    \nGive the syntax of cout statement.
    \nAnswer:
    \nSyntax: cout<< expression or manipulator<\/p>\n

    Question 9.
    \nWhat is cascading in I\/O operations?
    \nAnswer:
    \nThe cascading is a way to extract\/insert multiple values from\/into more than one variable using one cin\/cout statement.<\/p>\n

    \"KSEEB<\/p>\n

    Question 10.
    \nHow is cascading useful in output operations?
    \nAnswer:
    \nThe cascading allows the user to use cout once only but use << operator several times to output many values.<\/p>\n

    1st PUC Computer Science Input Output Operators Five Marks Questions and Answers<\/h3>\n

    Question 1.
    \nDescribe I\/O operator.
    \nAnswer:
    \n1. Input Operator:
    \nThe statement cin>> num;
    \nis an input statement and causes the program to wait for the user to type in a number. The operator >>is known as extraction or get from the operator. It takes the value from the keyboard and assigns it to the variable on its right.<\/p>\n

    2. Output Operator:
    \nThe statement cout<< \u201c the numbers\u201d;
    \nuses the cout identifier that represents the standard output stream ( screen) in C++. The operator < – Sounds incomplete -Author.<\/p>\n

    Question 2.
    \nExplain manipulators.
    \nAnswer:
    \nA manipulator is a C++ is used to control the formatting of output and\/or input values. Manipulators can only be present in input\/output statements. The end1 manipulator causes a newline character to be output. end1 is defined in the <iostream> header file and can be used as long as the header file has been included.<\/p>\n

    Question 3.
    \nExplain input and output cascading with an example each.
    \nAnswer:
    \nThe multiple use of << or >>in a one statement is known for cascading.
    \nCascading of output operator ( >>):
    \ncout<<\u201c Hello \u201c<<\u201c ISC
    \ncout<< \u201cValue of B=\u201d<< b;
    \nCascading of input operator (>>):
    \nint n1,n2,n3;
    \ncin >> n1 >> n2 >> n3 ;
    \ncin>>n1>>n2;<\/p>\n","protected":false},"excerpt":{"rendered":"
