Answer on Question#37215 - Programming, C++

Write a program that reads integer numbers from a file (number of them is unknown). Then, your program should print

Maximum number.

Total of even numbers.

Average of all numbers.

How many of them greater than the average.

Solution.

#include <iostream>
#include <fstream>
using namespace std;
int main(int argc, char * argv[])
{
    char ch[]="45 65 45 78 98 9 8 78 9 8 s"; //Here you can connect a file
    //like this
    // ifstream in;
    // in.open("D:\\filename.txt")
    // char ch;
    // in.get(ch);
    char chArray[5];
    int max=0;
    double median=0;
    int evennumbers=0,moreMedn=0;
    int count=0;
    int i=0,j=-1;
    int inum;
    while(1)
    {
        j++;i=0;
        while(ch[j]!=' ')
        {
            chArray[i]=ch[j];
            if(ch[j]==115){break;}
            j++; i++;
        }
        if(ch[j]==115){break;}
        inum = atoi(chArray);
        memset(chArray,0,5);
        if(inum>max){max=inum;}
        if (inum%2 == 0) {evennumbers++; }
        median += inum;
        count++;
    }
    median = median / count;
    j = -1;
    while (1)
    {
        j++; i = 0;
        while (ch[j] != ' ')
        {
            chArray[i] = ch[j];
            if (ch[j] == 115) {break;}
            j++; i++;
        }
        if (ch[j] == 115) {break;}
        inum = atoi(chArray);
        memset(chArray, 0, 5);
        if (inum > median) {moreMedn++; }
    }
    cout << max << endl;
    cout << evennumbers << endl;
    cout << median << endl;
    cout << moreMedn << endl;
    system("pause");
    return 0;
