What is conditional operator in C?
The conditional operator is a single programming statement and can only perform one operation. The if-else statement is a block statement, you can group multiple statements using a parenthesis. The conditional operator can return a value and so can be used for performing assignment operations.
What is conditional operators in C with example?
age >= 18 – test condition that checks if input value is greater or equal to 18. printf("You can vote") – expression1 that is executed if condition is true. printf("You cannot vote") – expression2 that is executed if condition is false.
What are conditional operators explain?
What is a conditional statement in C?
What are conditional operators examples?
The conditional operator "&&" first evaluates whether its first operand (i.e., number % 2 == 0) is true and then evaluates whether its second operand (i.e., number % 4 == 0) is true. As both are true, the logical AND condition is true.
What is data type long in C?
Longer integers: long
The long data type stores integers like int , but gives a wider range of values at the cost of taking more memory. Long stores at least 32 bits, giving it a range of -2,147,483,648 to 2,147,483,647. Alternatively, use unsigned long for a range of 0 to 4,294,967,295.
What does a question mark mean in C++?
The question mark is the conditional operator. The code means that if f==r then 1 is returned, otherwise, return 0. The code could be rewritten as int qempty() { if(f==r) return 1; else return 0; }
How does comma operator work in C?
The comma operator in c comes with the lowest precedence in the C language. The comma operator is basically a binary operator that initially operates the first available operand, discards the obtained result from it, evaluates the operands present after this, and then returns the result/value accordingly.
What is question mark in C programming?
The question mark operator, ?:, is also found in C++. Some people call it the ternary operator because it is the only operator in C++ (and Java) that takes three operands. If you are not familiar with it, it’s works like an if-else, but combines operators.
How do you use nested if in python?
Example. #!/usr/bin/python var = 100 if var < 200: print “Expression value is less than 200” if var == 150: print “Which is 150” elif var == 100: print “Which is 100” elif var == 50: print “Which is 50” elif var < 50: print “Expression value is less than 50” else: print “Could not find true expression” print “Good bye! …
What is AC file data type?
In C we have used Files. To handle files, we use the pointer of type FILE. So the FILE is a datatype. This is called the Opaque datatype. So its implementation is hidden.
What is the size of char variable in Java?
char: The char data type is a single 16-bit Unicode character. It has a minimum value of ‘u0000’ (or 0) and a maximum value of ‘uffff’ (or 65,535 inclusive).
What a variable is?
A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item. Age, sex, business income and expenses, country of birth, capital expenditure, class grades, eye colour and vehicle type are examples of variables.
What is a string in C language?
In C programming, a string is a sequence of characters terminated with a null character . For example: char c[] = “c string”; When the compiler encounters a sequence of characters enclosed in the double quotation marks, it appends a null character at the end by default.
What is conditional operator in C?
The conditional operator is a single programming statement and can only perform one operation. The if-else statement is a block statement, you can group multiple statements using a parenthesis. The conditional operator can return a value and so can be used for performing assignment operations.
What is an expression C++?
Expression is the combination of the constants, variables, and operators which are arranged according to the syntax of C++ language and, after computation returns some values that may be a boolean, an integer, or any other data type of C++.
What is conditional statement in C++?
C++ has the following conditional statements: Use if to specify a block of code to be executed, if a specified condition is true. Use else to specify a block of code to be executed, if the same condition is false. Use else if to specify a new condition to test, if the first condition is false.
What is conditional operator C++?
The conditional operator (? 🙂 is a ternary operator (it takes three operands). The conditional operator works as follows: The first operand is implicitly converted to bool . It is evaluated and all side effects are completed before continuing.
What is Python def?
Python def keyword is used to define a function, it is placed before a function name that is provided by the user to create a user-defined function. In python, a function is a logical unit of code containing a sequence of statements indented under a name given using the “def” keyword.
How do you break a function in Python?
Example. #!/usr/bin/python for letter in ‘Python’: # First Example if letter == ‘h’: break print ‘Current Letter :’, letter var = 10 # Second Example while var > 0: print ‘Current variable value :’, var var = var -1 if var == 5: break print “Good bye!”
How can you create a file in C?
To create a file in a ‘C’ program following syntax is used, FILE *fp; fp = fopen (“file_name”, “mode”); In the above syntax, the file is a data structure which is defined in the standard library. fopen is a standard function which is used to open a file.
