Describe how to use a for loop in a program.
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.
Describe how to use a for loop in a
for loop
- A for loop in a program defines a set of statements that can execute multiple times unless a given condition evaluates to false.
- It depicts the flow of execution (or control flow) in the program.
- The general format to use for loop in a program is given below:
for( initializationExpression; conditionalExpression; updatedExpression)
{
//statement(s);
}
- For example, to display a text message 10 times in a program, we need to write a statement once rather than 10 times and put that statement inside the for loop. The code segment in C++ is written below:
for (int index = 1; index <= 10; ++index) {
cout<<"Hello World!!!"; //output statement
}
