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 …
Exercise 1-23. Write a program to remove all comments from a C program. Don’t forget to handle quoted strings and character constants properly. C comments don’t nest. Approach The core challenge is that the same character sequence means completely different things depending on context. A /* inside a string literal is not a comment. A …
Exercise 1-21. Write a program entab that replaces strings of blanks by the minimum number of tabs and blanks to achieve the same spacing. Use the same tab stops as for detab. When either a tab or a single blank would suffice to reach a tab stop, which should be given preference? Approach entab is …
C Program to Generate the graph sheet using the grphics.h library. To use graphics.h, we have to install the drivers in to the the system by using the initgraph() function. Here we derive the graph of input sizes verses time taken for input sizes. x axis represents inputs(0,10000,20000,—-), y axis rep time(0,0.05,0.1,0.15—). Read more about …
Linear Regression is the predicting the value of one scalar variable(y) using the explanatory another variable(x). Linear regression is represented by the equation Y = a + bX, where X is the explanatory variable and Y is the scalar variable. The slope of the line is b, and a is the intercept. For linear list …
Radix Sort is a non-comparison sorting algorithm — it never compares two elements directly. Instead, it sorts by processing individual digits, one digit position at a time from least significant to most significant (LSD approach). This lets it sort integers in O(n) time for a fixed number of digits, breaking the O(n log n) lower …
