Due Date:

Midnight, Tuesday March 19

Note: No late projects will be accepted.

Point Value:

This project is worth 25 points.

Objectives:

To learn to use the gcc compiler
To become familiar with syntax error messages generated by the gcc compiler

Assignment:

The assignment is as follows:

Using a text editor, type in the C program shown in the "The Program" section below. Type it in EXACTLY AS SHOWN, including all spacing. (Three exceptions in the header comment: 1) insert YOUR name as the author, 2) insert YOUR social security number, last four digits only, and 3) insert YOUR e-mail address.) Make sure to save the program with the file name proj4.c.
Compile the program using the command

Correct any compilation errors (if any) that you receive and recompile until you receive no errors.
Look at your directory to make sure that the file a.out is there. This is your executable program.
Run the program a few times using different sets of numbers to be sure that it works. To run your program, type a.out at the prompt.
E-mail your source code (proj4.c) as an attachment to Zhipeng (zhipeng1@cs.umbc.edu). Do NOT send a copy of your executable (a.out). Make the Subject of your e-mail Project 4 so that Zhipeng knows what it is! He will compile and run your program, then e-mail you your grade for the assignment.

The Program:

/************************************************************** ** Filename: proj4.c ** Author: put your name here ** Date Written: 3/12/01 ** SSN: put your SSN here (last 4 digits only is OK) ** Section: 0601 ** E-mail: put your UMBC e-mail address here ** Description: This program asks the user to enter integers, ** one at a time, until the user enters a zero. ** The largest integer is computed and displayed. ***************************************************************/ #include <stdio.h> int main() { int number; /* integer entered by the user */ int largest; /* largest entered read */ /* Prompt the user for an integer and read it */ /* Initialize the largest integer */ printf("Please input an integer, 0 to end: "); scanf("%d", &number); largest = number; /* Continue to prompt and read until a zero is read */ /* Keep track of the largest integer entered */ while (number != 0) { if (largest < number) { largest = number; } printf("Please input an integer, 0 to end: "); scanf("%d", &number); } /* Display the largest integer entered */ printf("\nThe largest integer entered was %d.\n", largest); return 0; }
