Address the same problem in Example Problem 5.6 using the do - while

statement in C++.

Program Listing 5.8: Using the

do - while statement

1 #include <iostream.h>

2 #include <stdlib.h>

3 int main()

4 {

5 double conc, init_con,k;

6 int time;

7 init_con = 15.00;

8 k = 0.0567;

9 time =0;

10 cout<<»\nTIME(sec) CONC.(g mol/L)»;

11 do

12 {

13 conc = init_con - (k*time);

14 cout<<”\n “<<time<<”\t\t”<<conc;

15 time=time+10;

16 }while (time<70);

17 cout<<endl;

18 system(“pause”);

19 return 0;

20 }

Lines 11 to 16: Cover the do - while statement. Note that looping is done as

long as

time is less than 70. The ...
