Question

Write a fragment of code that reads in integers from standard input, until end-of-file and sends their (floating point) average to standard output. If no numbers are input, the message "no values to average" is printed instead (while loops, end-of-file processing, mixed-mode arithmetic, basic conditional)

Answer 1

float number=-1;

float count=0;

float sum=0;

while(cin.eof()==false){

cin >> number;

sum += number;

count++;

}

if(number==-1){

cout << "no values to average";

}

else{

if (count>0)

cout << sum/count;

}
