programming help

[jlw0000]

I am a beginning student trying to work through homework. Can you please help me with this question:

define an array named PeopleTypes that can store a maximum of 50 interger values that will be entered at the keyboard. Enter a series of 1s 2s 3s and 4s into the array where a 1 represents an infant, a 2 represents a child, a 3 represents a teenager, and a 4 represents an adult. any other interger value should not be accepted as valid input, and data entry should stop when a negative value has been entered.
The program should count the number of each 1,2,3,4 in the array and output a list of how many infants, chidren, teenagers, adults there are.


I can't seem to put it all together, here is some of my work so far:

int main()
{

int i, peopletypes[50]; //declare array of int called peopleTypes with a limit [50]

for(i= 0; i < 50; i++) //for loop
{
cout << "Enter type for # " << i; // prints the request
cin >> peopletypes[i];
if (peopletypes[i] < 1 || peopletypes[i] > 4) // must be between 1 and 4

cout << "Your input must be between 1 and 4";


else if (peopletypes[i] < 0) // must not be negative
//quit and tally the totals


}

{

int Infants = 0;
int Children = 0;
int Teens = 0;
int Adults = 0;

for(i = 0; i < 50; i++){ // TAlly the Scores

if (peopletypes[i] = 1)
Infants = Infants + 1;

if (peopletypes[i] = 2)
Children = Children + 1;

if (peopletypes[i] = 3)
Teens = Teens + 1;

if (peopletypes[i] = 4)
Adults = Adults + 1;
}

cout << "Infants :" << Infants << endl;
cout << "Children :" << Children << endl;
cout << "Teens :" << Teens << endl;
cout << "Adults :" << Adults << endl;

int main()
{

int i, peopletypes[50]; //declare array of int called peopleTypes with a limit [50]

for(i= 0; i < 50; i++) //for loop
{
cout << "Enter type for # " << i; // prints the request
cin >> peopletypes[i];
if (peopletypes[i] < 1 || peopletypes[i] > 4){ // must be between 1 and 4

cout << "Your input must be between 1 and 4";
i--;
continue;//These two statements are to repeat entry for the cell
}


else if (peopletypes[i] < 0) // must not be negative
break; //This exits the loop


}

int Infants = 0;
int Children = 0;
int Teens = 0;
int Adults = 0;

for(i = 0; i < 50; i++){ // TAlly the Scores

if (peopletypes[i] = 1)
Infants = Infants + 1;

if (peopletypes[i] = 2)
Children = Children + 1;

if (peopletypes[i] = 3)
Teens = Teens + 1;

if (peopletypes[i] = 4)
Adults = Adults + 1;
}

cout << "Infants :" << Infants << endl;
cout << "Children :" << Children << endl;
cout << "Teens :" << Teens << endl;
cout << "Adults :" << Adults << endl;
}

Above is what I would do.

There are still two problems with the above solution:
1) What if something other than a number is entered? What if the user types "A", for instance? Try it. Not good. This needs to be handled.

2) If a negative value is entered, then there will be fewer than 50 valid entries in the array. Your second loop needs to account for this.

Don't forget the difference between == and = when writing if statements.
