CS 430 – Quiz #1

Name _________________________ Section 1 : __2:00___

Given the following FORTRAN code

NUMBER = 23

REAL1 = 41.2

REAL2 = 567.432

Write the FORTRAN statement(s) that would output the numbers all on one line with 1 space between them.

WRITE (6, 10) NUMBER, REAL1, REAL2

10 FORMAT (1X, I2, 1X, F4.1, 1X, F7.3)

10 FORMAT (1X, I2, F5.1, F8.3)

10 FORMAT (1X, I2, ‘ ‘, F4.1, ‘ ‘, F7.3)

Write the formula for computing the address of an element in a one-dimensional Pascal array

baseAddress + ( index – lowerBound) * size

Use the formula you wrote above to compute the address of A[23] where

• baseAddress is 1000
• each element is 3 bytes long
• the lower bound of B is -3
• the upper bound of B is 41

1000 + (23-(-3)) * 3 = 1000+(23+3) * 3 = 1000+ 26*3 = 1000 + 78 = 1078

What will be output when the following Snobol code is run?

Colors = “orange” | “black” | “green”

“turn at the black house” Colors . Result

Output = result

Instructions = “turn at the orange house”

Instructions Colors = “strange”

Output = Instructions

black

turn at the strange house
