算法：
算法一词的意思是“在计算或其他解决问题的操作中要遵循的一个过程或一组规则”。因此，算法是指一组规则/指令，这些规则/指令逐步定义了如何执行工作以获得预期结果。
让我们看一个例子，以便更好地理解。作为程序员，我们都知道线性搜索程序。 (线性搜索)
线性搜索算法：
1. Start from the leftmost element of arr[] and
one by one compare x with each element of arr[].
2. If x matches with an element, return the index.
3. If x doesn’t match with any of elements, return -1.
在这里，我们可以看到如何用简单的英语解释线性搜索程序的步骤。
流程图：
流程图是算法的图形表示。程序员经常将其用作解决问题的程序规划工具。它利用它们之间相互连接的符号来表示信息的流动和处理。
为算法绘制流程图的过程称为“流程图”。
示例：绘制流程图以输入用户输入的两个数字，并显示两个数字中最大的一个
让我们看看算法和流程图之间的区别：-
| S.NO | Algorithm | Flowchart |
|---|---|---|
| 1. | Algorithm is step by step procedure to solve the problem. | Flowchart is a diagram created by different shapes to show the flow of data. |
| 2. | Algorithm is complex to understand. | Flowchart is easy to understand. |
| 3. | In algorithm plain text are used. | In flowchart, symbols/shapes are used. |
| 4. | Algorithm is easy to debug. | Flowchart it is hard to debug. |
| 5. | Algorithm is difficult to construct. | Flowchart is simple to construct. |
| 6. | Algorithm does not follow any rules. | Flowchart follows rules to be constructed. |
| 7. | Algorithm is the pseudo code for the program. | Flowchart is just graphical representation of that logic. |
