Chapter -9 Computer can solve variety of problems from the easiest to the most complex ones. To solve a problem it needs to be given a complete set of instructions. We can solve any problem using the steps mentioned: 1. Define the problem. 2. Identify the input, output and constraint of the problem. 3. Identify different alternatives of solving the problem. 4. Choose the best possible alternative from the above list. 5. Prepare detailed stepwise instruction set of the identified alternative. 6. Compute results using this instruction set. 7. Check correctness of the answer obtained. Steps 1 to 5 are performed by person who needs the solution, while step 6 and 7 are performed by a computer. A flowchart is a technique in which we use pictorial representation of every action that we perform within the machine process that solves a problem. A set of symbols, showing different actions, is used to represent a flowchart. The symbols are also called components of flowcharts. Start and End :
