When we call a function with parameters taken by value, it copies the values to be made. This is a relatively inexpensive operation for fundamental types such as int, float, etc. If the parameter is composed of a large compound type, this may result in a certain overhead. For example, let’s consider this following function to combine name, mid name, and surname.
string fullname (string…
A Template is a simple and a very powerful statement in C++. A Template Function may have multiple template parameter types, and the function can still use regular non-templated types. In a previous post, about Function Overloading, we had two add() functions working with…
In the C++ programming language, we can add functions with many parameters, each parameter may have different types. We can add as many parameters as we want by defining its type and its name to be used inside that function separated with ‘,’ coma. We can shape…
In C and C++ programming language there are two parts of a function, Declaration, and Definition.
Function Declarationis the combination of the return type of function, function’s name, and parameters in parenthesis.Function Definitionis the body of the function includes statements and other functions.
In general use, they are defined together as below,
myfunction() // this…
Functions, also known asProceduresorSub-Programs,Sub-Algorithms,allow to structure programs in segments of code to perform tasks. A Function is a group of statements that has function a name and can be called with parameters to operate…
Do you want to learn how to overload a function ? What is Function Overloading ? What does overloaded function means ? How we can use Function Overloading in C++ ? How we can use multiple parameter types in our functions ? Here we go,Function Overloading is used to operate…
While loops allow you to repeat a block of code as long as your specified condition is reached. Loops are used very offend in programming because they save time, reduce errors, and they make code more readable.
1. The While Loop
In the mechanism of the while statement, the condition is evaluated and if it returns true then the code block inside the while loop will be executed, this will…
Merge Sort Algorithm, in another efficient sorting algorithm that divides the input array into two parts and it calls itself recursively for the two parts. Then merges these two sorted parts.It is a Divide and Conquer algorithm. Merge function used to merge two parts…
Quick Sort (QuickSort) Algorithm, also called as partition exchange sort, is a very fast sorting algorithm that developed by British computer scientist Tony Hoare in 1959. It gets a pivot element as pivot and partitions the given array around this element. QuickSort…
Learn To Create Alpha Color Bitmap From A Bitmap By A Given Color In Modern C++
February 23, 2021
Photoshop, GIMP and other professional Photo Editors are capable to convert one color to a alpha color. You choose a color and all same colors of pixels are goes to alpha color which is transparent. These kind of images are good to blend in front o another background of images. You can also add glamorous effects, like gloom, shadows etc. on those images.
In this post we will present to how…
