Finding largest two numbers from N numbers

Finding largest two numbers from N numbers:  This C program example finds the two largest numbers from the list of 'N' numbers. Mechanism: In this program, we have declared the variable of: Size Input First largest Second largest  First, we take input of size and then we enter a for loop which executes for 'size' times. This program is designed in such a way that it checks all negative and positive integers. This program uses an if else and else if structure and for loop structure structure to execute the logic of the program....

Do While In C++

Do While C: In this C tutorial for beginners, we are going to discuss the third repetition structure known as do…while loop in c. In for loop, initially the loop condition is checked and then the statement is executed according to the loop condition. But if you want to execute the statement initially(first) and then check the loop condition then we use do…while loop. Syntax: do       statement;while (expression); Statement...

For Loop In C++

For Loop In C++: The while loop discussed in our previous tutorial is a general form which can be implemented in a different form of repetitions. In this C tutorial for beginners, we are going to study second repetition structure known as for loop c. In C++, for loop is a specialized form of while loop. Its primary purpose is to simplify the writing of counter-controlled loops.In while loop, you had to declare a counter variable and write an extra...

While Loop In C++

While Loop In C++: In C++, there are times when it becomes necessary to repeat a set of statements several times. One way is to write the code in the program over and over but that would make the code very long and it would become a messy code. Just imagine that if you have to repeat a set of statements 100 times then you have to write that 100 times again and imagine where the length of the code would go. Fortunately, we have a way that finishes...

Preprocessor Directives In C

Preprocessor directives in C: In C++, we don’t have large number of operations. Only small number of operation like arithmetic and assignment operations are available. But to run a C++ program many type of functions are required. C++ has a collection of libraries. We use them to get access to many interesting and important operations. Every library has a unique name and is referred to by a header file. Examples: The function needed to perform input/output (I/O) are contained in the header file iostream.For performing useful mathematical...
