Explain the need of header files in cin and cout 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.
Explain the need of header files in cin and cout
- In C++, the reserved word “cin” is used to get inputs from the user.
- An object of “istream” class is the “cin” and it gets the input from the input device like keyboard.
- To get the input, “cin” uses the operator “>>” and it is called extraction operator.
- The reserved word “cout” is used to print outputs in the console output screen.
- An object of “ostream” class is the “cout” and it gives the result on the output device.
- To print the output, “cout” uses the operator “<<”, and it is called insertion operator.
