MOLINAOCTOBER 3, 2013EXERCISE NO. 3WRITE A PROGRAM TO READ A NUMBER
OF UNITS OF LENGTH (A FLOAT) AND PRINT OUT
THE AREA OF A CIRCLE OF THAT RADIUS. ASSUME THAT THE VALUE OF PI
IS 3.1416. YOUR OUTPUT SHOULD TAKE THE FORM: THE AREA OF A CIRCLE
OF RADIUS UNITS IS SQUARE UNITS.
ALGORITHM1. Initialize value pi equals 3.14162. Input the value
for radius(a).3. Get the value of area (b) of the circle using the
formula b=pi*a*a4. Print the value of the area of the circle.5. End
of program
#include
#include
#define pi 3.1416
float a,b;
main ()
{
printf("Enter the value of lenght/radius:\n");
scanf("%f",&a);
b=pi*a*a;
printf("The area of a circle of radius %f units is %f square
units.",a,b);
getch ();
}
LINE 1: Declared preprocessor by means of #includeLINE 2:
Declared #include< conio.h>, for getch functionLINE 3:
Initialize value of pi to 3.1416LINE 4: Global declaration of
variable a and b as float.LINE 5: main () function
LINE 6: open curly bracket
LINE 7: print f command to print the word Enter the value of
lenght/radius:
LINE 8: Declared scan f
LINE 9: Declaration of formula for the area of the circleLINE
10: Print f command to print the value of area of the circle
LINE 11: declared getch()
LINE 12: close curly bracket,end of program.OUTPUT
EXERCISE NO. 1WRITE C PROGRAM TO PERFORM THE CONVERSIONS OF
DOLLAR TO PESO.
ALGORITHM1. Input value of dollar(a)2. Get the corresponding
value on peso(p) with the formula p=a*43.363. Print the value of
peso4. End of program
#include
#include
int a;
float b;
main ()
{
printf("Enter the value of dollar:\n");
scanf("%d",&a);
b=a*43.36; printf("%d Dollars is equal to %.2f Pesos.\n",a,b);
getch ();
}
LINE 1: Declared preprocessor by means of #include
LINE 2: Declared #include for getch functionLINE 3: Global
Declaration of data type and variable a as integer
LINE 4: Global Declaration of data type and variable b as
floatLINE 5: main () function
LINE 6: open curly bracket
LINE 7: print f command to print the word Enter the value of
dollar:
LINE 8: Declared scan f
LINE 9: Declaration of formula for the conversion
LINE 10: Print f command to print the value in peso
LINE 11: declared getch()
LINE 12: close curly bracket, end of programOUTPUT
EXERCISE NO. 2WRITE A PROGRAM TO READ A FLOAT REPRESENTING A
NUMBER OF DEGREES CELSIUS, AND PRINT AS A FLOAT THE EQUIVALENT
TEMPERATURE IN DEGREES FARENHEIT. PRINT YOUR RESULTS IN A FORM SUCH
AS 100.0 DEGREES CELSIUS CONVERTS TO 212.0 DEGREES FARENHEIT.
ALGORITHM1. Input value of temperature in degrees Celsius.2. Get
the corresponding value of temperature in degrees fahrenheit with
the formula f=c*9/5+32.3. Print the temperature value in degrees
Fahrenheit.4. End of program
#include
#include
float a,b;
main ()
{printf("Enter temperature in degrees Celsius:\n");
scanf("%f",&a); b=a*9/5+32;
printf("%.1f degrees Celsius converts to %.1f degrees
Fahrenheit.",a,b); getch ();
