K&R C Exercise 2-2: Loop Without && or ||

Exercise 2-2. Write a loop equivalent to the for loop below without using && or ||: for (i = 0; i < lim – 1 && (c = getchar()) != ‘\n’ && c != EOF; ++i) s[i] = c; Understanding the Problem The && operator in C is a short-circuit operator: if the left operand …

K&R C Exercise 2-1: Determine Ranges of Integer Types

Exercise 2-1. Write a program to determine the ranges of char, short, int, and long variables, both signed and unsigned, by printing appropriate values from standard headers and by direct computation. Harder if you compute them: determine the ranges of the various floating-point types. Approach The exercise splits neatly into two halves. The straightforward half …

K&R C Exercise 1-24: Rudimentary C Syntax Checker

Exercise 1-24. Write a program to check a C program for rudimentary syntax errors like unmatched parentheses, brackets, and braces. Don’t forget about quotes, both single and double, and comments. (This is hard to do in full generality.) Approach The obvious approach — keep a counter for each bracket type and check it reaches zero …

C Program to implementing two Stacks on Single Array.

Data structures using C, Stack is a data structure in which the objects are arranged in a non linear order. In stack, elements are aded or deleted from only one end, i.e. top of the stack. In this program, we implement the two stacks using the single array. Read more about C Programming Language . …

K&R C Exercise 1-22: Fold Long Lines at Word Boundaries

Exercise 1-22. Write a program to “fold” long lines into two or more shorter lines after the last non-blank character that occurs before the n-th column of input. Make sure your program does something intelligent with very long lines, and if there are no blanks or tabs before the specified column. Line folding is the …
