The following do...while loop rewritten as a for loop would be: int num = 5; do { System.out.print(num + " " ); num *= 3; //num = num * 3; } while (num <= 30); All of these are correct. int num = 5; for (num <= 30) { System.out.print(num + " "); num *= 3; } for (int num = 5; num <= 30) { System.out.print(num + " "); num *= 3; } for (int num = 5; num <= 30; num *= 3) { System.out.print(num + " " ); }
Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
The following do...while loop rewritten as a for loop would be:
int num = 5;
do {
System.out.print(num + " " );
num *= 3; //num = num * 3;
} while (num <= 30);

int num = 5; for (num <= 30) { System.out.print(num + " "); num *= 3; }
