R .B.S COLLEGE OF TECHNOLOGY AND MANGEMENT
---------------------------------------------------------------------- AGRA
B.C.A FIRST SEMESTER
>>>> LAB ASSINGMENT>>>> --------------------------------------------------------------------------- 1- Write a program to compute area and circumference of a circle. Program-

#include<stdio.h>
#include<conio.h>
Void main()
{
float radius,circumference,area;
clrscr();
printf(“the radius of circle= ”);
scanf(“%f”,radius);
circumference=2*3.14*radius;
area=3.14*radius*radius;
printf(“the area of circle=%f \n the circumference=%f”,area,circumference); getch();
}

2- Write a program converts a temperature from Celsius to Fahrenheit. Use the following formula: F = 1.8 x C + 32 . Program-
#include<stdio.h>
#include<conio.h>
void main()
float celsius, farenheit;
clrscr();
printf(“temperature in celsius= ”);
scanf(“%f”,celsius);
farenheit=1.8*c+32;
printf(“\nthe temp in farenheit=%f”,farenheit);
getch();
}

3- Write a complete C Program that prompts the user for the Cartesian Coordinates of two points (x1, y1) and (x2, y2 ) and displays the distance between them computed using the following formula : Distance =

Program-
#include<stdio.h>
#include<math.h>
#include<conio.h>
Void main()
{
float x1,x2,y1,y2,distance;
clrscr();
printf(“the co-ordinates are=”);
scanf(“%f %f %f %f”, &x1,&x2,&y1,&y2);
distance=sqrt((x1-x2)*(x1-x2)+(y1-y2)*(y1-y2));
printf(“distance=%f”,distance);
getch();
}
4.Write a program that reads the lengths of two sides of a triangle and the angle between them and calculates the length of the third side using the following formula:

Program-
#include<stdio.h>
#include<math.h>
#include<conio.h>
Void main()
{
float side1,side2 ,side3,angle;
clrscr();
printf(“enter the two sides of triangle and angle between them=”); scanf(“%f %f %f “,&side1,&side2 &angle);
side3=sqrt((side1*side1+side2*side2-2*side1*side2*Cos(angle))); printf(“the third side is=%f”,side3);
getch()
}
5.Write a program that reads the volume of a sphere and finds the radius of it.  

8.Write a program to generate Square, Cube, and Square Root of positive numbers from 1 to any Limit Entered by user. (Note: Solve using for loop).

Program-

#include<stdio.h>
#include<math.h>
#include<conio.h>
void main()
{
long int i=1,n,square,cube,square_root;
clrscr();
printf("enter the value=");
scanf("%ld",&n);
for(i=1;i<=n;i++)
{
square=n*n;
printf("square=%ld",square);
cube=n*n*n;
printf("\ncube=%ld",cube);
square_root=sqrt(n);
printf("\nsquare_root=%ld",square_root);
getch();
}
}
9.Write a program to find the roots of a quadratic equation. Consider the case of imaginary roots. Program-

#include<stdio.h>
#include<math.h>
#include<conio.h>
void main()
{
float a,b,c,discriminent,root1,root2;
clrscr();
printf(“enter the values of a ,b,andc=”);
scanf(“%f %f %f”,&a,&b,&c);
discriminent=b*b-4*a*c;
if (discriminent<0)
printf(“roots are imageinary”);
else
{
root1=(-b+sqrt(discriminent))/(2.0*a);
root2=(-b-sqrt(discriminent))/(2.0*a);
printf(“\n\nroot1 =%5.2f\n\nroot2=%5.2f”,root1,root2”); getch();
}
}
10.Write a program that reads three integer numbers and prints the highest among them. #include<stdio.h>
#include<conio.h>
void main()
{
int a,b,c;
clrscr();
printf(“enter the value of a,b, and c=”);
scanf(“%d%d%d”,&a,&b,&c);
if(a>b&&a>c)
printf(“a is greatest”);
else if(b>c)
printf(“b is greatest”);
else
printf(“c is greatest);
}
11.Write a program that prompts the user for the day number (0 to 6) and prints the day name (Saturday to Friday)...
