### What is meant by syntax of programming language?

Answer : The grammatical rules of a programming language to write programs are referred to as syntax of that programming language.

### What is meant by problem analysis?

Answer : The process of understanding the problem for developing its solution is called the analysis problem.

### When runtime error occurs?

Answer : A runtime error occurs when the program directs the computer to perform an illegal operation such as dividing a number by zero.

### Define Problem solving?

Answer : Problem solving is a skiing which can by developed by following a well organized approach.

### What is coding?

Answer : The process of converting an algorithm to a program using a programming language is known as coding.

### Name of strategy for problem solving method?

2. Preliminary algorithm
3. Refining the algorithm

### Write limitations of flowchart?

Answer : 1. It is difficult to draw flowchart for complex problems
2. If alterations are required the flowchart is to be redrawn

### What is the difference between syntax and logical error?

Answer : A syntax error occurs when the program violates one or more grammatical rules of the programming language. These are detected during the execution of a program. Computer displays an errors message

### Define documentation?

Answer : Documentation is a detailed description of a programs algorithm design coding method testing and proper usage.

### Write steps that are involved in development of algorithm?

Answer : Algorithm development involves the following steps to carry out
1. Step Investigation
2. Preliminary algorithm
3. Refining the algorithm

### Is it important to know syntax of programming language to solve a problem on computer?

Answer : To solve a problem on a computer it is necessary to know the syntax otherwise an error is occur is known as syntax error. A syntax error occurs when the program violates one or more grammatical rules of the programming language.

### What is meant by program maintenance?

Answer : Program maintenance is the process of upgrading the program to accommodate the new requirements of the users and to correct errors in the program.

### Write the use of flow lines?

Answer : Flow lines represent the direction of flow of information in the flowchart between various blocks.

### Define bugs?

Answer : When a program does not produce desired result then contain the error. These errors are called bugs.

### What is the importance of program design in problem solving?

Answer : Designing he program is very important is problem solving. The problem can only be saved successfully if an efficient program is designed. ### Symbol stand for? is stands for connector

### Define the process of analyzing a problem?

Answer : Analyzing is the decomposition of a bigger problem in sub-problems At this stage the big problem decomposed into sub-problems Rather on concentration the bigger problem as a whole we try to solve each problem separately It leads to a simple solution.

### Define algorithm?

Answer : An algorithm is a finite set of steps which if followed accomplish a particular tasks.

### Which type of Errors are difficult to find and why?

Answer : Logical Eros are the most difficult errors to locate or find because the translator compiler or interpreter does not report any error message for a logical error.

Sum
N=0
DO WHILE
Sum= Sum+N
PRINT Sum
N=N+1
END DO
END
