Chapter 3: Control Flow covers C’s branching and looping constructs. It is short (6 exercises) but the exercises are non-trivial: exercise 3-3 implements expand(s1,s2) to expand shorthand like a-z into the full alphabet; 3-4 handles itoa for the most negative integer (a classic overflow trap); 3-5 converts integers to arbitrary bases. These are worked solutions …
A magic square is a square matrix in which the sum of every row, every column, and both main diagonals is the same number (called the magic constant). This C program reads a square matrix and checks whether it is a magic square. Example: 8 1 6 3 5 7 4 9 2 Every row, …
Deleting the vowels from a string is a classic C exercise because the obvious approach — remove a character, then shift everything after it left by one — is O(n²) and fiddly. The clean solution is the two-index in-place filter: one index reads every character, a second index writes only the characters you’re keeping, and …
To delete a file in C, call the standard library function remove() from <stdio.h>: it takes the file name as a string and returns 0 on success. That one line is portable across Linux, macOS, and Windows — no operating-system headers needed. What separates a toy example from production-quality code is what happens when deletion …
Write a C Program to demonstrate strspn function.The strspn() function returns the index of the first character in string1 that doesn’t match any character in string2. If all the characters of the string2 matched with the string1, strspn returns the length of the string1.
