of hours worked: 10
The salary is: 100
Do you have anymore employees? N
