This C program compares two strings and reports whether they are equal, or which one comes first in dictionary (lexicographic) order. Comparison works character by character: walk both strings together until two characters differ or a string ends, then decide from that first difference. This page shows a manual character-by-character implementation and the standard library …
The time.h library in C provides functions for getting the current date and time, formatting it for display, and converting between representations. The central type is time_t — typically a 32-bit or 64-bit integer counting seconds since the Unix epoch (1970-01-01 00:00:00 UTC). Five key functions cover the most common time operations: time(), ctime(), localtime(), …
C Program to demonstrate macros. Macro is a piece of text that is expanded by the preprocessor part of the compiler. This is used in to expand text before compiling. Macro definitions (#define), and conditional inclusion (#if). In many C implementations, it is a separate program invoked by the compiler as the first part of …
The goto statement in C is an unconditional jump that transfers program control directly to a labelled statement within the same function. While modern C style discourages it, goto is still useful in a few real situations — most commonly for breaking out of deeply nested loops and for centralised cleanup/error handling. In this tutorial …
C Program to demonstrate Enumeration. An enum(Enumeration) is a user-defined type consisting of a set of named constants called enumerators. This Program will return the month in a year. I.E. It returns 9 for September.

The do-while loop in C is a post-test loop: it executes the body first and checks the condition afterward. This guarantees the body runs at least once, regardless of the condition’s initial truth value. This is the key difference from the while loop, which checks the condition before the first iteration and may never execute …
