ESC 251 HW 23 Due: Nov. 3
- (1 pt) The data file trap.in contains a table of values
for some unknown function. Write a program that will count the number of lines in the
- (6 pts) You will need the answer from Problem 1 to do this problem.
Write a program that will use one loop to read in the data values in trap.in into two
array variables. This loop should look something like:
DO i = 1,.....
In a second loop, compute the
area under the function using the trapezoidal rule. Could you use Simpson's
rule for this problem? Why or why not?
- (3 pts) Write a program that will swap two variables. For example,
suppose you declare a and b to be integers and set a = 5 and b = -9.
When your program terminates, the value of a should be -9 and the
value of b should be 5. Your program should work for any values
of a and b.
