Activity 1 2 Minutes

Program & Programming What is the difference between the program and the programming ? Program is : a sequence of statements intended to accomplish a task. Programming is : a process of problem solving

Steps of Programming Process Design an algorithm Test your algorithm Use the program Analyze Problem Implement algorithm Algorithm??

Algorithm A set of steps that are followed in order to solve a problem or to complete a specific task.
