Experiment no. 2 Page no. 7 Topic 3.0 NEW CONCEPTS: Line no. 13 %d: For printing integer valuesCorrection: %d: For printing Decimal integer values.

2.

Experiment no. 2 Page no. 9 Topic 6.0 EXERCISES B.3. Concept in this program is very conflicting, thus it is not necessary at this stage of learning.

3.

Experiment no. 3 Page no. 11 Topic 3.0 NEW CONCEPTS: Only Conditional, Logical, Arithmetic and Relational operators are covered here. Bitwise operators (&, ^, |) are remained. 4.

Experiment no. 3 Page no. 13 Topic 5.0 SAMPLE PROGRAMS: Flowchart: Yes/No tags are remaining, also for displaying ‘First class’, ‘Second Class’ rectangles are used. Here, parallelograms are required. ‘Display Result’ box is not necessary. 5.

Experiment no. 3 Page no. 14 Topic 6.0 EXERCISES B.1. Line no. 6. This line is conflicting. It should be meaningful, such as, if (i==5 && z>50)

6.

Experiment no. 4 Page no. 19 Topic 5.0 SAMPLE PROGRAMS: Program code: This program contains some logical errors. When we enter the character other than ‘a’ to ‘z’ or ‘A’ to ‘Z’ it displays the ‘character is consonant’. The code should be modified as, if((ch>=’a’ && ch<=’z’) || (ch>=’A’ && ch<=’Z)) if(ch==’a’ || ch==’e’ || ch==’i’ || ch==’o’ || ch==’u’ || ch==’A’ || ch==’E’ || ch==’I’ || ch==’O’ || ch==’U’) printf(“Character is vowel”); else printf(“Character is consonant”); 7.

Experiment no. 4 Page no. 21 Topic 5.0 SAMPLE PROGRAMS: Problem statement and program code does not match. Some lines in the program code are remained. The code is wrong after line no 19 and 20. It should be: if(units_consumed<=625) bill_charges=230+0.8*(units_consumed-425); else bill_charges=390+(units_consumed-625); 8.

Experiment no. 4 Page no. 21 Topic 5.0 EXERCISE 6.0 A.1. This program is based on finding real roots of quadratic equations. At this stage such complicated program is not necessary. 9.

Experiment no. 5 Page no. 24 Topic 3.0 NEW CONCEPTS: Last line on this page is: To avoid the execution of statements keyword break is used if the control out of the switch statement. It should be written as: To avoid the execution of statements keyword break is used. It transfers the control out of the switch statement. 10.

Experiment no. 5 Page no. 26 Topic 5.0 SAMPLE PROGRAM: Flowchart: In the given flowchart, third block must be above second block.

Errors in CPR (9017) manual Program code: ‘case’ keyword is written as ‘Case’. It must whole be in small case. For case 4, i.e. division, the output is in the form of integer. We can introduce type casting or type conversion here by converting ‘result’ variable into float data type. Change the line, result = a/b; into result = float(a/b); 11.

Experiment no. 5 Page no. 28 Topic 6.0 EXERCISES C. Two examples are given here. I will suggest to take an example on float values. By which student can understand that float is not allowed in switch-case. 12.

Experiment no. 6 Page no. 30 Topic 3.0 NEW CONCEPTS: General syntax of for loop is given as: for (counter initialization; test counter condition; increment counter) for loop is not always related with counter so, more specifically we can write

it as: for (initialization ; condition ; updation) 13.

Experiment no. 6 Page no. 34 Topic 5.0 SAMPLE PROGRAM: Algorithm: As the flowchart is not for do-while loop step 6 must be shifted in place of step 4. Flowchart: ‘Display the counter’ should be written in parallelogram block, as it is an output statement. Program code: Very simple program code is given here. It can be changed to Fibonacci series or finding the factorial of a number. 14.

Experiment no. 6 Page no. 36 Topic 6.0 EXERCISES B.2. Fourth line in this program is: int j, j; it must be: int i, j;

15.

Experiment no. 6 Page no. 36 Topic 6.0 EXERCISES B.3. Line number 12 of this program contains a variable n. But this variable is not defined anywhere. It should be ‘number’ in place of n. 16.

Experiment no. 7 Page no. 39 Topic 3.0 NEW CONCEPTS. Example: int A[10]; The above statement will reserve 10 consecutive memory allocations to store 10 elements of type integer. In this statement there should be ‘locations’ instead of allocations. 17.

Experiment no. 7 Page no. 40 Topic 5.0 SAMPLE PROGRAM. Flowchart: In the given flowchart, fourth block should be rectangle and fifth should be parallelogram. 18.

Experiment no. 7 Page no. 41 Topic 5.0 SAMPLE PROGRAM. Program Code: There is a logical error in the given program. In the second for loop (line no. 14), the condition given is if(arr[i] < arr[i+1]) max = arr[i]; CPR (FYIF) by Mr. Kute T. B. (Lecturer in IT, KK Wagh Polytechnic, Nashik 2007-2008)

-2-

Errors in CPR (9017) manual Here, value of max should be assigned with arr[i+1] not with arr[i]. If we enter negative numbers, output doesn’t come accurate, so we can prefer one more logic, i.e. max = arr[0]; for(i=0; i<5; i++) { if(arr[i] > arr[i+1]) max = arr[i]; } 19.

Experiment no. 8 Page no. 41 Topic 3.0 NEW CONCEPTS: The declaration of two dimensional array is missing a semicolon.

20.

Experiment no. 8 Page no. 41 Topic 3.0 NEW CONCEPTS: The memory visualization of two dimensional array can be visualized most simply as:

21.

Experiment no. 8 Page no. 41 Topic 5.0 SAMPLE PROGRAM: The problem statement contains a 2 X 2 matrix but, the actual program is based on a 3 X 3 matrix. 22.

Experiment no. 8 Page no. 41 Topic 5.0 SAMPLE PROGRAM: There should be an opening curly brace after line no. 30 and closing curly brace after line no. 33 to view the output matrix properly. such as: for (i=0; i<3; i++) { for (j=0 ;j<3; j++) printf(“\t%d”,C[i][j]); printf(“\n”); } 23.

Experiment no. 8 Page no. 48 Topic 6.0 EXERCISES B.1. Last line of this program is: printf(“\n %d%d%d”, *A,A[3][3],A[2][1]); At this stage of learning, use of * operator is not necessary. It will be some bit confusing for the students also. CPR (FYIF) by Mr. Kute T. B. (Lecturer in IT, KK Wagh Polytechnic, Nashik 2007-2008)

Experiment no. 10 Page no. 59 Topic 6.0 EXERCISES B.1. Function prototype is of funct1( ) and function call (line no. 8) is of funct2( ). Also, any of the function is not defined here. 31.

Experiment no. 10 Page no. 60 Topic 6.0 EXERCISES B.2. Function f1( ) should have prototype here or it must be declared above main( ) function. 32.

Experiment no. 10 Page no. 60 Topic 6.0 EXERCISES C.1. main( ) function is not ended with a closing curly brace.

33.

Experiment no. 10 Page no. 60 Topic 6.0 EXERCISES C.3. Prototype of function swap( ) contains intx and inty. There should be space between int and x as well as int and y. 34.

Experiment no. 11 Page no. 62 Topic 4.0 NEW CONCEPTS: Syntax of the structure contains square brackets. It is not necessary there else it will be considered as the part of syntax of the structure. 35.
