In this article, you will learn how to find the length of a string without using a string header file and loops in C. I will explain two ways to solve the problem of finding the string length without <string.h> and loop. But before understanding the solution let’s first understand what string is in C.

The localtime function in C converts the calendar time pointed to by the timer into a broken-down time, expressed as local time. The localtime function is present in the <time.h> header file. Syntax of localtime: The prototype of the localtime () function is below: #include <time.h> struct tm *localtime(const time_t *timer); Parameters: The

The gmtime function in C converts the calendar time pointed to by the timer into a broken-down time, expressed as UTC. That means it uses the value of the time_t object to fill a tm structure with the values that represent the corresponding time, expressed in Coordinated Universal Time (UTC) or GMT timezone. Syntax of
