A. Write a program with sub procedure to input length,breadth and height. Then, calculate the area of four walls where A=2*H(L+B).
Answer:
DECLARE SUB AREA(L,B,H)
INPUT "Enter length, breadth and height : ";L,B,H
CALL AREA(L,B,H)
END
SUB AREA (L,B,H)
A = 2 * H * (L + B)
PRINT " Area of four wall : ";A
END SUB
B. Write a program with sub procedure to find the volume of box where V=LxBxH.
Answer:
DECLARE SUB VOLUME(L,B,H)
INPUT "Enter length, breadth and height : ";L,B,H
CALL VOLUME(L,B,H)
END
SUB VOLUME (L,B,H)
V = L * B * H
PRINT " Volume of a box : ";V
END SUB
C. Write a program to input two different numbers in the main module then print the greater number using sub procedure.
Answer:
DECLARE SUB CHECK(A,B)
INPUT "Enter two numbers : ", A,B
CALL CHECK(A,B)
END
SUB CHECK(A,B)
IF A>B THEN
PRINT A;" is greater"
ELSE
PRINT B; " is greater"
END IF
END SUB

B. Write a progran to input three different numbers in the main module and then print the average using a sub-procedure.
Answer:
DECLARE SUB AVERAGE(A,B,C)
INPUT "Enter three numbers : ", A,B,C
CALL AVERAGE(A,B,C)
END
SUB AVERAGE(A,B,C)
AVG = (A + B + C) / 3
PRINT " Average of three numbers : ";AVG
END SUB

PI = 3.14
CALL AREA(R)
END
SUB AREA(R)
A = PI * R ^ 2
PRINT " Area of circle : ";A
END SUB
