Exercises 63 Now that you are familiar with all the basic looping constructs provided by the C language, you are ready to learn about another class of language statements that enable you to make decisions during the execution of a program.These decision-making capabilities are described in detail in Chapter 6,“Making Decisions.” First, try the exercises that follow to be certain you understand how to work with loops in C. Exercises 1. Type in and run the nine programs presented in this chapter. Compare the output produced by each program with the output presented after each program in the text. 2. Write a program to generate and display a table of n and n 2 , for integer values of n ranging from 1 to 10. Be certain to print appropriate column headings. 3. A triangular number can also be generated by the formula triangularNumber = n (n + 1) / 2 for any integer value of n.For example, the 10th triangular number, 55, can be generated by substituting 10 as the value for n in the preceding formula.Write a program that generates a table of triangular numbers using the preceding formula. Have the program generate every fifth triangular number between 5 and 50 (that is, 5, 10, 15, ..., 50). 4. The factorial of an integer n,written n!, is the product of the consecutive integers 1 through n.For example, 5 factorial is calculated as 5! = 5 x 4 x 3 x 2 x 1 = 120 Write a program to generate and print a table of the first 10 factorials. 5. The following perfectly valid C program was written without much attention paid to its format. As you will observe, the program is not very readable. (And believe it or not, it is even possible to make this program significantly more unreadable!) Using the programs presented in this chapter as examples, reformat the program so that it is more readable.Then type the program into the computer and run it. #include int main(void){ int n,two_to_the_n; printf("TABLE OF POWERS OF TWO\n\n"); printf(" n 2 to the n\n"); printf("--- ---------------\n"); two_to_the_n=1; for(n=0;n
64 Chapter 5 Program Looping 6. A minus sign placed in front of a field width specification causes the field to be displayed left-justified. Substitute the following printf statement for the corresponding statement in Program 5.2, run the program, and compare the outputs produced by both programs. printf ("%-2i %i\n", n, triangularNumber); 7. A decimal point before the field width specification in a printf statement has a special purpose.Try to determine its purpose by typing in and running the following program. Experiment by typing in different values each time you are prompted. #include int main (void) { int dollars, cents, count; } for ( count = 1; count
