Elementary Statistics and Computer Application

The STOP and END statements

The form of STOP statement is

eg :
500 STOP
When this statement is encountered in a program, the execution of the program stops. There may be more than one STOP statement or none at all in a program. It may be placed in the program wherever necessary. STOP is also known as logical end of the program.
The end of a program is always indicated by the END statement. The form of this statement is
l END
This must be the last statement in a program. This indicates the physical end of the program.
eg :
1000 END
The computer will stop the execution of the program when the END statement is executed. Even if some more statements are available after END it will not be included for execution.
Program
Let X = 1.11, Y = 2.22, Z= 3.33. Develop a program to compute X2+Y2 +Z2 and
X3+Y3 +Z3.


10 X=1.11
20 Y=2.22
30 Z=3.33
40 S =X^2+Y^2+Z^2
50 C= X^3+Y^3+Z^3
60 PRINT X, Y, Z, S, C
70 STOP
80 END

Program
One foot = 12.0 inches, one inch = 2.54 centimeters. Develop a program to compute inches and feet of 76.2 centimeters. Print the result as
CM = INCHES = FEET =

10 REM PROGRAM TO COMPUTE INCHES AND
20 REM FEET WHEN GIVEN DATUM IS IN CM
30 READ A, B, C
40 DATA 12.0, 2.54, 76.2
50 J=C/B
60 REM VARIABLE J STORES THE NUMBER OF
70 REM INCHES IN C CENTIMETERS
80 F=J/A
90 REM VARIABLE F STORES THE NUMBER OF
100 REM FEET IN J INCHES
110 PRINT “CM =”, C,”INCHES=”,J.”FEET =”, F
120 STOP
130 END

Program
Develop a program to convert temperatures, given in degrees centigrade(C), to degrees Fahrenheit (F) using the formula
F=(9/5)C +32

10 REM TO CONVERT TEMPERATUER IN
20 REM CENTIGRADE TO FAHRENHEIT
30 PRINT “TEMP IN CENTIGRADE”;
40 INPUT C
50 F=(9/5)*C +32
60 PRINT
70 PRINT “TEMP IN FAHRENHEIT=”;F
80 END
