I'm learning C and have a few questions. This program should take inputs for the name and price of items and output them to a text file. When the sentinel value 999 is entered for the item name, the while loop should cease and output all sets of inputs (item name and price) to the text file. C break and continue Statement In this article, you'll learn about C statements: break and continue. More specifically, what are they, when to use them and how to use them efficiently. I have a question about Pre-processor directives in c: For example: #ifndef QUESTION //some code here #ifndef QUESTION //some code here #endif #endif Can we use it in this way, and can the C compiler match the ifndef and endif in the right way? C Nested if.else The if.else statement executes two different codes depending upon whether the test expression is true or false. Sometimes, a choice has to be made from more than 2 possibilities. The nested if.else statement allows you to check for multiple test expressions and execute different codes for more than two conditions.

In C++, the braces of an if or an else clause can contain another if statement. These are known as nestedif statements. The following NestedIf program shows an example of a nested if statement in use.

This program starts by asking for the user’s birth year. If the birth year is later than 2000, then the program outputs the string “You were born in the 21st century”.

In mathematically accurate terms, the year 2000 belongs to the 20th century, not the 21st.

If the birth year is not greater than 2000, then the program enters the else clause of the outer if statement. This clause starts by outputting the string “You were born in” before comparing the birth year to 1950.

If the birth year is less than 1950, then the program adds the first “the first half”. If the birth year is not less than 1950, then the else clause of the inner if statement is executed, which tacks on the phrase “the second half”. Finally, the program adds the concluding phrase “of the 20th century” to whatever has been output so far.

In practice, the output of the program appears as follows for three possible values for birth year. First, 2002 produces the following:

For example, 1956 generates the following:

Finally, the birth year of 1932 generates the third possibility:

You could use a nested if to avoid the unnecessary comparisons in the NestedBranchDemo program:

/precision-tune-auto-care-technician-certifications.html. This version performs the first comparison just as before. If nOperand1 is greater than nOperand2, this snippet outputs the string “Argument 1 is greater than argument 2”. From here, however, control jumps to the final closed brace, thereby skipping the remaining comparisons.

If nOperand1 is not greater than nOperand2, then the snippet performs a second test to differentiate the case that nOperand1 is less than nOperand2 from the case that they are equal in value.

The figure shows graphically the flow of control for the NestedBranchDemo program for the input of 5 and 10.

Performing the test for equality is unnecessary: If nOperand1 is neither greater than nor less than nOperand2, then it must be equal.

If is a keyword in C++ language. It is used to execute or ignore a set of statements after testing it.

10. {
11. cout<<num<<' is a ONE digit Number ';
12. }
13. else if(num<100)
14. {
15. cout<<num<<' is a TWO digit Number ';
