One line...parse error? New programmer needs help please!

[floofy]

Hi,

I am extremely new to programming and I'm taking a beginner's course right now. We were given a .cpp code to correct so that it will compile.

I've already fixed a couple errors but Dev-C++ still gives me "parse" in the compiler window on this specific line:

for int = 0; < howmany + i++;

I don't exactly want to post the entire code, but I'm not sure if that single line is sufficient...pa rse error is some sort of parenthesis error, I'm assuming? Can you see anything wrong with that one single line?

Thanks in advance.

Hey there,
I think this is more along the lines of what you need:

for(int i = 0; i < howmany; i++)
{
  // code to repeat howmany times
}

I hope this helps,
Motoma

Thanks for your input Motoma...but it's still not compiling for some reason!

This is what exists in the program...I fixed all that was wrong with it before...but it's still not working.

#include <iostream>

using namespace std;


int main()
{
    int howmany;      // How many values to sum.
    float sum = 0.0;  // The running sum.

    // Ask the user and get how many numbers to read.
    cout << "Enter how many numbers I will sum: ";
    cin >> howmany

    for(int i = 0; i < howmany; i++);
    {
        float value;  // The current value.

        // Read the ith number.
        cout << "Enter number: " ;
        cin >> value;

        // Increment the sum.
        sum += value;
    }

    // prompt the result
    cout << "The sum is: " << sum << endl;

    cout << "Thank you for using the summer!" << endl;

    return 0;  // 0 means program exited successfully.
}

}

Watch your semicolons

cin >> howmany
should be

cin >> howmany;

for(int i = 0; i < howmany; i++);
should probably be

for(int i = 0; i < howmany; i++) //without the ; at the end
