Write a program to input a number and print the sum of the following series.
Program 7
s= 1/2 + 2/3 + 3/4 + 4/5 + 5/6 – using do-while
1 class series
2 {
3 public static void main()
4 {
5 float s=0.0f, i;
6 i=1;
7 do
8 {
9 s = s + i/(i+1);
10 i=i+1;
11 }
12 while(i<=5);
13 System.out.println("Result : "+s);
14 }
15 }
You will get the following output:
9.3.5 Interconversion between different types of Loops
Code always allows flexibility in choosing the type of loop. We select the loops according to the ease of logic of the
code. We can also convert any type of loop to another loop just by changing the place of the parts of the loops.
for (initialization; condition for testing; increment or
decrement)
{ // job performed by the body of the loop; }
initialization;
while (condition for testing)
{ // job performed by the body of the loop;
increment or decrement;
}
initialization;
do
{ // job performed by the body of the loop;
increment or decrement;
} while (condition for testing);
