Subsequent addition in an array

Subsequent addition in an array

New D.I.C Head Joined: 6 May, 2008 Posts: 2	CODE #include <iostream> using namespace std; int main() { float tarray[10] = [5 2 6 8 6 1 2 3 4 1]; int numberJ = 10 cout <<"arrival rates: "<<endl; for (int i = 0; i<=numberJ; i++ ) { float A[i]; sum = sum + tarray[i]; A[i] = sum; cout<<A[i]<<endl; } return 0; } This is a portion of code extracted from a larger body. The tarray is a set of inter-arrival times. I need to add a term to the previous sum of all terms, recording each result in another array. I called this array, A. The process is as follows: tarray = [5 2 6 8 6 1 2 3 4 1] add as explained above, record result: 5 + 2 = 7 7 + 6 = 13 13 + 8 = 21 21 + 6 = 27 and so on Obtain new array: A = [7 13 21 27....] Thanks for any help!

You pretty much nailed it... I made a few minor changes, and remarked them all (I think)... Using DEV C++ 4.9.9.2 it compiles and runs...

cpp

#include <iostream> 

using namespace std; 

int main() 
{ 
int A[10];  // moved this up here
int tarray[10] = {5,6,8,6,1,2,3,4,1}; //braces not brackets, add comma's
int numberJ = 10;    // need semicolon
int sum=0;   // need to initlize sum
cout <<"arrival rates: "<<endl;
    for (int i = 0; i<=numberJ; i++ ){
//      float A[i];
      sum = sum + tarray[i];
      A[i] = sum;
      cout<<i<<". = "<<A[i]<<endl;
    }  
    system("pause"); // my own preference
return 0; 
}
