Hello Everyone!!! Welcome Back!!! At the end of this module, you will be able to control and specify decimal points in float or double data types in C. Intro Many times, we use float data type to represent any result like CGPA marks, statistical data, average or any other data. While representing this data with float, the result will be shown in 6 decimal digits like 1.000000. We are going to code that can specify the decimal digits as our needs and requirements like 1.00 result. Let's See the Before and After Effects Before: I have created one float variable "a" which holds the value of 1. In the next line, I have printed "a". Let's see the output. Here, it prints useless 6 decimal digits. While we want to print mathematical data like the average of marks, it will be very awkward to print 6 decimal digits. So, it can be avoided by the trick given below. After: Trick: Insert the dot and number of decimal digits you want ...

Hello Everyone!!! While solving any problem, it is very important to understand the problem. So, it is necessary to break down the problem into small aspects. Intro In this post, you will be able to understand the problem with the use of Algorithm and Flowchart by breaking down the problem into various steps. Algorithm It is a set of all detailed instructions of the given problem statement. It is necessary to get the outline of the given problem statement. It is step by step process to solve the problem logically. Flowchart It is generally the graphical representation of the algorithm. It is more effective than the algorithm. In the flowchart, inputs/outputs are represented by parallelogram, start/end represented by an ellipse,  process represented by a rectangle. These elements are connected through the arrows i.e. flow of problem. How To Do? It is necessary to break down the problem into small pieces. Follow the steps given below. Get a problem statemen...

Hello Everyone!!! In this tutorial, we are going to install cocoa pods to use them in our project. Intro Cocoa Pods are basically providing readymade external libraries coded with ruby.
