Posted By: Easy Tutor     Category: C++ Programming     Views: 4870

Write a program that read n integers and add them up and output the result.

First line of the file will contain the number of test cases. Subsequent lines will contain one test case on each line.

Each test case will start with an integer ‘n’ the number of elements to be added. It will be followed by ‘n’ integers in that line.

For each test case you are required to output the result of the addition of the ‘n’ numbers.

 # include <iostream.h>
 # include <fstream.h>
 # include <string.h>
 # include <stdlib.h>
 # include <conio.h>

 int main( )
       clrscr( );

       fstream File;


         cout<<"Unable to open the input file."<<endl;
         cout<<"Press any key to exit."<<endl;

         getch( );

       char Input[100]={NULL};


       int counter=atoi(Input);

       for(int count_1=0;count_1<counter;count_1++)


         char *Ptr=NULL;

         Ptr=strtok(Input," ");

         int n=atoi(Ptr);

         Ptr=strtok(NULL," ");

         long sum=atoi(Ptr);

         for(int count_2=1;count_2<n;count_2++)
           Ptr=strtok(NULL," ");



       File.close( );

       getch( );
       return 0;
