Exercise 1.10

With a For loop programming, the number of all natural numbers from 50 to 100 is calculated. The program is then rewritten with a while loop.

Troubleshooting

The program written with for IS as follows:

1#include <iostream>2 using namespacestd;3 4 intMain ()5 {6     intsum =0;7      for(inti = -; I <= -; ++i)8Sum + =i;9cout <<"Sum of ~ inclusive is"Ten<< sum <<Endl; One     return 0; A}

The program written with while is as follows:

1#include <iostream>2 using namespacestd;3 4 intMain ()5 {6     intsum =0, val = -;7      while(val<= -)8     {9Sum + =Val;Ten++Val; One     } Acout <<"Sum of ~ inclusive is" -<< sum <<Endl; -     return 0; the}
