31st October, 2021 (For July, Session)
15th April, 2022 (For January, Session)

1c) Using table and lists create two web pages, first displaying the list of all the course writers of
BCS053 course. This information should be created in a table, the table should have a heading. The columns of the table should display the Unit number, unit name and unit writer’s name. The second page should display an unordered list, displaying the list of expert committee members of BCS053 course. You should use <div> tags, wherever needed; and create an internal CSS file, which formats the web pages as follows: (You must submit the HTML and CSS code and the screenshot of pages in a browser window)

(i)
(ii)

The headings of the table must be in Bold and all other content should be in italics font.
The table heading should be in different shade. The data rows of the table should have
alternatively light yellow and light green color. The background of the table should be
light grey.

(iii) The font of the unordered list should be "Arial" with font size of 12 points. The
background colour of list should be light red.
(iv) You must demonstrate how changes in CSS can change the display at the time of Viva.

2022-02-19T03:24:00.005+05:30

SURFACE AREAS AND VOLUMES

EXERCISE 13.1

Q1. A plastic box 1.5m long, 1.25 m wide and 65 cm deep, is to be made. It is to be open at the top. Ignoring the thickness of the plastic sheet, determine:

(i). The area of the sheet required for making the box.
(ii). The cost of sheet for it, if a sheet measuring 1m² cost Rs 20.

Solution:- (i).

(Given): l = 1.5 m, b = 1.25 m, h = 65 cm = 0.65 m

Method-1:

Surface Area of Cuboid = 2(lb + bh + hl)

∵ Box is to be open at the top

∴ Required Area of plastic sheet = (Surface Area of the Box) - (Area of top)

= 2(lb + bh + hl) - (l x b) [or 2(bh + hl) + lb]

= 2(1.5 x 1.25 + 1.25 x 0.65 + 0.65 x 1.5) - (1.5 x 1.25)

= 2(1.875 + 0.8125 + 0.975) - (1.875)

= 2(3.6625) - (1.875)

= 7.325 - 1.875

= 5.45 m²

Method-2:

Surface Area of Cuboid = 2(lb + bh + hl)

∵ Box is to be open at the top

∴ Required Area of plastic sheet = (Surface Area of the Box) - (Area of top)

= 2(lb + bh + hl) - (l x b)

= 2(bh + hl) + lb

= 2(1.25 x 0.65 + 0.65 x 1.5) + (1.5 x 1.25)

= 2(0.8125 + 0.975) + (1.875)

= 2(1.7875) + (1.875)

= 3.575 + 1.875

= 5.45 m²

(ii).

∵ Cost of 1m² sheet is Rs 20

∴ Required cost of sheet for it = 5.45 x 20

= 109 Rs.

Count the no of lowercase letters in a text file bca.txt in C

2020-07-28T18:30:00.001+05:30

Write a program in C to count the no of lowercase letters in a text file bca.txt

This program reads one character at a time by using fgetc() function until the EOF (end of file) returns. Then it checks whether the current character is lowercase or not. If it is a lowercase letter it increments the value of c by 1. It also displays the contents of file named bca.txt. And finally print the total number of lowercase letters present in the file, which is the main purpose to write the program

Program

#include<stdio.h>
#include<conio.h>
void main()
{
FILE *fptr;
char ch;
int c=0;
if((fptr=fopen("bca.txt","r"))==NULL)
printf("File doesn't exist\n");
else
{
while((ch=fgetc(fptr))!=EOF)
{
if(ch>=97&&ch<=122)
c++;
printf("%c",ch);
}
}
printf("\nTotal lowercase letter in bca.txt file is %d",c);
fclose(fptr);
