a lil help.. prog's done but wrong output
I have a hw prob here that im done coding w/.. i just get the wrong output about halfway and i know kind of wat it is but i cant fix it. my thought is im makin my function to complex.
http://cis.poly.edu/cs1124/Homework/hw01/hw01.html
thats the site that explains the hw prob and heres my code..
Code:
#include <vector>
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
struct Process //Structure will hold all process information from the procces file
{
//CHECK THESE TYPES!!!
int procId; // process ID ... 1000.. 1001 etc
string name; // holds the name of the process
int cpuTime; // Total CPU time needed for process
int timeBurst; // Burst for each process
};
//will gather contents from stream and enter them into a vector of structs
void fillVector(ifstream&, vector<Process>&);
//Processes the schedule and outputs as it creates the schedules.
void procSched(vector<Process>&);
//----------------------------------------------
int main()
{
vector<Process> proc; //Vector of process structs
ifstream ifs; // filestream for process text
ifs.open("process.txt"); // open file and check for error while opening
if (!ifs)
{
cerr << "Error opening 'process.txt' \n ";
exit(1); //exit if error is found
}
fillVector(ifs, proc); //fill the vector with information from the stream
procSched(proc); //output the scheduling as it is calculated
return 0;
}
//-----------------------------------------------
void fillVector(ifstream& inputFile, vector<Process>& procVec)
{
Process tempProc; //temporary variable to fill process vector
//Loop through the file checking for each struct member
while (inputFile >> tempProc.procId >> tempProc.name
>> tempProc.cpuTime >> tempProc.timeBurst)
{
procVec.push_back(tempProc); // fill the vector with each temp member
}
}
void procSched(vector<Process>& procVector)
{
// totProc is the total number of Proccess that need to run
//size_t totProc = procVector.size();
int time(0); //will print the time each process began
while (!procVector.empty()) // Continue to process until vector is empty
{
for (size_t j = 0; j < procVector.size(); j++) // Loop through the vecotr
{
//The time is decreased by each processes burst
procVector[j].cpuTime -= procVector[j].timeBurst;
if (procVector[j].cpuTime <= 0) // If time is below 0, the process is exhausted
{
//output the process information with 0 being the final time left
cout << time << ' ' << procVector[j].procId << ' '
<< procVector[j].name << ' '
<< "0" << endl;
//The time the next process begins is incremented by the burst
//of the process just completed
time += procVector[j].timeBurst;
//delete the element of the vector
//that no longer runs as a process
procVector.erase(procVector.begin() + j);
}
else // if its not 0 the process is ongoing
{
//output the process information
cout << time << ' ' << procVector[j].procId << ' '
<< procVector[j].name << ' '
<< procVector[j].cpuTime << endl;
//The time the next process begins is incremented by the burst
//of the process just completed
time += procVector[j].timeBurst;
}
}
}
}
I know the prob is in my last function.. i think im either deleting something 2 quick or displaying 2 late. something to that effect... if u think i can do this more effectively plz tell me.
