K&R C Programs Exercise 4-10

Exercise 4-10. An alternate organization uses getline to read an entire input line; this makes getch and ungetch unnecessary. Revise the calculator to use this approach. The original calculator reads the input one character at a time via getch/ungetch. This exercise replaces that machinery with a line-buffer approach: read the whole line into a static …

K&R C Programs Exercise 4-9

Exercise 4-9. Our getch and ungetch do not handle a pushed-back EOF correctly. Decide what their properties should be if an EOF is pushed back, then implement your decision. The bug: K&R’s original implementation uses char buf[BUFSIZE]. When ungetch(EOF) is called, EOF (typically -1) is stored as char. On platforms where char is unsigned, -1 …

C Program to print ASCII values of all characters.

C Program to print ASCII values of all characters.ASCII value is the American Standard Code for Information Interchange.ASCII value is the numerical value, or order, of an character. There are 128 standard ASCII characters, numbered from 0 to 127. Extended ASCII adds another 128 values and goes to 255. The numbers are typically represented in …

Strong Number in C – Check Using Digit Factorials

A strong number in C (also called a special number or Peterson number) is a number where the sum of the factorials of its individual digits equals the number itself. For 145: the digits are 1, 4, and 5. Their factorials are 1! = 1, 4! = 24, 5! = 120. The sum 1 + …
