K&R C Programs Exercise 5-12

Exercise 5-12. Extend entab and detab to accept the shorthand entab -m +n to mean tab stops every n columns, starting at column m. Choose convenient (for the user) default behavior. Two new argument forms extend the programs from Exercise 5-11: -m sets the starting column and +n sets the interval. So detab -4 +3 …

K&R C Programs Exercise 5-10

Exercise 5-10. Write the program expr, which evaluates a reverse Polish expression from the command line, where each operator or operand is a separate argument. For example, expr 2 3 4 + * evaluates 2 * (3+4). The K&R RPN calculator from Chapter 4 reads from stdin. This version reads from argv instead — each …

C Program to demonstrate sscanf statement.

C Program to demonstrate the ‘sscanf’ statement.sscanf statement reads formatted data from the string, Different syntax of sscanf are:A = sscanf(str, format)A = sscanf(str, format, sizeA)[A, count] = sscanf(…)[A, count, errmsg] = sscanf(…)[A, count, errmsg, nextindex] = sscanf(…).Read more about C Programming Language . /************************************************************ You can use all the programs on www.c-program-example.com* for personal …

C Program to demonstrate sprintf statement.

C Program to demonstrate the ‘sprintf‘ statement. This example is a bit lame as the same effect can be seen with a ‘printf’. But, it does show a string being built and passed into a function.

K&R C Programs Exercise 5-9

Exercise 5-9. Rewrite the routines day_of_year and month_day with pointers instead of indexing. Replace every daytab[leap][i] with pointer arithmetic. The key step: instead of indexing into the 2D array, take a pointer to the correct row (const char *p = daytab[ly]) and use p[i] or *(p + i) to access elements. The loop variable can …
