Need help on for loop and array

How can I change this code so it will output for two or more values in an array like vec[vSize]={5000,3000,4000}; instead of one value so in this case I would get three outputs for each timing of the for loop?

Code:

---


#include< iostream >
#include< iomanip >
#include< cstdlib >
#include< ctime >
#include< cstdio >
#include< fstream >

const int vSize = 1;
using namespace std;



int main()
{
 
    int vec[vSize]={5000};//,50000//,100000,200000,400000};

    //Declare the clock variables
    clock_t start,finish;
    clock_t startAll;

    //Declare and initialize all the variables
  double duration;
   
    //Declare the streams and the input and output files
    ifstream inFile;
  ofstream outFile;

    inFile.open("input1.txt");
  outFile.open("A:/output1.txt");

   
int Sum=0;
   
   
   
    for (int iterationcountselector = 0; iterationcountselector < vSize; ++iterationcountselector)
    {
        start=clock();
        for(int i =0; i < vSize ; i++)
        {
              Sum++;
              outFile<< Sum<<endl;
        }
    }

    /*    finish=clock();
        duration=(double)(finish-start)/CLOCKS_PER_SEC;
        cout<<"          "<< setw(4)<< duration;*/
       
   
          finish=clock();
        duration=(double)(finish-start)/CLOCKS_PER_SEC;
        cout<<"Total Time Duration"<< duration<<" ms"<< endl;

   
   
    for (iterationcountselector = 0; iterationcountselector < vSize; ++iterationcountselector)
    {
       
   
          for(int i =0; i < vSize; i++)
        {
              Sum++;
              outFile<< Sum<<endl;
        }
    }

        finish=clock();
        duration=(double)(finish-start)/CLOCKS_PER_SEC;
        cout<<"Total Time Duration"<< duration<<" ms"<< endl;
   
    return 0;
}//end of main

Im not sure exactly what you mean, but here is an example of how to print a whole line of array elements then go to the next line and print the second set of array elements.

Code:

---

for (x=0;x<10;x++)
{
        for(y=0;y<10;y++)
        {
                cout << y << " ";
        }
        cout << "." << endl;
}

output:
1 2 3 4 5 6 7 8 9 10.
1 2 3 4 5 6 7 8 9 10.

instead of
1
2
3
4
etc....

I am trying to time a for loop for different values in a array. My output is the amount of time the for loop runs for an array value.

You changed your inner loop from your last post. You want to compare i to the current value of the vec array, as indexed by the outer loop. So change your inner loop to check for i < vec[iterationcountselector]. Notice how the outer loop controls the inner loop when you use that value as the index.
