101             14000
101             18000

102             20000

Explanation / Answer

#include <iostream>
#include <string.h>
#include <stdlib.h>
#include <stdio.h>
#include <iomanip> // For formatting using setw and endl

using namespace std;
#define INPUT_LENGTH 255

struct salesData{
int salesID;
double sales;
};

int main(int argc, char *argv[]) {
  
struct salesData sd[10];
int salesid;
double totalsales = 0;

FILE *fileNames = NULL;
char input[INPUT_LENGTH]; // a string for reading from a file
char *next;
  
fileNames = fopen("data.txt", "r" ); // Read file name from arguments
int iCount = 0;
cout<<"Sales ID"<<setw(25)<<"Total sales amount"<<endl;

// Check if file opens
if( NULL != fileNames ){

// Iterate on all lines in file
while( NULL != fgets( input, INPUT_LENGTH, fileNames ) ){

// Tokenizing the line and print the data
next = strtok(input, " ");
salesid = atoi(next);
cout<<sd[iCount].salesID;
if(iCount == 0){
sd[iCount].salesID = salesid;
cout<<sd[iCount].salesID;
}
if(sd[iCount].salesID != salesid){
cout<<sd[iCount].salesID << setw(25) << sd[iCount].sales << endl;
iCount++;
sd[iCount].salesID = salesid;
}
// Get tokens from string separated by space.
while (next != NULL)
{
next = strtok(NULL, " ");
sd[iCount].sales = sd[iCount].sales + atof(next);
}
}
fclose(fileNames);
}else{
cout<<"Unable to open the file";
}
  
return 0;
}
