Write a C program to display the digits of a number as pyramid
(i) Given an integer number, write a program that displays the number as follows :
First Line : all digits
Second Line : all excepts first digits
Third Line : all excepts first two digits
………..
Last Line : the last digit.
For example, the number 5678 will be displayed as :
5 6 7 8
6 7 8
7 8
8
Solution:
#include<stdio.h>
int main(){
int x,arr[16],i=0,j;
printf("Enter the integer value: ");
scanf("%d",&x);
while(x > 0){
arr[i]= x % 10;
x = x / 10;
i++;
}
for(j=i-1; j >= 0; j--){
for(i=j; i>=0;i--){
printf("%d ",arr[i]);
}
printf("\n");
}
return 0;
}
Write a C program to convert any integer to its binary equivalent.
#include <stdio.h>
int main(){
int x,arr[16],i=0;
printf("Enter the integer value: ");
scanf("%d",&x);
while(x > 0){
arr[i]= x % 2;
x = x/2;
i++;
}
for(i=i-1; i>=0; i--){
printf("%d ",arr[i]);
}
return 0;
}
Software Engineering Practical using PHP/MySQL
Software project: Desktop / Web based
Platform: any
Backend Language: PHP/MYSQL
Frontend: HTML + CSS + JS
Server: Local server (XAMPP/WAMP) / Web Server
Text Editor: Notepad++ / Sublime Text/ VS code etc.
1. Install XAMPP. Download from: https://www.apachefriends.org/download.html
2. Start xampp control panel
3. Start PHP (Apache) and MySQL service
4. Click ‘Explorer’ >> htdocs folder (server root)
5. Create project folder ’21q’
6. Create index.html / index.php file in ’21q’ folder
7. Write some html code in index file
8. Browse http://localhost/21q from any browser e.g. Google chrome
Note: browsing localhost/21q will automatically run the index file.
9. Create a php file test.php and write some php code then browse http://localhost/21q/test.php
Note: to run php program file we must use Local/web server. PHP code must be written in php tag (<?php //program code here… ?> )
10. Create a database and a table in database server by browsing http://localhost/phpmyadmin from any browser
11. Write php code using php/mysql functions to connect and query in database

(a) Write a program to find the area of a circle. (Use p as a symbolic constant).
(b) Write a program to convert the given temperature in Fahrenheit to Celsius and vice versa.
(c) Write a program to find the all-possible roots of a quadratic equation.
(d) Write a program that takes a floating-point number as input and display the floating point and integer part separately.
(e) Write a program to find the factorial of an integer.
(f) Write a program that takes an integer as input and display it in reverse order.
(g) Write a program to convert any integer to its binary equivalent.
(h) Write a program in C to determine and print the sum of the following harmonic series for a given value of n : s = 1 + 1/22 + 1/33 …….. + 1/nn.
(i) Given an integer number, write a program that displays the number as follows :
First Line : all digits
Second Line : all excepts first digits
Third Line : all excepts first two digits
………..
Last Line : the last digit.
For example, the number 5678 will be displayed as :
5 6 7 8
6 7 8
7 8
8
(j) Write a program in C that prints the smallest of the three numbers.
(k) Write a program in C to compute the sum of the digits of a given integer number. For example, if the input number is 123 then output should be 6.

(a) Write a program to multiply two matrices.
(b) Write a program to initialize all the diagonal elements of a two-dimensional array to 1 and others to 0.
(c) Write a program that reads a string from keyboard and determines whether it is a palindrome or not.
(d) Write a program to evaluate the expression using user defined function:
f(x) = x-x3/3! + x5/5!-x7/7!+…..
(e) Write a program to find the first n Fibonacci numbers.
(f) Write a program using an array of structure to read the number of three subjects for n students and sort them according to their position. (1st, 2nd, 3rd ……)
(g) Given two one-dimensional arrays A and B which are sorted in ascending order. Write a program to merge them into a single sorted array C that contains every item from arrays A and B, in ascending order.
(h) Write a program to copy one string into another and count the number of characters copied.
(i) Write a program in C to concatenate the three arrays namely first-name, second-name, third-name into one string to be called name.
Section – 3 (Pointers and File Management) (Answer any one) 15 ´ 1 = 15
(a) Write a program using pointers to read an array of integers and print its elements in reverse order.
(b) Write a program using pointers to compute the sum of all elements stored in an array.
(c) Write a program to copy the contents of one file into another.
(d) Write a program to read data from keyboard, write it to a file called, INPUT, again read the same data from the INPUT file and display it on the screen.
(e) Write a program that appends one file at the end of another.
(f) Write a program to open a file named INVENTORY and store in it the following data :
Item Name Number Price Quantity

CCC-3 527 32.15 115
Extend the program to read this data from the file INVENTORY and display the inventory table with the value of each item.
CodeBlocks – C and C++ Compiler Software
- Download and install Compiler software (CodeBlocks).
http://www.codeblocks.org/downloads/binaries/Download your version compatible with your system. Notice ‘mingw’ word in the file name. Because ‘mingw’ is the compiler included in CodeBlocks software.
Ex: codeblocks-20.03mingw-setup.exe - Open New file ( File >> New >> Empty file )
- Save the file ‘welcome.c’ or ‘welcome.cpp’
- Write the sample code given below:
C Program File Name: welcome.c
#include<stdio.h>
void main()
{
printf("Welcome to C Programming!");
}
C++ Program File Name: welcome.cpp
#include<iostream>
using namespace std;
int main()
{
cout << "Welcome to C++ Programming!";
return 0;
} - Compile/Build the file ( Build Menu >> Build ) or keyboard Shortcut ‘Ctrl+F9’
- Run/Execute the file (Build Menu >> Run ) or keyboard Shortcut ‘Ctrl + Shift + F9’
- Success! Your are ready for programming.
