Question

Assignment

• No variables declared after you start writing code, must be declared at the top.

• Reuse all the variables from the first half in the second half, do not make up new variable names.

• You code must be properly formatted.

• You must use the code provided and variables names provided and not add any more variables to your code.

• No for(int I = 0; … no declaring variables except at top of code.

• You cannot use the and operator and must use nested if else statements.

• You read loop must be controlled by scanf not a counter.

• You must initialize sum, min and max to the first number in the file

You will use one file from the first half of this assignment, copy them into the proper directory for this program.

num1.txt

Open the file for reading, read each number one at a time and calculate the Sum, count, max, min, average and create bins for a histogram.

The Assignment

Read file get statistics

Print out a horizontal bar chart for each bin range

1-5, 6-10, 11-15, 16-20

Bin counter variables

There are 4 bin counter variables bc5, bc10, bc15, bc20

Bc5 count of all numbers read that are 1 thu 5, Bc10 count of 6 thu 10 and so forth

When all numbers are read each should have a count of all numbers in each bin’s range.

To Start

Initialize your bin counters and count to 0

Open the file num1.txt for reading

Read the first number and assign it to sum, min, and max

do

Count it

Add to sum

See if is new max or min

Use nested if else statements to add one to the proper bin variable

If n < 6 bc5 = bc5 + 1 and so forth

Do While scanf reads something stored in n

Close file

Print out sum, count, average, min and max

Each bin

Print range so they line up on each line

A loop to print an x for the number stored in the bc variable.

Code

#include <stdio.h>

int main(int argc, char * argv[]) {

int n, count, min, max, sum;

int bc5, bc10, bc15, bc20;

FILE * fileptr;

// your code goes here

printf("Press enter to quit: ");

getchar();

return 0; }
