Program 1

Write a C program that reads a single integer value from the command line. It will come into your program as argv[1]. Remember that argv[1]?s type is a pointer to a character that begins a sequence of characters that end in a null byte (i.e., null terminator). In other words, it is what is agreed upon as a string. String is not a base type within the C language.

The number you are getting though argv[1] could be either a negative number, a positive number, or zero. Your program should call the absolute value function ? abs ? and it then prints out the absolute value of the number entered. Browse Appendix D to determine which header file you should include. Don?t create your own absolute value function. Check out the atoi function as well. For example,

$ ./assignment04pe01 -6 would cause 6 to be printed. $ ./assignment04pe01 4 would cause 4 to be printed.

Program 2

Write a C program that prints the number of command line arguments. This is the number that is stored in the argument: argc. For example,

Programming Exercise 2: argc

$ ./assignment04pe02 $ ./assignment04pe02 511 Mel Ott Life is good $ ./assignment04pe02 Jem and Scout 

Name your program assignment04pe02.c

would print out 1 would print out 7 would print out 4

Program 3

Read an integer or floating point value from the command line. It will come into your program as argv[1]. Remember that argv[1]?s type is a pointer to a character that begins a sequence of characters that end in a null byte. In other words, it is what is agreed upon as a string. String is not a base type within the C language.

For example,

 $ ./assignment04pe03 4.3

prints out the trigonometric sine value of the number represented by argv[1]. You would do this by calling the proper functions that are found in Appendix D of your textbook. Check out the atof function.

Program 4

The area of a rectangle is its length times its height. Write a C program that inputs two floating point numbers from the keyboard that represent the length and the height of a rectangle. Your program should output the area of the rectangle. If you use the type double to declare your variables, you will need to use the %lf format code with scanf. See the back cover pages of your book. If you use the type float to declare your variables, you will need to use the %f format code with scanf. The function printf, on the other hand, use %f for both double and float types. These little tidbits are in your textbook.
