Computing the difference between two dates in C is a classic exercise that most tutorials get subtly wrong — hand-rolled day counting that forgets the century leap-year rules, so 1900 counts as a leap year when it wasn’t. The C standard library already solved this: convert each date to a time_t with mktime(), subtract with …
Replacing a substring means finding every occurrence of one piece of text inside a string and swapping it for another — for example, turning “the cat sat on the mat” into “the cog sog on the mog” by replacing “at” with “og”. C has no built-in function for this (unlike Python’s str.replace()), so it’s a …

C Program to demonstrate how the escape characters work.Escape character is the single character, and it is compiled as the character constant.Escape characters are used to solve the c format problems.An escape sequence is denoted by using the backslash () as an escape character, followed by a single character indicating the nonprintable character desired.Read more …
Finding the position of a substring means locating the index where one string first appears inside another — for example, “world” starts at index 6 in “hello world”. This is one of the most common string operations in C, used for parsing text, validating input, and implementing search features. The standard library already provides strstr() …
