loop for entering numbers into array

[kkoeplin]

for the part where I'm entering 20 integers into the array that are greater than 0 and less than 100 i had to put i-- to make it so when i entered a number out of range it did not become part of the 20 integers. i was wondering if there is a better way to do this?

  #include <iostream>
#include <cctype>

using namespace std;
/********************PROTOTYPES**************************/
void getValues(int userVals[], const int number);

/***********************************************************/
int main(){
    int userVals[20];
    const int number = 20;
    
    getValues(userVals, number);
    
    
    return 0;
}

/**********************Functions************************/

void getValues(int userVals[], const int number){
    
    int i = 0;
    for (i = 0; i < number; ++i) {
        cout << "Enter 20 integer values greater then zero and less than 100 " << endl;
        cin >> userVals[i];
            if (userVals[i] < 0 || userVals[i] > 100 ){
                cout << "you have entered an invalid number" << endl;
                i--;
        }
        else
            continue;
        }
    
    cout << "You entered: ";
    for (i = 0; i <number; ++i) {
        cout << userVals[i] << " ";}
    
    }

You can use the while loop to validate the user's input.

For instance:

#include <iostream>

void inputArray(int num[], int sz);
void displayArray(int num[], int sz);

int main()
{

    const int MAXELEMENTS{ 20 };
    int num[MAXELEMENTS] = { 0 };

    inputArray(num, MAXELEMENTS);
    displayArray(num, MAXELEMENTS);


    return 0;
}

void inputArray(int num[], int sz)
{
    int inputCounter{ sz };

    for (int count = 0; count < sz; count++)
    {
	   std::cout << "Enter a number from 0 to 100.\n";
	   std::cin >> num[count];

	   while (num[count] < 0 || num[count] > 100)
	   {
		  std::cout << "The number " << num[count] << " is not between 0 and 100.\n";
		  std::cout << "Enter a number from 0 to 100.\n";
		  std::cin >> num[count];
	   }

	   inputCounter--;

	   std::cout << "You have " << inputCounter << " left\n";

    }
}

void displayArray(int num[], int sz)
{
    std::cout << "Displaying the numbers you inputted...\n";
    for (int count = 0; count < sz; count++)
	   std::cout << num[count] << std::endl;
}
