Read 20 numbers and determine the highest and lowest

This exercise if very interesting, and has some tricks to work. RRecuerda
in programming in general, whether in C, C + +, Pascal, HTML, Java, PHP and other , the logic is an indispensable factor.

The title of the year are as follows:
Read 20 numbers and find the highest and lowest value of the readings.
For this exercise, I use a CYCLE FOR to read the 20 data that the user must enter, and within the same cycle, ANIDARÉ a couple of conditions to determine the highest and lowest number of values \u200b\u200bthat are entered.

  # include \u0026lt;iostream.h>  
 
   int i, major, minor, a; 
 
   int main (void  ) 
 
 {court \u0026lt;\u0026lt;"Welcome \\ nPlease enter 20 numbers and the program will determine the highest and lowest "\u0026lt;\u0026lt;endl \u0026lt;\u0026lt;endl; 
 minor = 99999999; 
 higher = -999; 
   for (a = 1, a \u0026lt;= 20; a + +) {
 
 court \u0026lt;\u0026lt;"Enter number" \u0026lt;\u0026lt;endl; 
 cin>> i; 
   if (i> largest) {
 
 largest = i;} 
 
   if (i \u0026lt;low) {
 
 minor = i;} 
 
 
 
} court \u0026lt;\u0026lt;"The largest number entered is" \u0026lt;\u0026lt;largest \u0026lt;\u0026lt;endl; 
 court \u0026lt;\u0026lt;"The smaller number entered is "\u0026lt;\u0026lt;lowest \u0026lt;\u0026lt;endl; 
 system (" pause "); 
   return 0;} 
 

This exercise can be done certainly prettier, but hey, here's the trick to work:
►
At first, I declare the major and minor numbers with presets, the largest , a very "small" within the set of real numbers, and the lowest , on the contrary, a very " large "; all this, so that with each iteration of the loop, assuming that the user does not enter exorbitant figures, both values \u200b\u200bare correctly allocated the largest and the child.
