What should main() return in C and C++?
In C/C++, the main() function is used in the beginning of every program. This returns the program execution status in the operating system. Syntax Following is the syntax of the main() function using C/C++: int main(void); int main(int argc, char *argv[]); Example Below, the C/C++ example shows the usage of the main() return value. C C++ #include int main() { printf("Hello, C World!"); return 0; } Key Points of C Return 0: This is standard for successful execution Non-zero: It indicates error Implicit return: C99 allows omitting return #include int main() { std::cout
Read MoreConvert a C++ String to Upper Case
In C++, converting a string into uppercase means changing all the characters into uppercase. This is a common requirement in many applications, such as formatting output, standard data input, and case sensitivity. Following is the table that shows the conversion of string to uppercase: String Case Characters Uppercase Characters ...
Read MoreC++ Program to Convert Octal Number to Binary Number
In a computer system, the binary number is expressed in the binary numeral system while the octal number is in the octal numeral system. The binary number is in base 2 while the octal number is in base 8. Here, we provide the tabular data to understand binary numbers and their corresponding octal numbers as follows: Octal Number ...
Read MoreC++ Program to Implement Parallel Array
A parallel array is a structure that contains multiple arrays. Each of these arrays are of the same size and the array elements are related to each other. All the elements in a parallel array represent a common entity. Here, we provide the basic example to understand the parallel array in C++ − employee_name = { Harry, Sally, Mark, Frank, Judy } employee_salary = {10000, 5000, 20000, 12000, 5000} Here, The name and salary of 5 different employees is stored in two different arrays. Example of Parallel Arrays This is an implementation of a parallel array ...
Read MoreDifferent Types of Database Users
Database users interact with data to update, read, and modify the given information daily. There are various types of database users and we will learn in detail about them. Database users can be divided into the following types − Naive users / Parametric users Sophisticated users End Users Application Programmer or Specialized users or Back-End Developer System Analyst Database Administrator (DBA) Temporary Users or Casual Users These users can access the database and recover the data using various applications. Let’s have a quick understanding of all the types in detail − End Users/Parametric Users These users access the ...
Read MoreJava program to check whether the number is divisible by 5
In mathematics, the divisibility rule of 5 states that if the number ends with 0 or 5 then it will divisible by 5. There is another way to identify the divisibility rule of 5, if the remainder comes to 0 it returns the number is divisible by 5. The mod(%) operator is normally used in programming when it comes to divisibility. Following are some examples which helps you to understand the divibility rule of 5 − Given number is 525, the number ends with 5 and it is divisible by 5. Given number is 7050, the number ends with ...
Read MorePython - K difference index Pairing in List
The K is the special number that set the sum of the difference values starting with 0th index. For example, if k = 3 it means the 0th index added with K and finds the exact pairs. In Python, we have some built-in functions such as str(), len(), and append() will be used to solve the K difference index pairing in list. Let’s take an example of list. The given list, [“A”, “B”, “C”, “D”, “E”, “F”] Then the K value set to 1 The final output pair the index as [“AC”, “BD”, “CE”, ...
Read MoreCheck if the Sum of Digits of a Number N Divides It
The N number is the special number of integer type that calculates the individual digit of sum. So, this sum will be divisible by its own number. Let’s take an example of this. The given integer number, N = 36 The sum of each digit, 3 + 6 = 9 Therefore, 36 is successfully divisible by 9 and it verifies for N divides it. Algorithm The following steps are- Step 1: We will start the program by mentioning the header file iostream. Step 2: Common Matches:- Then used the function definition digit_sum() that accepts the parameter a variable n ...
Read MoreHow to Sort a Pandas DataFrame by Date?
Python’s Pandas DataFrame defines the two-dimensional structure that consists of rows and columns. The main feature of pandas is an easier way of handing the given data. In Python, we have some in-built functions such as to_datetime(), sorted(), lambda, and, sort_value() will be Sort a Pandas DataFrame by Date. Syntax The following syntax is used in the examples- to_datetime() The to_datetime() is an in-built function in Python that convert string dates into date-time objects. sorted() The built-in function sorted() of Python states that the list can be sort as specified iterable objects. lambda This lambda function in ...
Read MorePython - Filter Tuples with All Even Elements
The problem statement allows us to determine the position of the desired string in the list, which can be useful for various purposes, such as accessing or manipulating elements at that specific index. In Python, we have some built-in functions like reduce(), str(), filter(), lambda, and, all() that will be used to Find Index Containing String in List. Syntax The following syntax is used in the examples- reduce() This function is defined under the functools module str() This is a built-in method in Python that can convert the specified value into a string. filter() The ...
