The flow chart is a very important tool by which we can understand the flow of algorithms and program very easily. It is a pictorial representation of step by step solution to a problem. Programmer often uses it as a program planning tool for visually organizing steps necessary to solve a problem. It uses boxes of different shapes that denote the different types of instruction.
The set of rules that define how a particular problem can be solved an infinite number of steps is known as an algorithm. A good algorithm helps us to create a good program.
A Flowchart is a diagram that uses graphic symbols to depict the nature and flow of the steps in a process. Another name for this tool is “flow diagram.”

Note: To solve a problem in the simplest and better way we use an algorithm and flowchart so first, we will write an algorithm then we will make a flow chart for that problem.
Flowchart Questions & Answers
1)WRITE AN ALGORITHM AND DRAW A FLOWCHART FOR THE ADDITION OF TWO NUMBERS THAT ARE INPUT BY YOU AND DISPLAY THEIR SUM.
1. START 2. INPUT A,B 3. C=A+B 4. PRINT C 5. STOP
2) WRITE AN ALGORITHM AND DRAW A FLOWCHART TO PRINT NUMBERS FROM 1 TO 100.
1. START 2. I = 1 3. WHILE I <= 100 REPEAT STEPS 4 AND 5. OTHERWISE MOVE TO STEP 6. 4. PRINT I 5. I = I + 1 6. STOP
